Estimating the term…
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.
