Abstract
A silver halide emulsion having a silver chloride content of 90 mol % or more which has been chemically sensitized with a compound capable of releasing an AuICh− ion is described, wherein grains of the silver halide contain in the shell portion thereof 0.01 to 0.50 mol % of silver iodide per mol of the total silver, with Ch representing S, Se or Te.

A silver halide emulsion having a silver chloride content of 90 mol % or more which has been chemically sensitized with a compound capable of releasing an AuICh− ion, wherein grains of the silver halide contain in the shell portion thereof 0.01 to 0.50 mol % of silver iodide per mol of the total silver, with Ch representing S, Se or Te.
A silver halide emulsion having silver chloride content of 90 mol % or more which has been chemically sensitized with at least one compound selected from the group consisting of the gold-chalcogen compounds represented by the following general formula (PF1), (PF2), (PF3) or (PF4), wherein grains of the silver halide contain in the shell portion thereof 0.01 to 0.50 mol % of silver iodide per mol of the total silver:
- 122
- wherein Ch represents an S atom, an Se atom or a Te atom, L1 represents a compound capable of coordinating with gold via an N atom, an S atom, an Se atom or a Te atom, n represents 0 or 1, A1 represents O, S or NR4, R1 to R4 each represents a hydrogen atom or a substituent, or R3 may form a 5- to 7-membered ring together with R1 or R2, X1 represents O, S or NR5, Y1 represents an alkyl group, an alkenyl group, an alkynyl group, an aryl group, a hetero ring group, OR6, SR7, or N(R8)R9, R1 to R9 each represents a hydrogen atom, an alkyl group, an alkenyl group, an alkynyl group, an aryl group or a hetero ring group, X1 and Y1 may be bound to each other to form a ring, R10, R10 and R11 each independently represents a hydrogen atom or a substituent, with at least one of R10 and R10′ representing an electron attractive group, W1 represents an electron attractive group, and R12 to R14 each represents a hydrogen atom or a substituent, with W1 and R12 optionally being bound to each other to form a cyclic structure.
A silver halide color photographic light-sensitive material comprising a support having provided thereon photograph-constituting layers containing at least one yellow image-forming silver halide emulsion layer, at least one magenta image-forming silver halide emulsion layer, at least one cyan image-forming silver halide emulsion layer and at least one light-insensitive hydrophilic colloid layer, wherein the silver halide emulsion in at least one of the silver halide emulsion layers is a silver halide emulsion having a silver chloride content of 90 mol % or more which has been chemically sensitized with a compound capable of releasing an AuICh− ion, wherein grains of the silver halide contain in the shell portion thereof 0.01 to 0.50 mol % of silver iodide per mol of the total silver, with Ch representing S, Se or Te.
An image-forming method which comprises conducting scanning exposure of a silver halide color photographic light-sensitive material by a laser light beam modulated based on image information with an exposure period per pixel of shorter than 10−4 second, then conducting development processing, said silver halide color photographic light-sensitive material comprising a support having provided thereon at least one blue-sensitive silver halide emulsion layer, at least one green-sensitive silver halide emulsion layer and at least one red-sensitive silver halide emulsion layer, wherein at least one of the blue-sensitive silver halide emulsion layer, the green-sensitive silver halide emulsion layer and the red-sensitive silver halide emulsion layer contains a silver halide emulsion having a silver chloride content of 90 mol % or more which has been chemically sensitized with a compound capable of releasing an AuICh− ion, wherein grains of the silver halide contain in the shell portion thereof 0.01 to 0.50 mol % of silver iodide per mol of the total silver, with Ch representing S, Se or Te.
