Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
91 words
A thermal transfer printing receiver sheet for use in association with a compatible donor sheet, the receiver sheet comprising a supporting substrate having, on at least one surface thereof, a dye-receptive receiving layer to receive a dye thermally transferred from the donor sheet, characterized in that the receiving layer comprises a dye-receptive polymer and from 0.5% to 30% by weight of the layer of at least one antiplasticiser therefor wherein said antiplasticiser comprises at least one aromatic ester of molecular weight not exceeding 1,000 and said dye-receptive polymer comprises a polyester.
Claim 2
Dependent Claim
91 words
A thermal transfer printing receiver sheet for use in association with a compatible donor sheet, the receiver sheet comprising a supporting substrate having, on at least one surface thereof, a dye-receptive receiving layer to receive a dye thermally transferred from the donor sheet, characterized in that the receiving layer comprises a dye-receptive polymer and from 0.5% to 30% by weight of the layer of at least one antiplasticiser therefor wherein said antiplasticiser comprises at least one aromatic ester of molecular weight not exceeding 1,000 and said dye-receptive polymer comprises a polyester.
Claim 3
Dependent Claim
19 words
A receiver sheet according to claim 1 wherein the aromatic ester comprises a single independent benzene or naphthalene ring.
Claim 4
Dependent Claim
17 words
A receiver sheet according to claim 2 wherein the aromatic ester comprises at least one halogen atom.
Claim 5
Dependent Claim
15 words
A receiver sheet according to claim 3 wherein the halogen atom is a chlorine atom.
Claim 6
Dependent Claim
14 words
A receiver sheet according to claim 1 wherein the dye-receptive polymer comprises a copolyester.
Claim 7
Dependent Claim
19 words
A receiver sheet according to claim 5 wherein the copolyester comprises a copolymer of ethylene terephthalate and ethylene isophthalate.
Claim 8
Dependent Claim
15 words
A receiver sheet according to claim 1 wherein the substrate is an oriented polyester film.
Claim 9
Independent Claim
106 words
A method of producing a thermal transfer printing receiver sheet having a supporting substrate and a dye-receiving layer for use in association with a compatible donor sheet, comprising forming the supporting substrate, and forming the dye-receiving layer so that said dye-receiving layer is supported by said substrate when in a position associated with said donor sheet to receive a dye thermally transferred from the donor sheet, and wherein said receiving layer comprises a dye-receptive polymer and from 0.5% to 30% by weight of the dye-receiving layer of at least one antiplasticiser therefor, said antiplasticiser comprising at least one aromatic ester of molecular weight not exceeding 1,000.
Claim 10
Independent Claim
106 words
A method of producing a thermal transfer printing receiver sheet having a supporting substrate and a dye-receiving layer for use in association with a compatible donor sheet, comprising forming the supporting substrate, and forming the dye-receiving layer so that said dye-receiving layer is supported by said substrate when in a position associated with said donor sheet to receive a dye thermally transferred from the donor sheet, and wherein said receiving layer comprises a dye-receptive polymer and from 0.5% to 30% by weight of the dye-receiving layer of at least one antiplasticiser therefor, said antiplasticiser comprising at least one aromatic ester of molecular weight not exceeding 1,000.
