Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
60 words
A carrier for transferring images to an image receiver comprising a paper treated with a release agent selected from the group consisting of silicones, polyethylene, and polytetrafluoroethylene, and a transparent binder suspension layer disposed thereon, said binder suspension consisting essentially of a solid suspension in a solvent, said solid comprising a nitrile butadiene rubber obtained by copolymerizing butadiene with acrylonitrile.
Claim 2
Dependent Claim
60 words
A carrier for transferring images to an image receiver comprising a paper treated with a release agent selected from the group consisting of silicones, polyethylene, and polytetrafluoroethylene, and a transparent binder suspension layer disposed thereon, said binder suspension consisting essentially of a solid suspension in a solvent, said solid comprising a nitrile butadiene rubber obtained by copolymerizing butadiene with acrylonitrile.
Claim 3
Dependent Claim
24 words
Image carrier according to claim 1, wherein the binder emulsion has a solid content of 25 to 40 %, the rest being ketone solvents.
Claim 4
Dependent Claim
28 words
Image carrier according to claim 1, characterized in that said nitrile butadiene rubber is obtained by copolymerization of 25 to 35 % of acrylonitrile, the rest being butadiene.
Claim 5
Dependent Claim
75 words
A carrier for transferring images to an image receiver comprising a paper treated with a release agent selected from the group consisting of silicones, polyethylene, and polytetrafluoroethylene, and a binder suspension layer disposed thereon, said binder suspension consisting essentially of a solid suspended in a solvent, said solid comprising a nitrile butadiene rubber obtained by copolymerizing butadiene with acrylonitrile, said carrier further comprising a thin layer of photosensitive photographic emulsion overlying the binder suspension layer.
Claim 6
Dependent Claim
75 words
A carrier for transferring images to an image receiver comprising a paper treated with a release agent selected from the group consisting of silicones, polyethylene, and polytetrafluoroethylene, and a binder suspension layer disposed thereon, said binder suspension consisting essentially of a solid suspended in a solvent, said solid comprising a nitrile butadiene rubber obtained by copolymerizing butadiene with acrylonitrile, said carrier further comprising a thin layer of photosensitive photographic emulsion overlying the binder suspension layer.
