Method for producing color filter

A method for producing a color filter comprising the steps of:

• (A) forming a photosensitive coating film on an electrically conductive layer formed on a surface of a substrate, and exposing said photosensitive coating film through a mask having patterns of at least three different degrees of light transmittances;
• (B) developing and removing a photosensitive coating film portion corresponding to a pattern selected from the group consisting of a pattern having the smallest degree of light transmittance and a pattern having the largest degree of light transmittance for exposing said electrically conductive layer and electrodepositing a colored coating on the exposed electrically conductive layer for forming a colored layer thereon, operation of developing and removing the photosensitive coating film followed by electrodeposition being repeated for the respective patterns having different degrees of light transmittances in one sequence selected form the group consisting of increasing light transmittance and decreasing light transmittance for producing different colored layers, respectively;
• (C) selectively forming a metal layer interstices present between the colored layers, and
• (D) transcribing said colored layers and said metal layer onto another substrate.
