Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
45 words
A silver halide photographic light-sensitive material containing at least one photographic layer containing silver halide and an uppermost layer containing as a binder acid-processed gelatin and polymethylmethacrylate as a matting agent which is powdered and which has average particle sizes of about 0.2 to 10μ.
Claim 2
Dependent Claim
45 words
A silver halide photographic light-sensitive material containing at least one photographic layer containing silver halide and an uppermost layer containing as a binder acid-processed gelatin and polymethylmethacrylate as a matting agent which is powdered and which has average particle sizes of about 0.2 to 10μ.
Claim 3
Dependent Claim
35 words
The photographic light-sensitive material of claim 1, wherein said acid-processed gelatin is present in said uppermost layer in an amount greater than about 20% of the total weight of the binders of said uppermost layer.
Claim 4
Dependent Claim
22 words
The photographic light-sensitive material of claim 1, wherein said acid-processed gelatin has an isoelectric point of a pH of 6.0 to 9.5.
Claim 5
Dependent Claim
55 words
The photographic light-sensitive material of claim 1, wherein said uppermost layer contains one or more additional binders selected from the group consisting of natural high molecular weight materials, chemically modified natural high molecular weight materials other than acid-processed gelatin, and synthetic high molecular weight materials prepared by polymerizing a monomer having an ethylenic double bond.
Claim 6
Dependent Claim
34 words
The photographic light-sensitive material of claim 1, wherein said matting agent is present in said uppermost layer in an amount of about 1 to 100 mg/g of the binder present in said uppermost layer.
Claim 7
Dependent Claim
15 words
The photographic light-sensitive material of claim 1, wherein said uppermost layer contains a gelatin derivative.
Claim 8
Dependent Claim
29 words
The photographic light-sensitive material of claim 1, wherein said uppermost layer contains a synthetic high molecular weight material containing a carboxyl group or a salt of a carboxyl group.
Claim 9
Dependent Claim
19 words
The photographic light-sensitive material of claim 1, wherein said uppermost layer contains a hardening agent for said acid-processed gelatin.
Claim 10
Dependent Claim
47 words
The photographic light-sensitive material of claim 1, in which the support has thereon a blue-sensitive silver halide emulsion layer containing a yellow forming coupler, a green-sensitive silver halide emulsion layer containing a magenta forming coupler and a red-sensitive silver halide emulsion layer containing a cyan forming coupler.
Claim 11
Independent Claim
57 words
A method for minimizing reticulation in a photographic light-sensitive material containing silver halide on processing said light-sensitive material at a temperature above 30° C. comprising incorporating in said light-sensitive material an uppermost photographic layer containing acid-processed gelatin and polymethylmethacrylate as a matting agent which is powdered and which has average particle size of about 0.2 to 10μ.
Claim 12
Independent Claim
57 words
A method for minimizing reticulation in a photographic light-sensitive material containing silver halide on processing said light-sensitive material at a temperature above 30° C. comprising incorporating in said light-sensitive material an uppermost photographic layer containing acid-processed gelatin and polymethylmethacrylate as a matting agent which is powdered and which has average particle size of about 0.2 to 10μ.
