Abstract

Abstract Disclosed is a novel thermoplastic article having a high-relief, molded or embossed surface produced by contacting a laminate comprising a first or outer copolyester sheet material and a second or backing copolyester sheet material with heat and pressure using a heated element which simultaneously causes the material to be bonded and a high-relief, decorative appearance to be produced on at least one surface of the thermoplastic article. Also disclosed is an embossed or molded, bonded laminate comprising, in order, (1) a first or outer copolyester layer, (2) a second layer comprising a film which is colored or which bears an image or pattern, and (3) a third or backing copolyester layer, wherein the first and third layers are composed on the above-described copolyester. The copolyesters of the thermoplastic articles and laminates are selected from copolyesters having an inherent viscosity of 0.5 to 1.2 dL/g, when measured at 25° C. using 0.50 grams of polymer per 100 mL of a solvent consisting of 60 weight percent phenol and 40 weight percent tetrachloroethane, comprising (i) diacid residues comprising at least 80 mole percent terephthalic acid residues; and (ii) diol residues comprising from 98 to 1 mole percent ethylene glycol residues and from 2 to 99 mole percent residues derived from 1,3- or, preferably, 1,4-cyclohexanedimethanol in which the ethylene glycol and cyclohexanedimethanol residues constitute at least 80 mole percent of the diol residues.

Claims Analysis

Total Claims: 11
Claim 1
Independent Claim 168 words
A thermoplastic article having a high-relief, molded or embossed surface obtained by contacting a laminate comprising a first sheet material and a second sheet material with heat and pressure using a heated element which results in the simultaneous bonding of the sheet material and the production of a decorative texture or design on the surface of at least one of the sheets; wherein the first and second sheet materials are formed from a copolyester having an inherent viscosity of 0.5 to 1.2 dL/g, when measured at 25° C. using 0.50 grams of polymer per 100 mL of a solvent consisting of 60 weight percent phenol and 40 weight percent tetrachloroethane, comprising: (i) diacid residues comprising at least 80 mole percent terephthalic acid residues; and (ii) diol residues comprising from 98 to 1 mole percent ethylene glycol residues and from 2 to 99 mole percent residues derived from 1,3- or, 1,4-cyclohexanedimethanol in which the ethylene glycol and cyclohexanedimethanol residues constitute at least 80 mole percent of the diol residues.
Claim 2
Dependent Claim 168 words
A thermoplastic article having a high-relief, molded or embossed surface obtained by contacting a laminate comprising a first sheet material and a second sheet material with heat and pressure using a heated element which results in the simultaneous bonding of the sheet material and the production of a decorative texture or design on the surface of at least one of the sheets; wherein the first and second sheet materials are formed from a copolyester having an inherent viscosity of 0.5 to 1.2 dL/g, when measured at 25° C. using 0.50 grams of polymer per 100 mL of a solvent consisting of 60 weight percent phenol and 40 weight percent tetrachloroethane, comprising: (i) diacid residues comprising at least 80 mole percent terephthalic acid residues; and (ii) diol residues comprising from 98 to 1 mole percent ethylene glycol residues and from 2 to 99 mole percent residues derived from 1,3- or, 1,4-cyclohexanedimethanol in which the ethylene glycol and cyclohexanedimethanol residues constitute at least 80 mole percent of the diol residues.
Claim 3
Dependent Claim 41 words
