Abstract
Abstract A silver halide photographic sensitive material is described comprising a compound represented by formula (I) ##STR1## wherein Rf represents a saturated or unsaturated hydrocarbon group having from 3 to 20 carbon atoms wherein all or a part of the hydrogen atoms are substituted by fluorine atoms, each of L 1 and L 2 represents a divalent linking group, each of R 1 , R 2 , and R 3 represents a hydrogen atom, a methyl group, or an ethyl group, each of R 4 , R 5 , and R 6 represents an alkyl group having from 1 to 6 carbon atoms, X represents an anion, and each of a and b represents 0, 1, or 2.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
158 words
A light sensitive photographic element having at least a support and a silver halide emulsion layer wherein at least one layer of the element contains an antistatic compound represented by formula (I) ##STR16## wherein Rf represents a saturated or unsaturated hydrocarbon group having from 3 to 20 carbon atoms wherein all or a part of the hydrogen atoms are substituted by fluorine atoms, each of L 1 and L 2 represents a divalent linking group, each of R 1 , R 2 , and R 3 represents a hydrogen atom, a methyl group, or an ethyl group, each of R 4 , R 5 , and R 6 represents an alkyl group having from 1 to 6 carbon atoms, X represents an anion, and each of a and b represents 0, 1, or 2, and wherein the concentration of the compound represented by formula (I) is at least 0.0001 grams per square meter of the photographic sensitive material.
Claim 2
Dependent Claim
158 words
A light sensitive photographic element having at least a support and a silver halide emulsion layer wherein at least one layer of the element contains an antistatic compound represented by formula (I) ##STR16## wherein Rf represents a saturated or unsaturated hydrocarbon group having from 3 to 20 carbon atoms wherein all or a part of the hydrogen atoms are substituted by fluorine atoms, each of L 1 and L 2 represents a divalent linking group, each of R 1 , R 2 , and R 3 represents a hydrogen atom, a methyl group, or an ethyl group, each of R 4 , R 5 , and R 6 represents an alkyl group having from 1 to 6 carbon atoms, X represents an anion, and each of a and b represents 0, 1, or 2, and wherein the concentration of the compound represented by formula (I) is at least 0.0001 grams per square meter of the photographic sensitive material.
Claim 3
Dependent Claim
29 words
A silver halide photographic sensitive element as in claim 1, wherein the compound represented by formula (I) is present in a layer other than a silver halide emulsion layer.
Claim 4
Dependent Claim
40 words
A silver halide photographic sensitive element as in claim 1, wherein the compound represented by formula (I) is present in at least one layer selected from a surface protective layer, a back layer, an intermediate layer, and a subbing layer.
Claim 5
Dependent Claim
32 words
A silver halide photographic sensitive element as in claim 1, wherein the compound represented by formula (I) is present in at least one of a surface protective layer and a back layer.
Claim 6
Dependent Claim
35 words
A silver halide photographic sensitive element as in claim 1, 2, 3, or 4, wherein the concentration of compound represented by formula (I) is from 0.0001 to 2.0 g/m 2 of the photographic sensitive material.
Claim 7
Dependent Claim
35 words
A silver halide photographic sensitive element as in claim 1, 2, 3, or 4, wherein the concentration of compound represented by formula (I) is from 0.0005 to 0.05 g/m 2 of the photographic sensitive material.
