Claim:
1. A colored photo-sensitive composition comprising: (A) a resin which is increased, by action of an acid, in solubility into an alkali developing solution; (B) a pigment; (C) a compound which produces an acid upon irradiation by active light or radial ray; and (D) a solvent, wherein the colored photo-sensitive composition has a ratio of content of the (B) pigment of 20% by mass or more, relative to the total solids of the colored photo-sensitive composition, wherein the (A) resin which is increased, by action of an acid, in solubility into an alkali developing solution further has an acid group, wherein the acid group is a carboxylic acid group; and the (A) resin which is increased, by action of an acid, in solubility into an alkali developing solution still further has, in a side chain, an oligomer or polymer chain having a weight-average molecular weight of 500 to 100,000.
