Silver halide photographic light-sensitive material

Abstract

A silver halide photographic light-sensitive material is disclosed. The silver halide emulsion layer of the light-sensitive material is sensitized in infrared region of the spectrum by a cationic di- or tri-carbocyanine sensitizing dye and a compound represented by formula I, II, or III; ##STR1## The light-sensitive material is improved in stability of the coating solution of the silver halide emulsion for standing during in its production process and also improved in stability for prolonged storage after production.

What is claimed is: 
     
       1. A silver halide photographic light-sensitive material comprising a support having thereon (i) a silver halide emulsion layer being spectrally sensitized with at least one selected from a cationic di-carbocyanine and a cationic tri-carbocyanine sensitizing dye; and a phenol resin formed by condensation of a phenol and an aldehyde; and (ii) a compound contained in at least one of said silver halide emulsion layer and an hydrophilic colloid layer other than said silver halide emulsion layer, which is provided on the side of said support on which said silver halide emulsion layer is provided, said phenol resin having a polymerization degree in the range of 2 to 10,000 and being present in amount of 1×10 -4  to 100 g per mole of silver halide contained in said silver halide emulsion, and being selected from the group consisting of: ##STR18## and said compound contained in at least one of said silver halide emulsion layers and a hydrophilic colloid layer other than said silver halide emulsion layer being present in an amount of 5 mg to 5 g per mole of silver halide contained in the silver halide emulsion layer and being selected from the group consisting of: ##STR19## (II-1) 6-Amino-purine ribocide (II-2) 6-Chloro-purine ribocide (II-3) 6-Methylamino-purine ribocide   (II-4) 5'-Phosphoric acid-6-amino-purine ribocide   (II-5) 5'-Phosphoric acid-6-chloro-purine ribocide   (II-6) 5'-Phosphoric acid-6-amino-purine ribocide   (II-7) 5'-Hydroxymethyl-6-methylamino-purine ribocide   (II-8) 5'-Methyl-6-amino-purine ribocide   (III-1) 6-Oxy-purine ribocide   (III-2) 2-Amino-6-oxy-purine ribocide   (III-3) 5'-Phosphoric acid-6-oxy-purine ribocide.
