CONSTITUTION:This silver halide photographic sensitive material has at least one silver halide emulsion layer of a silver chloride emulsion prepd. in the presence of 1X10 -1X10 mol water soluble rhodium salt basing on 1mol silver halide or a silver chlorobromide emulsion having >=80mol% silver chloride content. The emulsion layer or at least one of other hydrophilic colloidal layers contains a dye compound represented by the formula (where R1 is alkyl, alkoxy or the like, Q is sulfoalkyl or the like, R2 is H, alkyl or the like and each of R3 and R4 is substituted alkyl but R1, R3 and R4 are not simultaneously methyl). The sensitive material can be handled in an environment which can be practically called daylight.

摘要： PURPOSE:To obtain the titled material having a super contrasity by incorporating a tetrazolium compd. And a dyestuff having a peak of abosrption in 400-550nm to an emulsion layer and/or an another hydrophilic colloidal layer, and by specifying ratio of sensitivity to >=30 the at 360nm to at 400nm. CONSTITUTION:As the tetrazolium compd., either a diffusion type tetrazolium compd. or a nondiffusion type tetrazolium compd. may be used in the case that the silver halide is used to the titled material. When the nondiffusion tetrazolium compd. is used to the titled material, the image having a more contrasty is obtd. The tetrazolium compd. is preferable to use 1X10 -1X10 mol per 1mol of the silver halide. As the hyestuff having a peak in 400-550nm has a main absorption over the visible wavelength range of the intrinsic photosensitive wavelength range of the silverhalide emulsion used, it makes easy to handle it under a day light room. Thus, the titled material having a good super contrasty is obtd.

摘要： PURPOSE:To obtain a silver halide photographic sensitive material which can be handled in a light room without impairing the effect of a hydrazine deriv. for increasing the contrast, and providing superhigh contrast photographic charac teristic by the treatment with a developing solution having high sensitivity and stability by providing a photosensitive material comprising a silver halide layer contg. a specified amt. of Rh salt and silver chlorobromide particles contg. below 5 mol% AgBr, and an emulsion and/or other hydrophilic colloid layer contg. a hydrazine deriv. and a dye having a peak in a range of wavelength between 400 and 550 nm, adjusting thus the sensitivity ratio at 360 nm to 400 nm to >=30. CONSTITUTION:A photosensitive material contains 1X10 -5X10 mole Rh salt per 1 mole Ag, has at least one layer of silver halide emulsion comprising silver chlorobromide particles contg. below 5 mol% AgBr. The material contains also a hydrazine deriv. and a dye having a peak between 400 and 550 nm wavelength in the emulsion layer and/or other hydrophilic colloid layer. The sensitivity ratio (S360/S400) at 360 nm to 400 nm is >=30. Thus, a photosensitive material having high sensitivity and superior safelight property is provided.

摘要： PURPOSE:To prevent the hindrance of hard contrasting by a hydrazine deriv. by providing at least one non-photosensitive layer contg. a specific compd. to the upper part of an emulsion layer. CONSTITUTION:At least one non-photosensitive layer contg. at least one kind of the compd. expressed by formulas (I), (II) is provided to the upper part of the emulsion layer of a silver halide photosensitive material having at least one silver halide emulsion layer on a base and contg. The hydrazine deriv. in the emulsion layer or other hydrophillic colloid layer. The compd. used here can be synthesized by the condensation of an aldehyde compd. and active methylene compd. A solvent having the properties to dissolve the starting material is useful for the condensation reaction but there are many reactions which progress even if the starting material does not dissolve. The suitable solvent is exemplified by alcohol, etc.
