<p>PROBLEM TO BE SOLVED: To form red, green, blue and block images excellent in spectral transmission characteristics, rigidity against heat and rigidity against light by incorporating specified plural polymer couplers. SOLUTION: The photosensitive material contains two one more kinds of polymer couplers (A) to (C). (A) is a copolymer derived from a yellow coupler monomer expressed by formula I and a magenta coupler monomer expressed by formula II, (B) is a copolymer derived from a yellow coupler monomer expressed by formula I and a cyan coupler monomer expressed by formula III, (C) is a copolymer derived from a magenta coupler monomer expressed by formula II and a cyan coupler monomer expressed by formula III. In formulae I to III, Ru1 , R<3> , R<6> are hydrogen atoms, alkyl groups, etc., L1 . L3 , L5 are -C(=O)O-, etc., L<2> , L<4> , L<6> are bivalent connecting groups to bond L<1> and Q<1> , Q<1> -Q<3> are coupler residues for the respective colors to form yellow, magenta and cyan dyes.</p> |
