Abstract

PURPOSE: To improve the chemical resistance of the organic color filter for image pickup tubes for color televisions or color solid state image sensing devices by processing the dyed coloring resin films with the specific aqueous solution thereby surface-modifying the same.
CONSTITUTION: A resin film 6 is formed on a substrate 1 and a dyeing mask 7 is formed through coating of photo resist, exposure through the mask and developing. Next, the non-mask portions of the film 6 are dyed and rinsed, after which the resin surfaces of the colored portions are modified to have chemical resistnace by aqueous solution processing of tannic acid and acetic acid, potassium antimonyl tartrate aqueous solution processing, rinsing and drying. Thereafter, the mask 7 is removed, whereby the coloring stripes 8 for the first color are formed. The similar processes are repeated to yield the stripe filter composed of 3 colors of highly chemical resistant red, green and blue. If necessary, a protection film 3 is provieded thereon. Thereby, the resistance to adhesives used for affixing to thin plate glass in particular is improved.
