Abstract

A cationic high-molecular weight compound is represented by formula (I): ##STR1## wherein R¹ and R² may be the same or different and each represents a hydrogen atom or C_1-6 lower alkyl group; L¹ represents --COO-- or --CONH-- and L² represents a divalent group; J represents a C_1-20 alkylene group or C_7-20 aralkylene group; R³, R⁴ and R⁵ may be the same or different and each represents a C_1-20 alkyl group or C_7-20 aralkyl group; X^- represents an anion; A represents a repeating unit made from a polymerizable monomer; n represents a number-average polymerization degree of 2 or more; Y represents a monovalent connecting group; B represents an ethylenically unsaturated monomer containing at least two ethylenically unsaturated groups or a repeating unit made from N-methylol (meth)acrylamide or N-alkylether (meth)acrylamide; D represents a repeating unit made from an ethylenically unsaturated monomer; and p, q, r and s each represents a monomer component weight percentage, with the proviso that p, q, r and s are 1 to 99% by weight, 0.5 to 70% by weight, 1 to 40% by weight and 0 to 98% by weight, respectively, and p+q+r+s=100. A silver halide photographic material contains constituent layers including at least one light-sensitive silver halide emulsion layer on a support, wherein at least one of the constituent layers contains such a cationic high-molecular weight compound.
