Production of color filter

カラーフイルタの製造方法

Abstract

PURPOSE:To ensure uniform tight adhesive property between a transparent substrate and colored picture elements and to stably obtain a high quality color fitter by treating the surface of the substrate with a primer soln. contg. a specified compd., forming a prescribed colored layer on the treated surface and further forming a transparent resin layer on the surface of the colored layer. CONSTITUTION:The surface of a transparent substrate is treated with a primer soln. contg. a compd. represented by the formula, a prescribed colored layer having a multicolored pattern is formed on the treated surface and a transparent resin layer is further formed on the surface of the colored layer. In the formula, R is 1-5C alkoxysilylpropyl and (m) is an integer of 3-200. The compd. represented by the formula is alkoxysilylpropylpolyethyleneimine and concrete examples of the compd. include trimethoxysilylpropylpolyethyleneimine and dimethoxy-methylsilylpropylpolyethyleneimine. Such a compd. is diluted with an org. solvent to prepare the primer soln.
