INK COMPOSITION FOR COLOR FILTER

摘要

PURPOSE:To obtain an ink composition excellent in heat resistance, liquid crystal resistance, light resistance, etc., capable of forming a fine pattern and mass- producible at a low cost by using a polyester acrylate-based resin as the main component and blending a solvent and a pigment therewith. CONSTITUTION:The objective composition is composed mainly of a polyester acrylate-based resin preferably composed of a polyfunctional oligoester acrylate represented by the formula (A is an acrylic acid residue; X is a polyvalent alcohol residue; Y is a polybasic acid residue; (n) is 0 to 3) and further contains a glycol ether-based solvent such as ethylene glycol monomethyl ether and a pigment.
