<p>PURPOSE: To improve printing property, heat resistance and adhesion property by preparing the compsn. by dispersing soluble polyimide siloxane, epoxy resin and coloring pigments. CONSTITUTION: This ink compsn. for a color filter is prepared by uniformly kneading 100 pts.wt. soluble polyimide siloxane, 1-50 pts.wt. epoxy resin, 10-300 pts.wt. coloring pigment, and soluble org. solvent. The polyimide siloxane is prepared by polymerizing and imidizing an aromatic tetracarboxylic acid component essentially comprising 2,3,3',4'-biphenyl tetracarboxylate and a diamine component comprising 45-80mol% diaminopolysiloxane expressed by formula, 0.5-40mol% diamino benzoate and the balance aromatic diamine having two or more benzene rings. In formula, R1 is a bivalent hydrocarbon group, R2 is independently C1-C3 alkyl group or phenyl group, and n is an integer 3 to 30. Thereby, a color filter comprising a flat film can be formed.</p> |
