Abstract

Abstract Color photographic light-sensitive material comprising, on a reflective support, at least one light-sensitive silver halide emulsion layer containing a dye-forming coupler and a non- light-sensitive layer provided on said light-sensitive silver halide emulsion layer in this order from said reflective support is stabilized against color deterioration from light or static electricity when said non-light-sensitive layer contains a benzotriazole derivative having the following wherein R 1 and R 2 are each alkyl, alkoxy or alkenyl having not less than 4 carbon atoms, or aryl or aryloxy, and a compound having the formula [II] or [III]: wherein R 4 and R 5 are each alkyl, aryl or aralkyl having not less than 5 carbon atoms; wherein R 6 , R 7 and R 8 are each alkyl having not less than 5 carbon atoms, or aryl.

Claims Analysis

Total Claims: 6
Claim 1
Independent Claim 125 words
A color photographic light-sensitive material comprising, on a reflective support, at least one light-sensitive silver halide emulsion layer containing a dye-forming coupler and a nonlight-sensitive layer provided on said light-sensitive silver halide emulsion layer in this order from said reflective support, characterized in that the nonlight - sensitive layer contains a benzotriazole derivative having the formula wherein R1 and R2 are each alkyl, alkoxy or alkenyl, having not less than 4 carbon atoms, or aryl or aryloxy, and a compound having the formula [II]or [III]: wherein R 4 and R 5 are each alkyl, aryl or aralkyl having not less than 5 carbon atoms; wherein R 6 , R 7 and R 8 are each alkyl having not less than 5 carbon atoms or aryl.
Claim 2
Dependent Claim 125 words
A color photographic light-sensitive material comprising, on a reflective support, at least one light-sensitive silver halide emulsion layer containing a dye-forming coupler and a nonlight-sensitive layer provided on said light-sensitive silver halide emulsion layer in this order from said reflective support, characterized in that the nonlight - sensitive layer contains a benzotriazole derivative having the formula wherein R1 and R2 are each alkyl, alkoxy or alkenyl, having not less than 4 carbon atoms, or aryl or aryloxy, and a compound having the formula [II]or [III]: wherein R 4 and R 5 are each alkyl, aryl or aralkyl having not less than 5 carbon atoms; wherein R 6 , R 7 and R 8 are each alkyl having not less than 5 carbon atoms or aryl.
Claim 3
Dependent Claim 81 words
A color photographic light-sensitive material according to Claim 1, characterized in that R 1 and R 2 independently are alkyl, alkoxy, or alkenyl, each having 4 to 8 carbon atoms, or substituted or unsubstituted phenyl or phenoxy; R 4 and R 5 independently are alkyl having 5 to 16 carbon atoms, or substituted or unsubstituted phenyl or benzyl; and R 6 , R 7 and R 8 independently are alkyl having 5 to 16 carbon atoms or substituted or unsubstituted phenyl.
Claim 4
Dependent Claim 66 words
A color photographic light-sensitive material according to Claim 1 or 2, characterized in that said benzotriazole derivative is incorporated in said nonlight-sensitive layer in an amount from 0.001 to 2 parts by weight, based on binder in said nonlight-sensitive layer, and the compound of II and/or III is incorporated in an amount of 0.01 to 5 parts by weight per part by weight of benzotriazole derivative.
Claim 5
Dependent Claim 39 words
A color photographic material according to any of Claims 1 to 3 characterized by having at least two silver halide emulsion layers each of which layers being sensitive to a different spectral region and containing a different dye-forming coupler.
Claim 6
Dependent Claim 25 words
A color photographic material according to any preceding Claim characterized in that said nonlight-sensitive layer is provided with another nonlight-sensitive layer comprising a hydrophilic colloid.
