The influence of a chemical modification (hardening) on 
the behavior of photographic gelatins at an interface has been investigated. 
It has been established, using the Langmuir monolayer method, that 
the properties of the surface layers of a modified gelatin change 
at the water-air interface and the depth of modification influences 
the surface activity of the gelatin. The surface properties of gelatin 
gels were investigated by the method of wetting depending on the hardener 
nature and the gelatin molecular-mass composition. It has been established 
that the hydrophilicity of gelatin gels increases with increase in 
the content of -chains and the surface of gelatin gels 
is additionally hydrophilized as a result of their modification.
