Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
86 words
A silver halide photographic light-sensitive material comprising: (a) a polyester support; (b) a silver halide emulsion layer coated on one side of said polyester support; (c) a resin layer coated on the other side of said polyester support, said resin layer comprising an antistatic agent selected from the group consisting of a conductive polymer and a metal oxide, and a resin selected from the group consisting of an aqueous-dispersible polyester resin and an aqueous-dispersible polyurethane resin; and (d) a magnetic layer coated on said resin layer.
Claim 2
Dependent Claim
86 words
A silver halide photographic light-sensitive material comprising: (a) a polyester support; (b) a silver halide emulsion layer coated on one side of said polyester support; (c) a resin layer coated on the other side of said polyester support, said resin layer comprising an antistatic agent selected from the group consisting of a conductive polymer and a metal oxide, and a resin selected from the group consisting of an aqueous-dispersible polyester resin and an aqueous-dispersible polyurethane resin; and (d) a magnetic layer coated on said resin layer.
