Abstract

Abstract A silver halide color photographic light-sensitive material have at least one hydrophilic colloid layer containing a compound represented by Formula (A) below on a support consisting of a belt-like polyester base: Formula (A)   A-(Time) n -W wherein A represents a group capable of releasing (Time) n -W upon reacting with an oxidized form of a color developing agent, Time represents a timing group, W represents a group which exhibits a development inhibiting effect after released from (Time) n -W, and n represents 1, 2, or 3. Four or less perforations are formed per frame in one or both of side edge portions of the polyester base, the area of an imaging area is 3.0 cm² to 7.0 cm², and the aspect ratio of the imaging area is 1.40 to 2.50. This light-sensitive material can form a color image excellent in image qualities, particularly sharpness and color reproducibility and can thereby decrease the thickness of a support, making miniaturization of a cartridge possible without impairing image qualities.

Claims Analysis

Total Claims: 10
Claim 1
Independent Claim 135 words
A silver halide color photographic light-sensitive material having at least one hydrophilic colloid layer containing a compound represented by Formula (A) below on a support, characterized in that said support comprises a belt-like polyester base, not more than four perforations are formed per frame in one or both of side edge portions of said polyester base, the area of an imaging area is 3.0 cm² to 7.0 cm², and the aspect ratio of the imaging area is 1.40 to 2.50: Formula (A)   A-(Time) n -W wherein A represents a group capable of releasing (Time) n -W upon reacting with an oxidized form of a color developing agent, Time represents a timing group, W represents a group which exhibits a development inhibiting effect after released from (Time) n -W, and n represents 1, 2, or 3.
Claim 2
Dependent Claim 29 words
A material according to claim 1, characterized in that said support is heat-treated at a temperature lower by 30°C to 50°C than the glass transition temperature of said support.
Claim 3
Dependent Claim 20 words
A material according to claim 1, characterized in that a thickness of said support is 40 µm to 300 µm.
Claim 4
Dependent Claim 13 words
A material according to claim 1, characterized in that said support contains dyes.
Claim 5
Dependent Claim 53 words
A material according to claim 1, characterized in that said material has a back layer which contains a fine grain of at least one crystalline metal oxide selected from the group consisting of ZnO, TiO₃, SnO₂, Aℓ₂O₃, In₂O₃, SiO₂, MgO, BaO, and MoO₃, or fine grain of a composite oxide of these oxides.
Claim 6
Dependent Claim 30 words
A material according to claim 1, characterized in that a ratio of the total area of said perforations is 5% or less with respect to the area of one frame.
Claim 7
Dependent Claim 48 words
A material according to claim 1, characterized in that said compound represented by Formula (A) is contained in a light-sensitive silver halide emulsion layer, and an addition amount of said compound is 0.01 to 20 mol% with respect to an amount of a silver halide in that layer.
Claim 8
Dependent Claim 53 words
A material according to claim 1, characterized in that said compound represented by Formula (A) is contained in a non-light-sensitive layer, and an addition amount of said compound is 0.01 to 20 mol% with respect to an amount of a silver halide in a silver halide emulsion layer closet to said non-light-sensitive layer.
Claim 9
Dependent Claim 15 words
A material according to claim 1, characterized in that said support is made from polyethylene-2,6-dinaphthalate.
Claim 10
Dependent Claim 28 words
A material according to claim 9, characterized in that said support is heat-treated at a temperature lower by 30°C to 50°C than the glass transition temperature of polyethylene-2,6-dinaphthalate.
