Dispersion is the uniform distribution of fine particles (filler), each of which has a size of several micrometers to several nanometers, in a liquid or solid (dispersion medium). Our group has the technology to design special dispersants and dispersion resins (polymers) to suit fillers and dispersion media, and to create dispersions with arbitrary particle sizes to suit purposes. Furthermore, by controlling the degree of dispersion so that the filler is in an ideal state during film formation, and by dispersing the particles as finely as possible, we are developing a variety of products that maximize the functionality of the filler.
Application technology of dispersion
In addition to forming films on base materials, precision coatings allows for casting technology that turns polymer into films, foreign matter/defect management, film thickness control, patterning coating, dry edge processing, lamination/multilayering of functional layers, etc. We have the technology. By combining our group's polymer design technology and dispersion technology with coatings technology, we maximize the functionality of the sheet. With a focus on adhesive tape products, we offer a wide range of products ranging from daily necessities to cutting-edge electronics materials and pharmaceuticals.
Application technology of coatings
Many of our group's products use technology that "polymerizes monomers into polymers." By designing the primary structure such as molecular weight, glass transition temperature, branching, and number of functional groups, and also designing the secondary structure of particulate polymers, the performance of the polymer when it finally forms a film (e.g. , adhesion, crosslink density, elongation, refractive index, dielectric constant, etc.). We actively work on new synthesis, processing, and analysis methods, and utilize a variety of polymer design technologies to respond to social issues and customer needs.
Application technology of polymer design
Color Material Design
Using organic pigments synthesis technology, which is one of the origins of our group, we are developing materials that can control wavelengths not only in the visible light but also in the ultraviolet and near-infrared regions.
Furthermore, by combining polymer design technology, dispersion technology, and coatings technology to design the material's refractive index and film structure, we can arbitrarily control light transmission, absorption, reflection, and diffusion, improve material durability, and increase energy efficiency. We are working on technology that enables improved usage efficiency.
Applied technology for color material design
The Group makes full use of various analysis methods and abundant know-how to quickly investigate the causes of development issues and product quality problems and solve them in a short period of time. In particular, with regard to nano-level microstructure control, which is the key to the functional expression of many of our products, we strongly support product development with the latest equipment and proprietary technology for processing samples under optimal conditions.
In addition, we are working on data-driven development (materials informatics) that improves the speed of product development by analyzing accumulated experimental and paper data to search for materials and predict physical properties, as well as sensor devices that utilize our own materials and technologies, and new services based on that data.

This product has good fluidity (easy to apply to substrates) and high transparency by making full use of nano-level dispersion technology cultivated through the development of printing inks and coatings, and by making pigments finer and dispersing it uniformly. We also offer a low-temperature curing type color filter resist inks that can be applied not only to glass but also to plastic substrates, etc. and contributes to reducing environmental impact.
Our group has so far produced "biomass" products that use plant-derived raw materials, "water-based" products that use water as the main ingredient instead of organic solvents, and resins that are gradually decomposed into water and carbon dioxide by bacteria in the soil. We have been providing environmentally-friendly products for packaging in the form of materials such as inks and adhesives, such as biodegradable products using .
In order to realize a further recycling-oriented society, we are utilizing our group's peeling and deinking technologies to build a "material recycling system" that aims to collaborate and promote not only materials but also local governments, companies, and local communities. .
Our group has cultivated dispersion technology and polymer design technology, as well as coatings technology that uses these resins to form sheets and rolls into thick films, thin films, and laminates. By combining these technologies, we provide functional sheets and tapes to the rapidly developing electronics market, especially the high-speed communication and semiconductor markets, as well as resin materials, adhesives, and other products that we have accumulated technology for. .
Our group is working to utilize bioplastics (a collective term that combines "biodegradable plastics" that are biodegradable by microorganisms and "biomass plastics" that use biologically derived raw materials) to realize a resource recycling society. . In particular, our biodegradable product group uses biomass and biodegradable polylactic acid (PLA) as the main raw material, and we design and manufacture the polymer in-house depending on the application. Using advanced polymer design technology and expert blending and formulation technology, we provide a group of biodegradable products that have the same level of quality as conventional products.
Paint alternative technology
The painting process, which protects the car body and enhances its design, accounts for 20% of the CO 2 emissions from the vehicle manufacturing process, and there is a need for alternative paint technology. Our group has long provided marking films (pasting paints) for signs, advertisements, bus wrapping, etc., but we have further improved our technology in terms of durability, design, moldability, etc., which will lead to environmental friendliness in all situations. We will provide alternative paint materials.
