Method for dyeing coating film

Abstract

Abstract PURPOSE:To simply obtain a deep color dyed pattern film by using m- nitrobenzenesulfonate and/or urea as a deep color dyeing agent. CONSTITUTION:When a practically colorless dyeable photosensitive material is applied to a substrate, exposed through a prescribed mask and developed and the resulting coating film (pattern film) is dyed, m-nitrobenzenesulfonate and/or urea is used as a deep color dyeing agent to obtain a deep color dyed pattern film. This colored pattern film is useful as a color filter for a color solid-state image pickup element, a color liq. crystal display device or the like.
