<p>PURPOSE:To provide a photosetting resin compsn. having high sensitivity to exposure with UV, developable with an aq. alkali soln. and most suitable for use as the material of a protective layer for a color filter layer having excellent chemical and heat resistances and adhesion to the substrate, to form a protective layer with the photosetting resin compsn. and to provide a color filter with the protective layer. CONSTITUTION:This photosetting resin compsn. contains a polymer having carboxyl groups in the molecule, a compd. having at least two ethylenic unsatd. double bonds in the molecule, a photopolymn. initiator and a compd. having at least one epoxy group in the molecule. The polymer having carboxyl groups in the molecule is a copolymer contg. repeating units derived from at least one kind of compd. selected among acrylic acid, methacrylic acid, benzyl acrylate and benzyl methacrylate or these compds. and alkyl methacrylate having a 1-12C alkyl group.</p> |
