Abstract
A silver halide color photographic light-sensitive material in roll form comprises a support, and provided thereon, a silver halide emulsion layer and, on the side of the support opposite the silver halide emulsion layer, a backing layer containing gelatin and a hardener, wherein the backing layer has a degree of swelling of 250% or less represented by the following equation: Degree of swelling=[(A-C)/(B-C)].times.100.

A silver halide color photographic light-sensitive material in roll form comprising a support, and provided thereon, a silver halide emulsion layer and, on the side of the support opposite the silver halide emulsion layer, a backing layer containing gelatin and a hardener, the backing layer having a degree of swelling of 250% or less represented by the following equation:
- Degree of swelling = [ (A - C) / (B - C) ] .times. 100
- wherein A is the weight (in grams) of 10 cm.sup.2 of the photographic light sensitive material after (i) adhering water-proof tape on the backing layer, (ii) removing the silver halide emulsion layer with a bleaching agent, (iii) peeling off the water-proof tape, (iv) conditioning the resulting material at 23.degree. C. and 55% RH for 1 day, (v) dipping the conditioned material in a color developer at 38.degree. C. for 3 minutes, and (vi) wiping off the color developer from the material;
- B is the weight of the material after further conditioning at 23.degree. C. and 55% RH for 1 day;
- and C is the weight of the material after removing the backing layer with a bleaching agent and further conditioning the resulting material at 23.degree. C. and 55% RH for 1 day.
