PURPOSE: To provide the title composition which can give a film of sufficient strength even when cured at low temperatures, excels in transmittance of visible light and is suited for the production of a protective film by mixing a glycidyl acrylate polymer with a hydroxystyrene polymer and a polycarboxylic acid (anhydride). n CONSTITUTION: A polymer comprising 50wt.% or above structural units of formula I (wherein R 1 is H, methyl, ethyl or propyl; and m is 1-5), e.g. glycidyl acrylate/methyl acrylate copolymer, is mixed with a polymer comprising 20wt.% or above structural units of formula II (e.g. p-hydroxystyrene/methyl acrylate copolymer) and a polycarboxylic acid (anhydride), e.g. maleic anhydride, to produce a thermosetting resin composition. By dissolving the obtained composition in a solvent, applying the obtained solution to a color filter and baking the film, a transparent and tough protective film can be formed on the color filter. n COPYRIGHT: (C)1992,JPO&Japio |
