    • A silver halide printing paper is disclosed, which is improved in a remaining curl. The support of the photographic paper comprises a support having a paper substratum, being coated over to the both sides thereof with a polyolefin resin, and has a Taber stiffness value of from 1.0 to 3.0 in machine directioin. At least one silver halide emulsion layer is coated on one side and a hydrophilic colloidal backing layer is coated on the other side of the support. The silver halide emulsion layer contains a polyhydric alcohol in an amount of from 5 to 40% by weight to an amount by weight of the gelatin binder forming the emulsion layer and an alkyl acrylate polymer latex in an amount of from 30 to 80% by weight thereto. A total amount of gelatin coated over to the emulsion layer side of said support is not more than 4.0 g/m², and a total amount of gelatin coated over to the backing layer side of said support is not more than 2.0 g/m².
