Abstract:
An image recording element having a protective overcoat thereon, the protective overcoat formed by the steps of:providing an image recording element having at least one silver-based light-sensitive emulsion layer; applying to the at least one silver-based light-sensitive emulsion layer an aqueous overcoat composition comprising 30 to 95 weight percent, based on the dry laydown of the overcoat, of hydrophobic polymer particles having an average size of 0.01 to 0.5 micrometers, said hydrophobic polymer being a homopolymer of the monomer described in Structure 1 or a copolymer containing at least 30 percent by weight, based on total weight of monomers, of the monomer described in Structure 1 and 5 to 70 weight percent of crosslinked gelatin, based on the dry laydown of the overcoat, said hydrophobic polymer exhibiting a glass transition temperature, but not a melting point; processing the at least one silver-based light sensitive emulsion layer to provide an imageed recoridng element; and subjecting the hydrophobic polymer particles to provide the imaged recording element to fusing, including the application of pressure and heat to the image recording element, at a temperature higher than 300Â° F. to provide a photographic element having a protective overcoat: wherein:R is H, CH3, C2H5, or C3H7; and X1, X2, X3, X4 and X5 are H, F, Cl, Br, I, CN, CH3O, C2H5O, C3H7O, C4H9O, CH3, C2H5, C3H7, n-C4H9, sec-C4H9, tert-C4H9, CF3, C2F5, C3F7, iso-C3F7, n-C4F9, sec-C4F9, tert-C4F9, CH3NH, (CH3)2N, n-C5H11, C4H9, n-C6H13, n-C7H15, n-C8H17, n-C9H19, n-C10H21, or n-C12H25.
