PURPOSE: To cure a hydration cured product such as concrete deposited in a mold frame and at the same time, obtain a stably preservable transfer sheet by constituting the surface of a transfer layer with an uncured or semi-cured thermally curable resin layer in a transfer sheet consisting of an easily peelable transfer layer laminated on a base sheet.
CONSTITUTION: A base sheet 1 is a pliable sheet, for example, an organic, inorganic, synthetic or natural fibrous sheet based on polyolefin such as polyethylene or polypropyrene. A transfer layer 2 should be easily peelable form the base sheet, have a decorative layer, and be adequately adhesive to a hydration cured product. Further, the surface layer 22 of a transfer sheet should be uncured or semi-cured as it becomes adhesive to the hydration cured product adequately during hydration curing process. This thermally curable resin layer 22, exposed on the surface of the transfer sheet, has the high possibility of generating a blocking phenomenon during the preservation of the transfer sheet. To avoid this risk, the thermally curable resin layer 22 contains a filler composed of solid powder. Thus a transfer sheet obtained can be preserved for a long time without the blocking phenomenon.
