Silver halide photographic material and method for forming an image
摘要:
A negative silver halide photographic material composed of a support having thereon at least one chemically sensitized silver halide emulsion layer at least one hydrophilic colloidal layer containing a hydrazine derivative and a compound having substantially all absorption maxima outside the visible light region represented by formula (I):
wherein Z¹¹ and Z¹² each represents a non-metallic atomic group necessary for completing a substituted or unsubstituted heterocyclic ring selected from benzoxazole, benzothiazole, benzoselenazole, naphthoxazole, naphthothiazole, naphthoselenazole, thiazole, thiazoline, oxazole, selsnazole, selsnazoline, pyridine, benzimidazole, and quinoline; R¹¹ and R¹² each represents a substituted or unsubstituted alkyl group, provided that at least one of them is substituted with an acid radical; X represents a counter ion necessary for charge balance; and n is 0 or 1.
The photographic material exhibits high sensitivity and provides an image having high contrast and high density, with neither black pepper nor residual color in the non-image area.
