Abstract:
1. A method of producing a color filter, comprising the steps of: preparing a color filter master plate comprising a recording layer comprising a polymer compound containing a polarity conversion group with a polarity character thereof being changeable by heat or irradiation; exposing, by heating or light-beam irradiation, the color filter master plate, thereby changing the polarity character of a surface of the recording layer; and causing a dye or a pigment to be adsorbed at regions of the surface of the recording layer where the polarity character has been changed, wherein the polarity conversion group is represented by at least one of the following general formulae (1) or (3): in which L represents an organic group comprising a multivalent non-metal atom necessary for bonding to a polymer skeleton, R 1 and R 2 each independently represent a substituted or unsubstituted alkyl group, and R 1 and R 2 may form a ring with a secondary carbon atom, represented by CH, bonded thereto, in which X represents a group selected from among —O—, —S—, —Se—, —N 8 —, —CO—, —SO—, —SO 2 —, —PO—, —SiR 8 R 9 —, and —CS—; R 6 , R 7 , R 8 , and R 9 each independently represents a monovalent group; and M represents a positively charged ion.
