Claims Analysis
Total Claims: 21
Claim 1
Independent Claim
56 words
A thermal transfer ribbon comprising: a substrate constituted of a synthetic-resin foil band; a fusible synthetic-resin-bonded color-transfer layer on a surface of said foil and responsive to heat for transfer of an image upon heating; and a further layer on a surface of said fusible synthetic-resin-bonded color-transfer layer facing away from said substrate consisting of wax.
Claim 2
Dependent Claim
56 words
A thermal transfer ribbon comprising: a substrate constituted of a synthetic-resin foil band; a fusible synthetic-resin-bonded color-transfer layer on a surface of said foil and responsive to heat for transfer of an image upon heating; and a further layer on a surface of said fusible synthetic-resin-bonded color-transfer layer facing away from said substrate consisting of wax.
Claim 3
Dependent Claim
21 words
The thermal transfer ribbon defined in claim 1 wherein said wax layer has a thickness of substantially 0.5 to 3 micrometer.
Claim 4
Dependent Claim
33 words
The thermal transfer ribbon defined in claim 1 wherein said wax layer is composed of a wax selected from the group which consists of natural waxes, paraffin waxes, silicone waxes, and synthetic waxes.
Claim 5
Dependent Claim
27 words
The thermal transfer ribbon defined in claim 3 wherein said wax is a natural wax selected from the group which consists of carnauba wax, beeswax and ozocerite.
Claim 6
Dependent Claim
36 words
The thermal transfer ribbon defined in claim 3 wherein said wax is a synthetic wax selected from the group which consists of acid waxes, unsasponified ester waxes, partially saponified ester waxes, polyethylene waxes, and mixtures thereof.
Claim 7
Dependent Claim
29 words
The thermal transfer ribbon defined in claim 1 wherein said fusible synthetic-resin-bonded color-transfer layer contains a thermoplastic binder with a softening point of about 70° to about 120° C.
Claim 8
Dependent Claim
28 words
The thermal transfer ribbon defined in claim 1 wherein said synthetic-resin foil band is composed of a thermoplastic material having a softening point in excess of 190° C.
Claim 9
Dependent Claim
16 words
The thermal transfer ribbon defined in claim 7 wherein said thermoplastic material is a polyester film.
Claim 10
Dependent Claim
41 words
The thermal transfer ribbon defined in claim 1 wherein said fusible synthetic-resin-bonded color-transfer layer contains a thermoplastic binder selected from the group which consists of a polystyrene, a polyamide, a polyvinylacetate, an ethylene-vinylacetate copolymer, a polymethacrylate, a polyacrylate and mixtures thereof.
Claim 11
Independent Claim
123 words
A method of making a thermal transfer ribbon comprising: a substrate constituted of a synthetic-resin foil band: a fusible synthetic-resin-bonded color-transfer layer on a surface of said foil and responsive to heat for transfer of an image upon heating; and a further layer on a surface of said fusible synthetic-resin-bonded color-transfer layer facing away from said substrate consisting of wax, said method comprising the steps of: coating said fusible synthetic-resin-bonded color-transfer layer onto said band in the form of an aqueous suspension and evaporating water from said suspension to form said synthetic-resin-bonded color-transfer layer thereon; and coating said further layer of wax onto said fusible synthetic-resin-bonded color-transfer layer in the form of an aqueous suspension and evaporating water from the latter aqueous suspension.
Claim 12
Independent Claim
123 words
A method of making a thermal transfer ribbon comprising: a substrate constituted of a synthetic-resin foil band: a fusible synthetic-resin-bonded color-transfer layer on a surface of said foil and responsive to heat for transfer of an image upon heating; and a further layer on a surface of said fusible synthetic-resin-bonded color-transfer layer facing away from said substrate consisting of wax, said method comprising the steps of: coating said fusible synthetic-resin-bonded color-transfer layer onto said band in the form of an aqueous suspension and evaporating water from said suspension to form said synthetic-resin-bonded color-transfer layer thereon; and coating said further layer of wax onto said fusible synthetic-resin-bonded color-transfer layer in the form of an aqueous suspension and evaporating water from the latter aqueous suspension.
Claim 13
Dependent Claim
19 words
The method defined in claim 10 wherein said wax layer has a thickness of substantially 0.5 to 3 micrometer.
Claim 14
Dependent Claim
33 words

The method defined in claim 12 wherein said wax is a synthetic wax selected from the group which consists of acid waxes, unsaponified ester waxes, partially saponified ester waxes, polyethylene waxes, and mixtures thereof.
Claim 17
Dependent Claim
27 words
The method defined in claim 12 wherein said fusible synthetic-resin-bonded color-transfer layer contains a thermoplastic binder with a softening point of about 70° to about 120° C.
Claim 18
Dependent Claim
26 words
The method defined in claim 15 wherein said synthetic-resin foil band is composed of a thermoplastic material having a softening point in excess of 190° C.
Claim 19
Dependent Claim
14 words
The method defined in claim 16 wherein said thermoplastic material is a polyester film.
Claim 20
Dependent Claim
39 words
The method defined in claim 17 wherein said fusible synthetic-resin-bonded color-transfer layer contains a thermoplastic binder selected from the group which consists of a polystyrene, a polyamide, a polyvinylacetate, an ethylene-vinylacetate copolymer, a polymethacrylate, a polyacrylate and mixtures thereof.
