    Abstract: Disclosed are urethane (meth)acrylates obtainable by implementation of the following steps: (r1) partially reacting an alkoxylated polyol (A) with (meth)acrylic acid (B) in the presence of at least one esterification catalyst (C) and at least one polymerization inhibitor (D) and also, optionally, of a solvent (E) that forms an azeotrope with water, (o1) optionally removing at least some of the water formed in r1) from the reaction mixture, it being possible for o1) to take place during and/or after r1), (o2) optionally neutralizing the reaction mixture, (o3) if a solvent (E) has been used, optionally removing this solvent by distillation and/or (o4) stripping with a gas which is inert under the reaction conditions, (r2) reacting the reaction mixture obtained after the last of the above reaction steps with a compound (G) containing at least two epoxy groups, optionally in the presence of a catalyst (H), and (r3) reacting the reaction mixture from (r2) with at least one polyisocyanate (J) and at least one hydroxyalkyl (meth)acrylate (K) and optionally with at least one further compound (M) which contains one or more isocyanate-reactive groups, in the presence of a catalyst (L), with the proviso that the catalyst (L) used in step (r3) is a bismuth-containing catalyst.

    Abstract: A heat transfer film having a) a carrier film, b) at least one coating layer arranged directly on the carrier film, and c) at least one hot-sealable polymer adhesive layer is disclosed. The coating layer is based on a non-aqueous, radiation-curable, liquid composition which contains at least 60 wt %, based on the total weight of the composition, of curable constituents selected from organic oligomers which have ethylenically unsaturated double bonds. Use of the heat transfer films for the dry coating of surfaces, production of such heat transfer films, and methods for coating or lacquering surfaces of objects using the heat transfer films are also disclosed.

    Abstract: The present invention relates to heat transfer films, comprising: a) a carrier film (2), b) at least one, for example one, two or three, coating layer(s) (3) arranged directly on the carrier film (2), c) at least one, in particular precisely one, hot-sealable polymer adhesive layer (4), wherein the coating layer is based on a non-aqueous, radiation-curable, liquid composition which contains at least 60 wt %, in particular at least 70 wt %, based on the total weight of the composition, curable constituents selected from organic oligomers which have ethylenically unsaturated double bonds and mixtures of these oligomers with monomers which have at least one ethylenically unsaturated double bond. The invention also relates to the use of the heat transfer films for the dry coating of surfaces. The invention also relates to the production of such heat transfer films and to a method for coating or lacquering surfaces of objects using the heat transfer films according to the invention.
