Silver halide photosensitive material

A silver halide photographic material has provided on a support a non-light-sensitive surface layer which contains an organic polymer represented by formula (I) and having a mean grain size of 1.0 .mu.m or more, the polymer being produced by suspension polymerization: ##STR1## wherein A is a repeating unit obtained by polymerization of at least one monomer having two or more copolymerizable ethylenic unsaturated groups; B is a repeating unit obtained by polymerization of at least one monomer having one copolymerizable ethylenic unsaturated group; and x, y and z each represents a weight percentage, x is a number of from 1 to 40, y is a number of from 30 to 99 and z is a number of from 0 to 65. The material has good vacuum contact adhesiveness in contact exposures, and the transparency of the processed material is good.

Silver halide photographic material

Disclosed is an autopositive silver halide photographic material which comprises at least one silver halide emulsion layer, characterized in that said emulsion layer or at least one other hydrophilic colloid layers contains at least one compound selected from the group consisting of compounds represented by the following general formulas (1), (2) and (3): ##STR1## wherein R.sub.1 represents hydrogen atom or an alkyl group; and R.sub.2, R.sub.3 and R.sub.4 each represents hydrogen atom, a halogen atom, an alkyl group or an alkoxy group; ##STR2## wherein R.sub.5 represents hydrogen atom or an alkyl group; and R.sub.6 and R.sub.7 each represents hydrogen atom, an alkyl group, a halogen atom or an aryl group; ##STR3## wherein R.sub.8 represents a lower alkylene group; X represents a halogen atom, nitro group, hydroxy group, a cyano group, a lower alkyl group, a lower alkoxy group, ##STR4## or --SO.sub.3 M; R.sub.12 represents hydrogen atom, --OM, a lower alkyl group, a lower alkoxy group or ##STR5## R.sub.13 and R.sub.14 may be the same or different groups and each represents hydrogen atom, a lower alkyl group, --COR.sub.17 or --SO.sub.2 R.sub.17 ; R.sub.15 and R.sub.16 may be the same or different groups and each represents hydrogen atom or a lower alkyl group; R.sub.17 represents a lower alkyl group; M represents hydrogen atom, an alkali metal or an atomic group required for forming a monovalent cation; and n represents 0 or an integer of 1 to 5.

A method for producing a silver halide photographic material which comprises the steps of:

Method for the manufacture of silver halide photographic materials

A silver halide photographic material composed of a polyester film support having thereon at least one hhydrophilic colloid layer containing a polymer latex; and between the support and the hydrophilic colloid layer a layer containing a vinylidene chloride copolymer core-shell latex; at least one hydrophilic colloid layer of the material being a light-sensitive silver halide emulsion layer. The photographic material has superior dimensional stability after processing.

Silver halide photographic material containing an interlayer containing

A silver halide photographic light-sensitive material having on a support at least one light-sensitive silver halide emulsion layers and at least one light-insensitive upper layers on the emulsion layer, in which at least one of said light-insensitive upper layers contains a polymer latex having a glass transition point of at least 20.degree. C. and the said at least one light-insensitive upper layer and/or at least one other of said at least one light-insensitive upper layer(s) contains a polymer latex having a glass transition point of lower than 20.degree. C. In the silver halide photographic light-sensitive material, at least one of the light-insensitive upper layers can also have a melting time which is longer than that of the light-sensitive silver halide emulsion layer. The silver halide photographic light-sensitive material has high sticking resistance and improved layer strength under low humidity conditions.
