  • Patent number: 8182968
    Abstract: The present invention provides a method for producing a color filter, the method including: applying an adhesion auxiliary agent onto an inorganic material; forming a curable layer on the inorganic material to which the adhesion auxiliary agent has been applied by applying a curable pigment composition containing an organosilane compound (A) represented by Formula (I) below (wherein L is a monovalent organic group; R1 and R2 are hydrocarbon groups; and n is an integer from 1 to 3), a photopolymerization initiator (B), a compound (C) having an ethylenically unsaturated double bond, and a pigment (D); exposing the curable layer to light in a pattern using a mask; and a developing the curable layer after exposure to form a color pattern.
