Abstract

A thermal transfer recording material for imparting metallic luster, comprising: a substrate; and at least a layer having metallic luster and optionally an adhesive layer provided in that order on one surface of the substrate, an ink-receptive layer being provided between the layer having metallic luster and the substrate.

Claims

1. A thermal transfer recording material for imparting metallic luster, comprising:

a substrate; and

at least an anchor layer for deposition, a deposited metal layer, and an adhesive layer provided in that order on one surface of the substrate,

the adhesive layer containing wax and, in addition, at least one component selected from the group consisting of an ethylene/acrylic acid copolymer, an ethylene/methacrylic acid copolymer, and an ethylene/vinyl acetate copolymer, said least one component having a weight-average molecular weight of from 5,000 to 15,000.

2. The thermal transfer recording material according to claim 1, wherein the total content of at least one component selected from the group consisting of an ethylene/acrylic acid copolymer, an ethylene/methacrylic acid copolymer, and an ethylene/vinyl acetate copolymer is 10 to 50% based on the total weight of the adhesive layer.

3. A record having metallic luster, comprising an image recorded using a thermal transfer recording material according to claim 1.

4. A record having metallic luster, comprising an image as a halftone record formed by taking advantage of area gradation using a thermal transfer recording material according to claim 1.
