Technical Development

Tokyo Ink Technologies, which we have honed with a diversity of coloring materials, are comprised of five core technologies:
1) pigment dispersion; 2) resin modifying; 3) molding; 4) production; and 5) analysis evaluation.
Combining these core technologies, we have developed colorants and functional products that cater to demands in a wide range of sectors.

Core Technology
  • Core TechnologyPigment dispersion technologyColoring materials easily coagulate. Uniformly and stably dispersing color materials is a crucial technology for coloring. We have perfected dispersion-related formulation and processing technologies for a wide range of base materials such as liquids and solids. This technology can be applied to other functional materials as well as coloring materials.
  • Core TechnologyResin modifying technologyBinders used for ink are important for printed matter, such as colored components of ink and adhesiveness with base materials. We carry out design in line with physical property requirements for various substrate materials.
  • Core TechnologyPlastic forming technologyTo form complex-shaped plastics, we have accumulated die design technology and knowledge of optimum molding conditions. This technology is used in the development of various industrial materials such as civil engineering materials, and is applied to a diversity of packaging materials.
  • Core TechnologyProduction technologyWe have streamlined production systems, built new production systems, and examined unique and new devices. We have made the deployment and application of production technology a fundamental technology of “monozukuri”.
  • Core TechnologyAnalysis evaluation technologyTechnology that correctly evaluates the performance of products used in various sectors underpins production technology together with “monozukuri”. We provide stable products using a wealth of analytical equipment and evaluation technology supported by evaluation knowledge.
