PHOTOGRAPHIC SUBSTRATE WITH BACKING LAYER

摘要

PROBLEM TO BE SOLVED: To obtain a photographic substrate having improved electrostatic chargeability. SOLUTION: The photographic substrate has a substrate and a backing layer consisting of at least one inner layer and the outermost layer on one face of the substrate. The inner layer is formed by coating with a coating composition containing an organic binder, an antistatic agent and a matting agent. The thickness of the outermost layer is smaller than the projection height of the matting agent that projects from the surface of the inner layer and the absolute value of the logarithm logSR/Er of the ratio of the surface resistance SR to the inner resistance ER is 0-3.
