<p>PURPOSE:To provide the color filter for liquid crystal display having good heat resistance, light resistance and transparency and the process for producing the color filter by dispersing pigments at a high degree into the acrylic resin expressed by the specific general formula. CONSTITUTION:The surface of a transparent substrate is coated with colored resin compsns. essentially consisting of the acrylic resin, org. dyestuffs, dispersants, and solvents to form the colored filter layers by each color to desired pattern shapes in an arbitrary number of colors. The monomers expressed by the general formulas I to III are used as the monomers constituting the acrylic resin. The acrylic resin is a copolymer having the compsn. ratios consisting of 5 to 30pts.wt. formula I, 20 to 40pts.wt. formula II and 40 to 60pts. wt. formula III. R is H or CH3 and n, m are 0 to 6 integer. The dyestuffs are preferably pigments in terms of the heat resistance and light resistance. Derivatives which have a substituent in the org. dyestuff and are effective for dispersion in the dyestuffs are used for the dispersants.</p> |
