A support sheet for a photographic printing sheet having enhanced anti-fogging and anti-yellowing properties comprises a pulp paper substrate sheet, a front coating layer formed on a front surface of the substrate sheet and comprising a cured resinous material produced from electron beam-curable unsaturated organic compound by an electron beam irradiation thereto and mixed with a white pigment, and a back coating layer formed on a back surface of the substrate sheet and comprising a film-forming synthetic resinous material, in which a magnesium compound is contained, as an anti-fogging agent, in the substrate sheet and/or the front coating layer.

A support sheet for a photographic printing sheet having enhanced anti-fogging and anti-yellowing properties comprises a pulp paper substrate sheet, a front coating layer formed on a front surface of the substrate sheet and comprising a cured resinous material produced from electron beam-curable unsaturated organic compound by an electron beam irradiation thereto and mixed with a white pigment, and a back coating layer formed on a back surface of the substrate sheet and comprising a film-forming synthetic resinous material, in which magnesium hydroxide is contained, as an anti-fogging agent, in the substrate sheet.

A thermal transfer image-receiving sheet for recording thereon colored dye images having a high clarity and color density and an excellent storage durability, comprises an image-receiving resinous layer formed on a substrate sheet and comprising a resinous material which is an actinic ray irradiation curable product of a precursory resinous composition comprising (A) an unsaturated acrylic or methacrylic ester compound having a rosin or modified rosin residue, (B) another acrylic or methacrylic ester compound having a bisphenol A residue, at least one ethylene glycol residue and at least two terminal acrylic or methacrylic ester residue, and optionally (C) still another unsaturated acrylic or methacrylic ester compound having a single terminal acrylic or methacrylic ester residue.

Thermal transfer image-receiving sheet

A support sheet for photographic printing paper having an undercoat layer on which a photographic emulsion layer is to be formed, and which is free from foaming, contamination by foreign substances, and putrefaction and does not effect the photographic emulsion, by the steps of coating front and back surfaces of a substrate sheet with polyolefin resins; surface-activating the front coating layer; and extrusion coating the activated surface of the front coating layer with a coating liquid comprising gelatin, through a slit-shaped orifice, to form the undercoat layer.
