A decorative sheet for three-dimensional processing having a support and at least a surface protective layer laminated thereon, where the decorative sheet for three-dimensional processing has a breaking elongation (according to JIS K 7127) exceeding 300% at temperature higher by 40&#xb0; C. than a thermal deformation temperature of the above support measured by an ASTM D648 method, and the above surface protective layer is obtained by cross-linking and curing an ionizing radiation curable resin composition and has a film thickness of 0.2 to 6.0 &#x3bc;m.

Decorative sheet for three-dimensional work

An antistatic coat of the present invention coats a surface of a base body so as to prevent accumulation of electric charges in the base body, the antistatic coat having a multi-layers structure comprising at least one antistatic layer, and the antistatic layer being disposed between the base body and an outermost surface layer of the antistatic coat. On the back surface side of a thermal transfer sheet, there is formed a heat resistant slip layer through an antistatic layer, or a heat resistant slip layer containing a conductive material. Sulfonated polyaniline, a conductive carbon black having primary particle size of up to 40 nm and specific surface of at least 130 m /g, and a conductive carbon black having an oil absorption of at least 75 ml/100 g are favorable conductive material.
