PRODUCTION OF COLOR FILTER

摘要

PROBLEM TO BE SOLVED: To provide a process for producing color filters capable of efficiently producing the color filters having excellent dimensional accuracy, optical characteristics and surface smoothness. SOLUTION: Colored electrodeposition films of a desired number of colors including light shieldable colored electrodeposition films are formed in such a manner that novolak resin are interposed between at least light shieldable colored electrodeposition films 8 and the other colored electrodeposition films adjacent thereto by repeating the operation for forming transparent conductive layers 3 over the entire surface or in prescribed regions of a transparent substrate 2 in a first stage, forming positive photoresist layers 4 consisting essentially of such novolak resins which satisfy at least either of the weight average mol.wt. of the novolak resins contained therein within a range of 3000 to 1000 and the content of sensitizers within a range of 15 to 30wt.% on at least the transparent conductive layers 3 of the transparent substrate 2 in a second stage, exposing and developing these positive photoresist layers 4 via a photomask having prescribed patterns and forming the colored electrodeposition films 8 on the exposed transparent conductive layers 3 in third stage.
