Abstract
A polyolefin resin composition containing 5 to 150 ppm of an antioxidant and a high-concentration (e.g. 40 to 80% by weight) titanium dioxide pigment is diluted with a polyolefin resin to prepare a medium-concentration (e.g. 20 to 60% by weight) titanium dioxide pigment-containing photographic master batch, then this master batch is further diluted with a polyolefin resin to form a low-concentration (e.g. 5 to 20% by weight) titanium dioxide pigment-containing resin composition, and this resin composition is melt extruded and coated on a support made of paper or a synthetic paper to produce photographic resin coated paper. According to this process, both die lip staining and formation of microgrits are prevented.
