Title:
PRODUCTION OF COLOR FILTER
Document Type and Number:
Japanese Patent JPS6411201
Kind Code:
A
Abstract:
PURPOSE:To obtain a color filter having good accuracy with decreased stages by providing an active film layer consisting of a metal oxide and ink layer contg. a coloring material, migrating the coloring material to color the active film layer, and sealing the active film layer with a thin metallic film layer, then removing the ink layer and the thin metallic film layer. CONSTITUTION:The active film layer 2 consisting of the metal oxide such as active alumina or active silica is formed on a transparent substrate 1 consisting of a glass plate, synthetic resin plate or synthetic resin film and the ink layer is patterned and laminated on the active film layer 2. The coloring material ion the ink layer 3 is then migrated into the fine pores in the active film layer 2 and thereafter, the thin metallic film layer 4 is formed by electroless plating on the active film layer 2 formed with the ink layer 3. The substrate is immersed in warm water kept at >=90 deg.C or aq. nickel acetate soln. kept at >=90 deg.C to seal the pores in order to prevent the elution of the coloring material adsorbed into the fine pores of the active film layer 2. The unnecessary ink layer 3 formed on the active film layer 2 and the unnecessary thin metallic film layer 4 formed on the ink layer 3 are removed. The need for the registration for the purpose of black matrix formation is thereby eliminated and the generation of a misregistration is obviated. The stages are thus simplified and the rate of non- defective articles is improved.
