Changing colours with changing times




In an interview, Jeff Okaichi, Director and Vice President, Toyocolor Co Ltd (Toyo Ink Group company), with Chemical Today Magazine focuses on the growing dynamics of the inks and pigments industry due to wider application range and need for innovative ink and pigment solutions.

Global trends in inks & pigments industry.
Increased global awareness with respect to food safety and reducing the impact of packaging on the environment has been driving the demand for packaging inks and materials with lower migration or enhanced eco-friendly characteristics. The demand for clean, sustainable pigments, including aqueous types and compositions free of VOCs, halogens and amines continues to grow. While our food packaging grade of organic pigments, resins and inks have been specially formulated to meet today’s strictest environmental requirements, we continuously focus on the development of high grade pigment technology that imparts the higher color stability and viscosity levels that will be required by the next-generation of inks, paints and coatings.
We continue to see growing interest in UV and digital printing markets which has been driving the demand for high quality pigment dispersions to help formulate inks and coatings for these applications. As such, the challenge for pigment manufacturers is to develop pigment formulations that can meet the varying quality requirements in terms of particle size and electrical conductivity. We expect to see new developments in UV- and inkjet-grade technology and their materials for high-speed commercial printing in years to come.
Advancement in colour demand for inks & pigments.
Toyocolor dispersion processing technology is used in carbon nanotubes and other next-generation inorganic materials to support the future evolution of color materials. As part of our growth strategy, we are working to develop innovative pigments that help manufacturers meet the functional and performance demands of advanced inks and coatings. Specifically, we will be working to develop and expand sales of products using unique pigments and nano-level dispersion technologies, including products with optical and insulation functions that are relatively new to the market.
