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.
