Abstract
Abstract A water-proof support of photographic paper comprising a substrate and a white pigment-containing resin layer provided on at least one surface of the substrate, in which the resin layer comprises a white pigment dispersed in a polymer binder made by polymerization of a unsaturated compound containing a tetraacrylate ester of pentaerythrithol alkylene oxide adduct. An adhesive layer may be provided between the substrate and the white pigment-containing resin layer.
