Abstract: A direct positive silver halide light-sensitive color photographic material comprising, on a support, (1) at least three light-sensitive silver halide emulsion layers containing internal latent image-type light-sensitive silver halide grains, (2) specific sensitizing dyes having formulas [I], [II] and [III], respectively defined in the specification, and (3) at least one anti-irradiation compound selected from the group consisting of those compounds having formulas [IV], [V] and [VI], respectively defined in the specification, is disclosed.

Abstract: A direct positive silver halide photographic material with an internal latent image-type silver halide emulsion layer that provides a direct positive image by a fogging treatment (for example, an overall exposure, or surface developing treatment in the presence of a fogging agent) after imagewise exposure. The silver halide particles which form the emulsion layer consist essentially of a core portion made of silver halide and having been chemically sensitized or doped with metal ions. There are provided a plural number of shell portions made of silver halide containing silver chloride. The chloride content of an inner shell adjacent to the outmost shell of the particles has a smaller amount of chloride content than that of the outermost shell. The photographic material is used by first imagewise exposing it to light, effecting overall fogging treatment on the silver halide particles and processing the exposed photographic material to produce the image.

Abstract: A direct positive light-sensitive silver halide photographic material having at least one silver halide emulsion layer containing at least two kinds of internal latent image type silver halide grains not previously fogged and having the same spectral sensitivity, and capable of obtaining a direct positive image by effecting surface development while applying and/or after applying overall exposure after imagewise exposure; wherein said at least two kinds of internal latent image type silver halide grains have different sensitivity from each other and at least one of silver halide grains having lower sensitivity is desensitized with use of an organic or inorganic desensitizer, and a method of use of the direct positive light-sensitive silver halide photographic material for carrying out development at a higher temperature.

Abstract: The present invention relates to a process for forming a direct positive color image comprising(a) imagewise exposing a direct positive photosensitive silver halide color photographic material to light to yield an imagewise exposed material, said photographic material having a support and at least one silver halide emulsion layer thereon, said emulsion layer containing a coupler and internal latent image type silver halide crystals whose surfaces have not been fogged prior to said imagewise exposure, and(b) uniformly exposing to light the entire surface of said imagewise exposed photographic material before or during a development step and in the presence of a substance of Formula IV, a compound of formula I and a color-developing agent consisting of aromatic primary amino compounds selected from the group consisting of N-methyl-aminophenol, 4-amino-3-methyl-N-ethyl-N-(-methanesulfonamidoethyl) aniline,4-amino-3-methyl-N-ethyl-N-(-hydroxyethyl) aniline, 4-amino-3-methyl-N, N-diethyl-p-phenylenediamine, and 4-

Abstract: A process for developing an image-wise exposed light-sensitive silver halide color photographic material comprising developing said material with a solution containing a specified concentration range of bromide ion in the presence of at least one of certain active point substitution type yellow couplers.
