Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
48 words
A photographic light-sensitive material containing an uppermost layer consisting essentially of acid-processed gelatin and a surface active organic fluoro-compound, wherein said organic fluoro-compound contains in the molecule thereof at least three fluorine atoms and a group in which at least three carbon atoms combine to form carbon-carbon bonds.
Claim 2
Dependent Claim
48 words
A photographic light-sensitive material containing an uppermost layer consisting essentially of acid-processed gelatin and a surface active organic fluoro-compound, wherein said organic fluoro-compound contains in the molecule thereof at least three fluorine atoms and a group in which at least three carbon atoms combine to form carbon-carbon bonds.
Claim 3
Dependent Claim
30 words
The photographic light-sensitive material as claimed in claim 1, wherein the amount of the organic fluoro-compound is about 0.1 to 10 g/100 g of the binder in the uppermost layer.
Claim 4
Dependent Claim
17 words
The photographic light-sensitive material as claimed in claim 1, wherein said uppermost layer contains a matting agent.
Claim 5
Dependent Claim
25 words
The photographic light-sensitive material as claimed in claim 1 comprising a support having thereon at least one silver halide emulsion layer and said uppermost layer.
Claim 6
Dependent Claim
48 words
The photographic light-sensitive material as claimed in claim 4, wherein said support has thereon a blue-sensitive silver halide emulsion layer containing a yellow color-forming coupler, a green-sensitive silver halide emulsion layer containing a magenta color-forming coupler and a red-sensitive silver halide emulsion layer containing a cyan color-forming coupler.
Claim 7
Dependent Claim
34 words
The photographic light-sensitive material as claimed in claim 1, wherein said organic fluoro-compound contains a chain structure or a cyclic structure and contains at least three fluorine atoms and at least three carbon atoms.
Claim 8
Dependent Claim
17 words
The photographic light-sensitive material as claimed in claim 1, wherein said uppermost layer contains a lubricating agent.
Claim 9
Dependent Claim
18 words
The photographic light-sensitive material as claimed in claim 1, wherein said uppermost layer contains another surface active agent.
Claim 10
Dependent Claim
22 words
The photographic light-sensitive material as claimed in claim 1, wherein said uppermost layer contains a hardening agent for the acid processed gelatin.
