Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
83 words
A label for heat transfer labeling comprising a carrier; an imprinted, discontinuous, thermoplastic and resinous release layer on said carrier, said layer containing a repellent thermoplastic silicone material therein; and a transfer layer, including a design superimposed upon continuous portions of said release layer which is discontinuous elsewhere; said release layer having continuous portions, each with a border in conformity with the design of the transfer layer superimposed thereon; said release layer being carried with said transfer layer during the heat transfer step.
Claim 2
Dependent Claim
83 words
A label for heat transfer labeling comprising a carrier; an imprinted, discontinuous, thermoplastic and resinous release layer on said carrier, said layer containing a repellent thermoplastic silicone material therein; and a transfer layer, including a design superimposed upon continuous portions of said release layer which is discontinuous elsewhere; said release layer having continuous portions, each with a border in conformity with the design of the transfer layer superimposed thereon; said release layer being carried with said transfer layer during the heat transfer step.
Claim 3
Dependent Claim
84 words
A label for heat transfer labeling comprising a carrier; an imprinted, discontinuous, thermoplastic and resinous release layer on said carrier; and a transfer layer, including a design pattern superimposed upon a continuous portion of said release layer, which is discontinuous elsewhere; the continuous portion of said release layer underlying each design pattern having a closed border which is substantially the same as an exterior closed border of the design pattern; said release layer being carried with said transfer layer during the heat transfer step.
Claim 4
Dependent Claim
84 words
A label for heat transfer labeling comprising a carrier; an imprinted, discontinuous, thermoplastic and resinous release layer on said carrier; and a transfer layer, including a design pattern superimposed upon a continuous portion of said release layer, which is discontinuous elsewhere; the continuous portion of said release layer underlying each design pattern having a closed border which is substantially the same as an exterior closed border of the design pattern; said release layer being carried with said transfer layer during the heat transfer step.
Claim 5
Dependent Claim
83 words
A label for heat transfer labeling comprising a carrier; an imprinted, discontinuous, thermoplastic and resinous release layer on said carrier; and a transfer layer, including a design pattern superimposed upon a continuous portion of said release layer, which is discontinuous elswehere; the continuous portion of said release layer underlying said design pattern having a closed border which is substantially parallel with an exterior closed border of the design pattern; said release layer being carried with said transfer layer during the heat transfer step.
Claim 6
Dependent Claim
83 words
A label for heat transfer labeling comprising a carrier; an imprinted, discontinuous, thermoplastic and resinous release layer on said carrier; and a transfer layer, including a design pattern superimposed upon a continuous portion of said release layer, which is discontinuous elswehere; the continuous portion of said release layer underlying said design pattern having a closed border which is substantially parallel with an exterior closed border of the design pattern; said release layer being carried with said transfer layer during the heat transfer step.
Claim 7
Dependent Claim
30 words
A label as defined in any of claims 1-3 wherein the release layer and the transfer layer are approximately co-terminus and have an outline differing from that of the carrier.
Claim 8
Dependent Claim
25 words
A label as defined in any of claims 1-3 wherein said release layer has a margin with respect to the contour of said transfer layer.
Claim 9
Dependent Claim
25 words
A label as defined in any of claims 1-3 wherein said transfer layer has a margin with respect to the contour of said release layer.
Claim 10
Dependent Claim
26 words
A label as defined in claim 1 wherein said release layer has a melt viscosity in the range from 3.5 to 8.5 poises at 160° C.
Claim 11
Dependent Claim
23 words
A label as defined in claim 1 wherein said release layer has a softening point in the range from 95° to 106° C.
Claim 12
Dependent Claim
38 words
A label as defined in claim 1 wherein said release layer is a polyamide or a polystyrene resin or a rosin derivative or phenol formaldehyde resin or a terpene resin or a ketone resin or a mixture thereof.
Claim 13
Dependent Claim
50 words
A method of manufacturing a heat transfer label as defined in claim 1 which comprises the steps of (a) dissolving the material of the release layer in a solvent to form a solution; (b) printing said solution onto a carrier; and (c) printing the transfer layer onto the release layer.
Claim 14
Dependent Claim
62 words
A method of labeling an object with a label as defined in claim 1 which comprises the steps of (a) applying said label to said object; (b) heating said label to cause the release layer to soften and be removable from said carrier; and (c) transferring said transfer layer to said object with said release layer superimposed thereon and approximately co-terminus therewith.
