<p>PURPOSE:To improve an adhesion property, light resistance, heat resistance, transparency and surface flatness after coating and curing by constituting the thermosetting compsn. of a specific vinylic polymer, acid anhydride and alicyclic polyepoxide. CONSTITUTION:This thermosetting compsn. consists of (A) a vinylic polymer contg. >=20 to <60wt.% glycidyl group-contg. vinylic monomer units, (B) acid anhydride and (C) alicyclic, polyepoxide. This surface protective agent for color filters consists of such compsn. The vinylic polymer (A) is a copolymer consisting of >=1 kinds of the glycidyl group-contg. vinylic monomers and >=1 kinds of other vinylic monomers. The glycidyl group-contg. vinylic monomers and the other polymerizable monomers may be bonded to blocks or may be randomly bonded. Further, glycidyl methacrylate is more preferable as the glycidyl group-contg. vinylic monomers.</p> |
