The side of the paper which is destined to receive the photographic layer is coated with two resin layers lying one on top of the other, i.e., a first layer lying on the paper and the second layer arranged to contact the photographic layer. Only the second layer contains stabilizers and/or antioxidants, these being preferably in the range 0.03 to 2.0% by weight.
