Patent ID: 7122298

Claim:
A silver halide photographic photosensitive material, comprising a support and at least one photosensitive silver halide emulsion layer on the support, wherein the silver halide photographic photosensitive material comprises at least one layer comprising an emulsion containing at least one surfactant represented by the following formula (I), and the silver halide photographic photosensitive material contains a substantially non-color-forming photosensitive emulsion layer: (R 1 —L) n -J-(A) m (I), wherein A represents an acid group selected from the group consisting of a sulfonic acid, a phosphoric acid, a carboxylic acid and metal salts thereof; R 1 represents an aliphatic group including as a partial structure thereof an aliphatic group whose main chain has at least 6 carbon atoms; L represents a divalent group; J represents a linking group, having a valence of n plus m, which links R 1 —L and A; n represents a natural number of from 1 to 6; and m represents a natural number of from 1 to 3, wherein, when n represents 2 or more, plural (R 1 —L) groups present may be the same as each other or different from one another, wherein, when m represents 2 or more, plural A groups present may be the same as each other or different from one another; a sum of carbon atoms of R 1 (when n is 2 or more, a sum of the carbon atoms in all R 1 groups) is 17 or more; and a value obtained by dividing a molecular weight of the surfactant (in the case of a metal salt, the molecular weight obtained by substituting the metal atom with a hydrogen atom) represented by the formula (I) by m is 430 or more.
