Silver halide photographic material and method of processing the same

Abstract

Disclosed is a silver halide photographic material for medical use, in which the coated amount of silver per surface of the support is 2.8 g/m.sup.2 or less, the silver halide grains in the coated silver halide emulsion layer have a silver chloride content of 10 to 50 mol %, they contain 10.sup.-8 mol or more, per mol of silver, of an iridium compound and they have been spectrally-sensitized to be sensitive to rays of from 600 to 700 nm wavelength range. The material may be processed by rapid processing and has a high sensitivity and high covering power. Also disclosed is a silver halide photographic material for laser exposure, in which the emulsion contains 10.sup.-8 mol or more, per mol of silver, of an iridium compound and is spectrally-sensitized with a sensitizing dye of formula (III): ##STR1## where V.sub.1, V.sub.2, V.sub.3, V.sub.4, V.sub.5, V.sub.6, V.sub.7 and V.sub.8 each represent a hydrogen atom or a monovalent substituent, and they satisfy the following conditions: where f value of Vk (k=1 to 8) is Vkf, A.sub.1 =V.sub.1 f+V.sub.2 f+V.sub.3 f+V.sub.4 f, and A.sub.2 =V.sub.5 f+V.sub.6 f+V.sub.7 f+V.sub.8 f; then A.sub.1 <1.63, or A.sub.2 <1.63; R.sub.1 and R.sub.2 each represent a substituted or unsubstituted alkyl group; L.sub.1, L.sub.2 and L.sub.3 each represent a substituted or unsubstituted methine group; M.sub.1 represents a charge neutralizing pair ion; and m.sub.1 is a number of 0 or more, which is necessary for neutralizing the charge of the molecule. This has high sensitivity and may be processed by ultra-rapid processing system to result in little residual color in the processed material.
