A photographic material comprising hydrophobic support having thereon
- at least one silver halide emulsion layer,
- a first subbing layer composed of a copolymer of a dienic monomer,
- and a second subbing layer comprising a hydrophilic layer containng gelatin and water-soluble methyl cellulose having a degree of substitution of 0.5 to 2.6 or gelatin and water-soluble polyvinyl alcohol having a degree of hydrolysis of 60 to 97 mole % on the first subbing layer,
- wherein said copolymer, said methyl cellulose and said polyvinyl alcohol are added in amounts sufficient to prevent blocking of photographic materials.
