-15. (canceled)
A layer construction comprising
- at least one layer (A) comprising at least one thermoplastic and
- at least one layer (B) comprising a polyester component comprising at least one poly- or copolycondensate of terephthalic acid or naphthalenedicarboxylic acid,
- wherein the polyester component has radicals of cyclohexane-1,4-dimethanol in an amount of from 25 to 75 mol %, based on the radicals of the diol component(s) in all the poly- or copolyesters which the polyester component comprises.
A single- or multilayer film of plastic comprising at least one layer comprising a polyester component comprising at least one poly- or copolycondensate of terephthalic acid or naphthalenedicarboxylic acid, wherein the polyester component has radicals of cyclohexane-1,4-dimethanol in an amount of from 25 to 75 mol %, based on the radicals of the diol component(s) in all the poly- or copolyesters which the polyester component comprises.
