Abstract

PURPOSE:To obtain a photographic support without causing a die lip stain by coating at least one side of a paper or synthetic paper substrate with a film of a polyolefin resin composition contg. TiO2 and having specified viscosity by melt extrusion. CONSTITUTION:In the manufacture of polyolefin resin coated paper for photography by coating at least one side of a paper or synthetic paper substrate with a film of polyolefin resin composition contg. TiO2 by melt extrusion, the composition is composed of polyolefin resin (A), TiO2 (B) with <=0.35% loss on drying at 110 deg.C for 2hr and a metallic salt of higher fatty acid (C) such as zinc stearate, and the apparent melt viscosity of the composition at 20 deg.C is adjusted to <=5X10<4> cps at 5X10<3>/sec shear rate. Thus, no die lip stain is caused during the manufacture of the photographic support, so the formation of a defective surface can be prevented.
