Abstract:
1. A photosensitive composition, which comprises a polymer (A) having a side chain containing a group represented by the formula: wherein X is a hydrogen atom, a fluorine atom or a trifluoromethyl group, R f is a C 1-20 fluoroalkyl group which may have an etheric oxygen atom or a fluorine atom, or a group represented by the formula: wherein each of R 1 and R 2 which are independent of each other, is a hydrogen atom, an alkyl group, a cycloalkyl group or an aryl group, R 3 is a hydrogen atom or a C 1-10 organic group, and n is an integer of at least 1 and at most 200; and a side chain containing an ethylenic double bond, a black colorant (B), a photopolymerization initiator (C), and a photosensitive resin (D) containing an acidic group and an ethylenic double bond, wherein the polymer (A) has a number average molecular weight of at least 2×10 4 and at most 7×10 4 and a weight average molecular weight of at least 5×10 4 and at most 25×10 4 .
