The present invention provides a resin composition comprising a vinyl polymer (A) having, at a side chain thereof, at least one structure selected from polyether, polyester, polycarbonate or polybutadiene which has a functional group that can react with an isocyanate group, and a polyisocyanate compound (B) having at least two isocyanate groups; a sheet made of a hardened body of the resin composition; a shaped body formed by shaping the sheet; and a sheet producing process comprising the steps of applying the resin composition and then hardening the resultant layer.

A thermal transfer recording method forms a pattern on a marking film, which is a plastic film containing a heat adhesive resin or a plastic film on which a heat-sensitive image-receiving layer, composed mainly of a heat adhesive resin, is formed. A thermal transfer ribbon is prepared by forming a heat-melting ink layer on one surface of a substrate and is used to form the pattern on the marking film. The above method permits the facile formation of a fine or complicated multi-color character or pattern on a marking film in a quick thermal transfer operation at a low cost.
