ABSTRACT:
The present invention provides a siliver halide photographic photosensitive material which comprises a base, at least a silver halide emulsion layer provided on the base and at least a back coat layer comprising a gelatin containing a polymer mainly composed of styrenesulfonic acid provided on another side of the base wherein said back coat layer additionally contains a surface active agent represented by the following formula [I] and is hardened with a triazine. ##STR1## whererin n is a natural number of 1-20, M represents a hydrogen atom or an alkali metal, and R represents an alkyl group of 5-15 carbon atoms, or ##STR2## in which R.sub.1 represents an alkyl group of 5-15 carbon atoms and R.sub.2 represents an alkyl group of 1-3 carbon atoms, a hydrogen atom or a halogen atom. Said back coat layer is excellent in antistatic properties, adhesion to a base and drying properties.
