Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
44 words
A transparency-making recording sheet comprising: a transparent substrate; a support sheet releasably provided on a non-recording surface of the transparent substrate; and a thermoplastic resin layer interposed between the transparent substrate and the support sheet, the thermoplastic resin being formed by an extrusion coating.
Claim 2
Dependent Claim
44 words
A transparency-making recording sheet comprising: a transparent substrate; a support sheet releasably provided on a non-recording surface of the transparent substrate; and a thermoplastic resin layer interposed between the transparent substrate and the support sheet, the thermoplastic resin being formed by an extrusion coating.
Claim 3
Dependent Claim
17 words
The transparency-making recording sheet according to claim 1, wherein said thermoplastic resin layer comprises a polyolefin resin.
Claim 4
Dependent Claim
23 words
The transparency-making recording sheet according to claim 2, wherein either one of said transparent substrate and support sheet is provided with a half-cut.
Claim 5
Dependent Claim
19 words
The transparency-making recording sheet according to claim 1, wherein said transparent substrate is releasable from said thermoplastic resin layer.
Claim 6
Dependent Claim
23 words
The transparency-making recording sheet according to claim 4, wherein either one of said transparent substrate and support sheet is provided with a half-cut.
Claim 7
Dependent Claim
23 words
The transparency-making recording sheet according to claim 1, wherein either one of said transparent substrate and support sheet is provided with a half-cut.
Claim 8
Dependent Claim
18 words
The transparency-making recording sheet according to claim 1, wherein the recording sheet is used for sublimation transfer recording.
Claim 9
Dependent Claim
25 words
The transparency-making recording sheet according to claim 7, further comprising a receiving layer comprising a dyeable resin, the receiving layer formed on the transparent substrate.
Claim 10
Dependent Claim
17 words
The transparency-making recording sheet according to claim 1, wherein said thermoplastic resin layer is a release layer.
Claim 11
Dependent Claim
20 words
The transparency-making recording sheet according to claim 1, wherein said support sheet is releasable directly from said thermoplastic resin layer.
Claim 12
Dependent Claim
19 words
