摘要： PURPOSE:To improve the color reproducibility of a sensitive material by incorporating a specified compd. in the emulsion layer contd. in the sensitive material. CONSTITUTION:The compd. (for example, the compd. shown by formula I) capable of being released a compd. (its precursor) which scavenges a reaction product obtd. by allowing it to react with the oxidant of a developing main agent, is incorporated in the silver halide emulsion layer contd. in the sensitive material. The positive image is formed by developing the sensitive material with a color developing solution in the presence of a fogging agent. At that time, the developing agent (A) contains preferably hydroxylamines shown by formula II and/or the phosphoric acid compd. In formula I, Coup is a coupler residual group, TIME is a timing group, Sc is a scavenger (or its precursor), (l) is 0 or 1. In the formula II, R and R are each hydrogen atom or alkyl group.

摘要： PURPOSE:To sufficiently increase the max. density in particular while lowering the min. density to the level at which there are no problems in practicable use and to obtain a good positive image by incorporating at least one coupler into the title material and incorporating a phosphoric acid compd. into a color developing soln. CONSTITUTION:At least one kind of the couplers expressed by the formula I is incorporated into the above-mentioned material and the phosphoric acid compd. is incorporated into the color developing soln. In the formula, Z denotes a nonmetallic atom group necessary for forming a niterogenous heterocyclic ring and the ring formed by Z includes the ring having a substituent; X denotes a hydrogen atom or substituent which can be eliminated by reaction with the oxidant of the color developing agent. Further, R denotes a hydrogen atom or substituent. The max. density in particular is thereby increased and the good positive image is obtd.. while the min. density is maintained at the level at which there are no problems in practicable use.

摘要： PURPOSE:To thin the photographic constituting layer without rising fog by constituting the binder contd. in a nonphotosensitive layer of a gelatin, and by incorporating a specified yellow filter dyestuff in the nonphotosensitive layer. CONSTITUTION:In the titled materials, the binder contd. in the nonphotosensitive layer is composed of the gelatin having an isoelectric point of >=5.5, and the nonphotosensitive layer contains the yellow filter dyestuff which can decolor by processing. Namely, as the nonphotosensitive layer which fulfills the function of a yellow filter layer is composed of the gelatin having the isoelectric point of >=5.5 and contains the yellow filter dyestuff, the fog in the emulsion layer does not rise differing from the case of using a colloidal silver, whereby the nonphotosensitive layer is not necessary to separate from the emulsion layer by an intermediate layer. Thus as the intermediate layer is needless, the photographic constituting layer can reduce the thickness by that of the intermediate layer, thereby improving the sharpness of the titled material.

摘要： PURPOSE:To expand a latitude of the title material for photographic fog by forming at least three layers contg. a specified sensitizing dye in each layer, and incorporating also a specified compd. into said layers. CONSTITUTION:The title material has, for example, at least three layers contg. a sensitizing dye as expressed by formula I in each layer, and contg. also at least one compd. selected from a group of compds. expressed by formula II. In formula I, each Z1 and Z2 is an atomic group necessary for forming a benzothiazole ring, naphthothiazole ring, etc.; each R1 and R2 is a substituted or unsubstituted alkyl group; X1 is an anion. In formula II, Y is O or S; Q is an atomic group necessary for forming a pyrazolone ring, isoxazolone ring, etc.; each R and R is an alkyl group; M is H or cation; each L -L is a methine group. By this constitution, the photographic fog latitude of a direct positive silver halide color photographic sensitive material is expanded.

摘要： PURPOSE:To adjust the exposure illuminance, illuminance distribution, and spectral distribution of a fog light by changing the light transmission quantity of a photoconductive member so that the intensity of incident light is increased in the carrying direction of the photosensitive face of internal latent image type silver halide photographic sensitive materials. CONSTITUTION:In a stage where a sensitive material 1 is carried in the direction of an arrow by carrying rolls 10 and 10', the sensitive material 1 is exposed to the light transmitted through a filter A and is exposed next to the light transmitted through a filter B. Since the filter density of the filter A is higher than that of the filter B, fog exposure is given where the intensity of the light incident on the photosensitive face of the sensitive material 1 is increased stepwise. The manner of setting of the intensity of incident light in the carrying direction of the photosensitive face of the sensitive material 1 is calculated in accordance with the correct exposure in relationsto the intensity of light and the running speed. Thus, stable fog exposure is performed easily to obtain good positive images finally.

摘要： PURPOSE:To improve stability of processability by incorporating at least 2 kinds of internally latent image type silver halide grains different in average grain diameter in a silver halide emulsion layer and a compound capable of reacting with the oxidation product of a color developing agent and releasing a development inhibitor or its precursor in one of photographic constituent layers. CONSTITUTION:The silver halide emulsion layer contains at least 2 kinds of internally latent image type silver halide grains different in average grain diameter, and at least one of photo graphic constituent layers contains at least one of compounds each capable of reacting with the oxidation product of a color developing agent and releasing a development inhibitor or its precursor (DIR compound). The internally latent image type silver halide grains, prefer ably, contain 60wt% grains within + or -20% of the average grain diameter, and preferable DIR compounds can be represented by formula (I) Coup-Inhibitor and (II) Coup-TIME-Inhibitor in which Coup is a coupler component capable of coupling with the oxidation product of a color developing agent, and Inhibitor is a group to be released by the coupling reaction with the oxidation product of a color developing agent, and suppresses the development of silver halide, thus permitting the obtained photosensitive material to have good stable processability and to obtain a photographic image smooth in gradation and good in sharpness with high reproducibility.
