Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
43 words
A thermal mass transfer donor element comprising a substrate having coated thereon a thermally mass transferrable, clear, dye-receptive binder layer, wherein said binder layer comprises 5-30% by weight of particulates, 50-90% by weight of waxy material, and 3-28% by weight of thermoplastic polymers.
Claim 2
Dependent Claim
43 words
A thermal mass transfer donor element comprising a substrate having coated thereon a thermally mass transferrable, clear, dye-receptive binder layer, wherein said binder layer comprises 5-30% by weight of particulates, 50-90% by weight of waxy material, and 3-28% by weight of thermoplastic polymers.
Claim 3
Dependent Claim
34 words
The donor element of claim 1 wherein said dye receptive binder layer has an optical density to visible light between 400 and 700 nm of less than 0.2 at a thickness of 10 micrometers.
Claim 4
Dependent Claim
29 words
The element of claim 2 wherein said dye receptive binder is capable of absorbing at least one sublimable dye selected from the group of anthraquinone, azo, and sulfone dyes.
Claim 5
Dependent Claim
27 words
The donor element of claim 1 wherein, in addition to areas of said binder layer, there is at least one separate area of thermal dye transferable material.
Claim 6
Dependent Claim
29 words
The element of claim 4, wherein said dye receptive binder is capable of absorbing at least one sublimable dye selected from the group of anthraquinone, azo, and sulfone dyes.
Claim 7
Dependent Claim
12 words
The element of claim 4 wherein said thermoplastic polymer comprises polyvinyl acetate.
Claim 8
Dependent Claim
29 words
The element of claim 1 wherein said dye receptive binder is capable of absorbing at least one sublimable dye selected from the group of anthraquinone, azo, and sulfone dyes.
Claim 9
Dependent Claim
12 words
The element of claim 1 wherein said thermoplastic polymer comprises polyvinyl acetate.
Claim 10
Dependent Claim
35 words
The element of claim 1 wherein the particulates have a coefficient of thermal expansion which differs from the coefficient of thermal expansion for the polymers and the wax by at least a factor of 10.
Claim 11
Dependent Claim
71 words
A process for providing a mixed thermal mass transfer and thermal dye transfer image comprising thermal mass transferring a transparent or translucent dye-receptive image onto a receptor surface and thermal dye transferring a dye on top of at least part of said dye-receptive image, wherein said transparent or translucent dye receptive image comprises 5-30% by weight of particulates, 50-90% by weight of waxy material, and 3-28% by weight of thermoplastic polymers.
Claim 12
Dependent Claim
71 words
A process for providing a mixed thermal mass transfer and thermal dye transfer image comprising thermal mass transferring a transparent or translucent dye-receptive image onto a receptor surface and thermal dye transferring a dye on top of at least part of said dye-receptive image, wherein said transparent or translucent dye receptive image comprises 5-30% by weight of particulates, 50-90% by weight of waxy material, and 3-28% by weight of thermoplastic polymers.
Claim 13
Dependent Claim
29 words
The process of claim 10 wherein a transparent image is thermally mass transferred and said dye image is subsequently transferred onto at least a part of said transparent image.
Claim 14
Dependent Claim
28 words
The process of claim 10 wherein said transferring of said transparent or translucent image and said dye image are performed off the same ribbon or sheet in sequence.
Claim 15
Dependent Claim
29 words
The process of claim 10 wherein said dye receptive binder is capable of absorbing at least one sublimable dye selected from the group of anthraquinone, azo, and sulfone dyes.
Claim 16
Dependent Claim
31 words
The process of claim 10 wherein said receptor serves only as an intermediate medium and said transparent or translucent image and said dye image are simultaneously transferred to a final receptor.
Claim 17
Dependent Claim
14 words
The process of claim 14 wherein the said intermediate medium is a polymeric film.
Claim 18
Dependent Claim
35 words
The process of claim 10 wherein the particulates have a coefficient of thermal expansion which differs from the coefficient of thermal expansion for the polymers and the wax by at least a factor of 10.
