摘要

A novel support for used in photographic printing paper is provided comprising a base paper covered on both sides with polyolefin coating, said base paper being one which has undergone calender treatment between a metallic roll and a synthetic resin roll and then between a metallic roll and another metallic roll. In a preferred embodiment, the calender treatment is performed at the final finishing process. The calender treatment between the metallic roll and the synthetic resin roll is performed in such a manner that the density of the paper is increased to from 0.70 to 1.00 g/cm<3> and the calender treatment between the metallic rolls is performed in such a manner that the density of the paper is increased to from 1.00 to 1.20 g/cm<3>. The material of the synthetic resin roll is selected from the group consisting of urethane resin, ebonite resin, nylon resin, aramide resin and isocyanurate resin. The hardness of the synthetic resin roll is from 60 to 90, preferably 75 to 90 in terms of Shore hardness. The surface temperature of the synthetic resin roll and the metallic rolls are in the range of 30 to 150 DEG C, preferably 50 to 100 DEG C, and 50 to 250 DEG C, preferably 70 to 150 DEG C, respectively.
