Abstract
The present invention is a silver halide photographic element which includes a support, at least one light sensitive silver halide emulsion layer, and an antihalation undercoat layer interposed between the at least one light sensitive silver halide layer and the support. The antihalation undercoat layer includes a hydrophilic binder and an ultraviolet ray absorbing polymer particle having a mean size of greater than 0.01 .mu.m. The ultraviolet ray absorbing polymer particle includes an ultraviolet ray absorber and a polymer derived from monomer A and less than 10 weight % of monomer B, wherein monomer A represents ethylenically unsaturated monomers which form substantially water insoluble homopolymers, and monomer B represents ethylenically unsaturated monomers capable of forming water soluble homopolymers.
