Abstract
Abstract A silver halide color photographic material comprising a support having thereon at least a silver halide emulsion layer containing a hydrophobic phenolic or naphtholic cyan dye forming coupler together with a 2-(2'-hydroxyphenyl)benzotriazole compound. The color photographic material provides a cyan dye image having improved moisture resistance and high fastness to heat.

The silver halide color photographic material of claim 1, in which said 2-(2'-hydroxyphenyl)benzotriazole compound is represented by general formula (I): ##STR14## wherein R 1 , R 2 , R 3 , R 4 , and R 5 , which can be the same or different, each represents a hydrogen atom, a halogen atom, a nitro group, a hydroxyl group, an alkyl group, an alkenyl group, an alkoxy group, an acyloxy group, an aryl group, an aryloxy group, an alkylthio group, an arylthio group, a monoalkylamino group, a dialkylamino group, or a heterocyclic group, and R 4 and R 5 may combine to form a 5-membered or 6-membered carbon atom containing ring.
Claim 4
Dependent Claim
95 words
The silver halide color photographic material of claim 2, in which said 2-(2'-hydroxyphenyl)benzotriazole compound is represented by general formula (II): ##STR15## wherein R 1 and R 2 each represents a hydrogen atom, a halogen atom, a nitro group, a hydroxyl group, an alkyl group, an alkenyl group, an alkoxy group, an acyloxy group, an aryl group, an aryloxy group, an alkylthio group, an arylthio group, a monoalkylamino group, a dialkylamino group, or a heterocyclic group and R' 4 represents a halogen atom, an alkyl group, an alkoxy group, an aryl group, or an aryloxy group.
Claim 5
Dependent Claim
122 words
The silver halide color photographic material of claim 1, in which said hydrophobic phenolic or naphtholic cyan coupler is represented by the following general formulae (III) or (IV): ##STR16## wherein R 6 , R 7 , R 8 and R 9 , which can be the same or different, each represents a hydrogen atom, a halogen atom, a cyano group, an alkyl group, an alkoxy group, an aryl group, an aryloxy group, a heterocyclic group, an amino group, a carbonamido group, a sulfonamido group, a sulfamoyl group, or a carbamoyl group; and at least one of said R 6 to R 9 is substituted with a ballast group; and X and Y each represents a hydrogen atom or a coupling releasable group.
Claim 6
Dependent Claim
33 words
The silver halide color photographic material of claim 1, in which said silver halide emulsion layer containing the 2-(2'-hydroxyphenyl)benzotriazole compound and the hydrophobic phenolic or naphtholic cyan coupler is a red-sensitive emulsion layer.
Claim 7
Dependent Claim
79 words
The silver halide color photographic material of claim 1, in which said color photographic material comprises a support having thereon at least three silver halide emulsion layers sensitive to different wavelength regions and said three silver halide emulsion layers are a blue-sensitive silver halide emulsion layer containing a yellow coupler, a green-sensitive silver halide emulsion layer containing a magenta coupler, and a red-sensitive silver halide emulsion layer containing the 2-(2'-hydroxyphenyl)benzotriazole compound and the hydrophobic phenolic or naphtholic cyan coupler.
Claim 8
Dependent Claim
27 words
The silver halide color photographic material of claim 1, in which said 2-(2'-hydroxyphenyl)benzotriazole compound is present in the silver halide emulsion layer as an emulsified dispersion thereof.
Claim 9
Dependent Claim
24 words
The silver halide color photographic material of claim 6, in which said color photographic material further includes a filter layer containing the 2-(2'-hydroxyphenyl)-benzotriazole compound.
Claim 10
Dependent Claim
26 words
The silver halide color photographic material of claim 2, in which said silver halide emulsion layer contains at least two compounds represented by general formula (I).
Claim 11
Dependent Claim
49 words
The silver halide color photographic material of claim 1, in which the amount of the 2-(2'-hydroxyphenyl)-benzotriazole compound in said silver halide emulsion layer is about 0.01 to 3 parts by weight per part by weight of the hydrophobic phenolic or npahtholic cyan coupler in said silver halide emulsion layer.
Claim 12
Dependent Claim
28 words
The silver halide color photographic material of claim 2, in which at least one of R 4 and R 5 in general formula (I) is a halogen atom.
Claim 13
Dependent Claim
20 words
The silver halide color photographic material of claim 4, in which said hydrophobic phenolic cyan coupler is a 2-acylamino-5-methyl-6-chlorophenolic compound.
Claim 14
Dependent Claim
54 words
In a silver halide photographic material comprising a support having thereon at least one silver halide emulsion layer containing a phenolic or naphtholic cyan dye-forming coupler and at least one 2-(2'-hydroxyphenyl)-benzotriazole compound, the improvement which comprises said cyan coupler being hydrophobic and being incorporated in said silver halide emulsion layer with said benzotriazole compound.
Claim 15
Dependent Claim
54 words
In a silver halide photographic material comprising a support having thereon at least one silver halide emulsion layer containing a phenolic or naphtholic cyan dye-forming coupler and at least one 2-(2'-hydroxyphenyl)-benzotriazole compound, the improvement which comprises said cyan coupler being hydrophobic and being incorporated in said silver halide emulsion layer with said benzotriazole compound.
