Title:
SILVER HALIDE PHOTOGRAPHIC SENSITIVE MATERIAL AND IMAGE FORMING METHOD
Document Type and Number:
Japanese Patent JPH1195364
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a photographic sensitive material capable of being easily and rapidly processed and small in fluctuation of toe gradation during storage with the lapse of time by incorporating a specified compound and a specified noncolor-developing water-insoluble compound in at least one of photosensitive layers and nonphotosensitive layers formed on a support. SOLUTION: At least one of the photosensitive layers and the nonphotosensitive layers formed on the support contains the compound represented by formula I: R<1> -NHNH-X-R<2> and at least one of them contains the noncolordeveloping and water-insoluble compound represented by formula II, and in formulae I and II, R<1> is an aryl or heterocyclic group; R<2> is an alkyl or alkenyl or alkynyl or heterocyclic group or the like; L is a -SO2 -, -CO-, or -COCO- group or the like; X is an electron withdrawing group having a Hammett's substituent constant σp, of >=0.25; Y is an alkylene group having 1-4C in the main chain; and Z is a nonmetallic atomic group necessary to form a 5-7-membered nonaromatic hetero ring together with the N atom.
