ABSTRACT:
Disclosed is silver halide photographic photosensitive material comprising a support, having thereon at least one silver halide photosensitive emulsion layer, wherein a polymer which can be represented by the following general formula (I) is included in at least one of the structural layers of the photographic photosensitive material: ##STR1## The term A represents a repeating unit obtained by polymerizing a monomer which has at least two polymerizable ethylenically unsaturated groups of which at least one is in a side chain; B represents a repeating monomer unit obtained by the polymerization of a monomer which has one polymerizable ethylenically unsaturated group; R.sup.1 represents a hydrogen atom or an alkyl group; R.sup.2 and R.sup.3 each represents a hydrogen atom or a methyl group; R.sup.4 represents a hydrogen atom or an organic group; L.sub.1 represents a divalent group comprising at least three atoms by which the main macromolecular chain and the poly(ethylene oxide) unit are linked; m represents an integer of at least 10, and x, y and z indicate percentages by weight wherein x is from 0 to 30, y is from 0 to 95 and z is from 5 to 100, based on the total weight of the polymer.
