Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
28 words
A protective layer transfer film comprising: a substrate film, and a thermally-transferable resin layer provided thereon, which comprises a resin combined with a reactive ultraviolet-absorbing agent by reaction.
Claim 2
Dependent Claim
28 words
A protective layer transfer film comprising: a substrate film, and a thermally-transferable resin layer provided thereon, which comprises a resin combined with a reactive ultraviolet-absorbing agent by reaction.
Claim 3
Dependent Claim
89 words
The protective layer transfer film according to claim 1, wherein the resin combined with a reactive ultraviolet-absorbing agent by reaction is a copolymer of a reactive ultraviolet-absorbing agent represented by the formula (I): ##STR12## wherein R is H or CH 3 , and X is --CH 2 CH 2 -- or ##STR13## or by the formula (II): ##STR14## wherein R is H or CH 3 , and X is --CH 2 CH 2 -- or ##STR15## and at least one of thermoplastic resin monomers and oligomers, and reactive polymers.
Claim 4
Dependent Claim
31 words
The protective layer transfer film according to claim 2, wherein the copolymer is a copolymer of the reactive ultraviolet-absorbing agent and at least one of acrylic monomers, oligomers and reactive polymers.
Claim 5
Dependent Claim
58 words
The protective layer transfer film according to claim 1, wherein the thermally-transferable resin layer comprises a laminate composed of a transparent resin layer and a thermally-adhesive resin layer which are laminated on the substrate film in the mentioned order, and at least one of these resin layers comprises the resin combined with a reactive ultraviolet-absorbing agent by reaction.
Claim 6
Dependent Claim
66 words
The protective layer transfer film according to claim 1, wherein the thermally-transferable resin layer comprises a laminate composed of a transparent resin layer and a thermally-adhesive resin layer which are laminated on the substrate film in the mentioned order, and an ultraviolet-screening layer comprising the resin combined with a reactive ultraviolet-absorbing agent by reaction is provided between the transparent resin layer and the thermally-adhesive resin layer.
Claim 7
Dependent Claim
35 words
The protective layer transfer film according to claim 1, wherein a sublimable dye layer and/or a thermal fusing ink layer are(is) formed on the substrate film side by side together with the thermally-transferable resin layer.
Claim 8
Dependent Claim
47 words
Image-printed matter comprising: an image-receiving material containing at least an image colored with a dye on the surface thereof, and the thermally-transferable resin layer of the protective layer transfer film of claim 1 laminated on at least a part of the image-printed surface of the image-receiving material.
