Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
45 words
A silver halide photographic material that has at least one hydrophilic colloidal layer on a support, wherein said at least one hydrophilic colloidal layer contains an organic fluoro-compound and/or a nonionic surfactant having a polyoxyethylene unit and is hardened with a high-molecular weight hardening agent.
Claim 2
Dependent Claim
45 words
A silver halide photographic material that has at least one hydrophilic colloidal layer on a support, wherein said at least one hydrophilic colloidal layer contains an organic fluoro-compound and/or a nonionic surfactant having a polyoxyethylene unit and is hardened with a high-molecular weight hardening agent.
Claim 3
Dependent Claim
47 words
A silver halide photographic material according to Claim 1 wherein said hydrophilic colloidal layer that contains an organic fluoro-compound and/or nonionic surfactant having a polyoxyethylene unit and which is hardened with a high-molecular weight hardening agent is a non-light-sensitive layer that is situated farthest from the support.
Claim 4
Dependent Claim
30 words
A silver halide photographic material according to Claim 1 wherein said at least one hydrophilic colloidal layer contains an organic fluoro-compound and is hardened with a high-molecular weight hardening agent.
Claim 5
Dependent Claim
56 words
A silver halide photographic material according to Claim 3 wherein said organic fluoro-compound is a fluorine-containing surfactant of the following formula: where Rf is an alkyl, alkenyl or aryl group having at least three fluorine atoms; A is a divalent linking group; X is a hydrophilic group; and m is an integer of 0 or 1.
Claim 6
Dependent Claim
43 words
A silver halide photographic material according to Claim 1 wherein said hydrophilic colloidal layer is hardened with a high-molecular weight hardening agent that has as a hardening group either a vinyl sulfone group or a group from which a vinyl sulfone is derived.
Claim 7
Dependent Claim
15 words
A silver halide photographic material according to Claim 1 which is a color photographic material.
Claim 8
Dependent Claim
33 words
A silver halide photographic material according to Claim 1 wherein the non-light-sensitive layer that is situated farthest from the support contains an organic fluoro-compound and is hardened with a high-molecular weight hardening agent.
Claim 9
Dependent Claim
56 words
A silver halide photographic material according to Claim 7 wherein said organic fluoro-compound is a fluorine-containing surfactant of the following formula: where Rf is an alkyl, alkenyl or aryl group having at least three fluorine atoms; A is a divalent linking group; X is a hydrophilic group; and m is an integer of 0 or 1.
Claim 10
Dependent Claim
31 words
A silver halide photographic material according to Claim 7 wherein said high-molecular weight hardening agent has a vinyl sulfone group or a group from which a vinyl sulfone group is derived.
Claim 11
Dependent Claim
48 words
A silver halide photographic material according to Claim 6 wherein said hydrophilic colloidal layer that contains an organic fluoro-compound and/or a nonionic surfactant having a polyoxyethylene unit and which is hardened with a high-molecular weight hardening agent is the non-light-sensitive layer that is situated farthest from the support.
Claim 12
Dependent Claim
90 words
A silver halide photographic material according to Claim 3 wherein at least one hydrophilic colloidal layer contains a fluorine-containing surfactant of the following formula and is hardened with a high-molecular weight hardening agent that contains as a hardening group either a vinyl sulfone group or a group from which a vinyl sulfone group is derived: where Rf is an alkyl, alkenyl or aryl group having at least three fluorine atoms; A is a divalent linking group; X is a hydrophilic group; and m is an integer of 0 or 1.
Claim 13
Dependent Claim
62 words
A silver halide photographic material according to Claim 6 wherein the non-light-sensitive layer that is situated farthest from the support contains an organic fluoro-compound and/or a nonionic surfactant having a polyoxyethylene unit and is hardened with a high-molecular weight hardening agent that contains in its molecule either a vinyl sulfone group or a group from which a vinyl sulfone group is derived.
Claim 14
Dependent Claim
55 words
A silver halide photographic material according to Claim 6 wherein the non-light sensitive layer that is situated farthest from the support contains an organic fluoro-compound and is hardened with a high-molecular weight hardening agent that contains in its molecule either a vinyl sulfone group or a group from which a vinyl sulfone group is derived.
