  • High optical contrast pigment and colorful photosensitive composition employing the same and fabrication method thereof
    Patent number: 8168689
    Abstract: A high optical contrast pigment and colorful photosensitive composition employing the same are disclosed. The composition comprises a solvent, an alkali-soluble resin, reactive monomer, and a modified pigment which has low crystallization. The low crystallization degree means that the grain size variation R is not more 80%, wherein the grain size variation R is represented by a formula R=G1/G0×100%, G0 is the original grain size, and G1 is the grain size after modification.
    Type: Grant
    Filed: April 7, 2008
    Date of Patent: May 1, 2012
    Assignee: Industrial Technology Research Institute
    Inventors: Chin-Cheng Weng, Kuo-Tung Huang, I-Jein Cheng, Ming-Tzung Wu, Yu-Ying Hsu, Chiang-Yun Li
