The Toyo Ink Group will contribute to the creation of a sustainable society by providing value in each of its business segments to help solve social issues such as climate change, resource depletion, information gaps, low birthrates, an aging population and natural disasters.

Japan's greenhouse gas (GHG) emissions are approximately 1,323 million tons,* of which more than 90% consist of carbon dioxide. GHG emissions in FY2015 were 6.0% low-er than FY2013, with another 20% reduction required by FY2030.

Although biomass generates CO2 when burned, the plants that serve as biofuel absorb CO2 as they grow, mak-ing biomass carbon neutral overall as it does not increase CO2 levels.

Biomass is also used in products such as biomass plas-tics. In May 2016, Japanese cabinet decided on the Plan for Global Warming Countermeasures, which sets a GHG reduction goal of 720,000 tons by fiscal 2020 and 2.09 million tons by fiscal 2030. To achieve these goals, it will require an expansion in the use of biomass products.* Japan Ministry of the Environment, “FY2015 greenhouse gas emissions (�nal

Biomass Solutions

Value Provision by the Toyo Ink Group

As the printing and packaging �elds accelerate themselves toward carbon dioxide emissions reductions, the entire Toyo Ink Group is actively promoting the development of biomass products in its role as a leading manufacturer of printing inks.

In addition to offset, gravure and �exo inks, we are developing biomass products related to packaging such as laminating and hot-melt adhesives, and working to propose biomass solutions.

1. Objective Evaluation and Indication of Fact-based Information

With regard to the use of plant-derived materials to reduce carbon dioxide emissions, we emphasize clarification of evidence and objectivity. As a means to those ends, we are being thorough in developing products based on the accreditation standards of the Japan Organic Resources Association. All Toyo Ink biomass products derived from plant-based materials have earned the association’s biomass certi�cation mark.

2. A Biomass Product Selection that Covers Major Printing Methods

Offset, gravure and flexo printing methods account for about 70% of the printing ink market. Having introduced biomass inks to these printing methods, we can contribute to the realization of a sustainable society through packag-ing and various printed matter for foods and daily necessi-ties.

With respect to the packaging �eld, we are contributing to solving social issues not only through printing ink, but also by having a lineup of other biomass products such as laminating adhesives and hot-melt adhesives.

■ Features of Biomass Solutions

Toyo Ink Co., Ltd. is working to develop environmentally friendly products such as toluene-free, MEK-free and

water-based inks for gravure and �exo print packaging.

As a further environment response, we have successfully developed biomass products (biomass solutions) as

a key way to contribute to the building of a recycling-oriented society that uses petrochemical-free, naturally-

derived materials as well as the reduction of CO2.

Through launching these products ahead of other companies and having them adopted as private brands by

convenience stores, they are reaching the hands of consumers.

Aiming to further reduce environmental burdens with biomass solutions.

In July 2017, Britain and France announced a policy they

would not approve sales of gasoline and diesel vehicles that

use fossil fuels after 2040. In China, NEV regulations (reg-

ulations for new energy vehicles), which oblige automobile

manufacturers to sell electric vehicles, plug-in hybrid vehi-

cles, fuel cell cars, etc., will be implemented from 2019. In

response to these developments, the move to electric vehi-

cles continues to gain traction.

Many issues with electric vehicles remain, such as short

ranges and long charge times, which will call for a high-out-

put, compact battery.

CNT Dispersants for Lithium-ion Batteries

Lithium (Li) ion batteries are lightweight, high-voltage and large-capacity,

making them useful for smartphones, laptops and other electronic infor-

mation devices as well as in electric vehicles.

Toyo Color’s 2nd-generation carbon nanotube (CNT) dispersants for Li-

ion batteries are a proprietary technology developed by the Toyo Ink Group

over many years and have been commercialized by carefully selecting both

dispersants and CNTs.

Compared with CNT dispersants from other companies, an addition of

50% more dispersants in our products contributes to high battery capacity

through high conductivity ef�ciency. This addition also improves the adhe-

siveness of the electrode sheet, allowing reductions in the amounts of con-

ductive assistants and binders added. Moreover, as high-purity CNTs are

used, foreign matter is kept to a minimum, which improves battery safety. 0.2　 0.3　 0.4　 0.5　 0.6　 0.7　 0.8　 0.9　 1　 1.1

Our 2nd-generation CNT dispersion agent was developed for Li-ion batteries using our accumu-lated dispersion know-how; the addition of small amounts of dispersant can form a highly ef�-cient conductive path (for electrons).

We will continue to make future improvements to solve the problems with Li-ion batteries us-ing this technology and contribute to electric vehicles with long ranges and short recharge times.

Image sensors are essential to the collection of big data

for an information and communications technology (ICT)

society. Several such sensors are installed in a vehicle, and

they are also used for collision detecting and automatic

braking systems.

With the realization of autonomous driving, image

sensors will likely become basic infrastructure, which

will require miniaturization and improved performance

of cameras, as well as a smaller color filters with higher

resolutions.

Development and provision of image sensor materials for an ICT society

On-chip Color Resists for Image Sensors

We have developed materials for color filters to provide beautiful coloring in displays. As we continue to involve into an ICT society, our company is advancing its development of sensor materials for a wide variety of applications, including automatic operations, robotics, security and medicine in order to support people’s lives safely and conveniently. We will work together as one with the aim of developing and supplying products that contribute to a sustainable society.

Imaging Internet of Things (IoT)

Image sensors consist of three layers: a micro lens, a color �lter and a photo

diode. For the color �lters on smartphones and the like, the pixel size is only

about 1 µm×1 µm, and the pigment particles on the filter’s on-chip color

resist must be dispersed extremely �nely and uniformly. The image sensors

for surveillance cameras and endoscopes, on the other hand, must be able to

sense light of various wavelengths, such as infrared or ultraviolet rays, in ad-

dition to visible light.

Toyo Visual Solutions makes use of its proprietary technologies to realize

nano-level dispersion. We have also succeeded in the design of a new disper-

sant for stable distributing even high concentrations of pigment and thinned

filter membranes. Our own synthesis and dispersion technologies have

allowed us to provide color materials that can sense non-visible light wave-

lengths, which contributes to the multifunctionality of image sensors.
