摘要： Disclosed are resin-coated paper having on one side of its base paper a first resin layer made of a resin composition obtained by melt-blending 90 to 65 parts by weight of a high-density polyethylene resin having a melt flow rate of 10.0 g/10 min to 40.0 g/10 min and a density of 0.960 g/cm.sup.3 or more and 10 to 35 parts by weight of a low-density polyethylene resin or a medium-density polyethylene resin, which has a melt flow rate of 0.2 g/10 min to 2 g/10 min, a density of 0.935 g/cm.sup.3 or less, a percentage of molecules with a molecular weight of 500,000 or more of 10% by weight or more and a critical shear rate of 0.5 (l/sec) or less, said resin composition obtained by the melt-blending having a critical shear rate of 10 (l/sec) or less; and a process for producing the resin-coated paper. The resin-coated paper is good in the molding processability of the resin layer, is excellent in the adhesion between the resin layer and the base paper, and contains only a small amount of a gel formed.

摘要： A photographic support comprising a paper substrate and the resin layers formed on both sides thereof, each of the resin layers being made of a resin composition comprising a polyethylene resin, wherein the difference in thickness between the resin layer on the side on which a photographic layer is to be provided and the resin layer on the opposite side is 3 .mu.m or greater, and the polyethylene resin in the resin layer on the side opposite from the photographic layer is a compounded resin prepared by melting and mixing a specified number of parts by weight of a specific low-density or medium-density polyethylene resin and a specified number of parts by weight of a specific high-density polyethylene resin. This resin-coated paper type photographic support has good adhesion between the base paper and the resin layer on the side opposite from the photographic layer, excellent in qualities such as anticurl properties, cutting properties and capable of high-speed production.
