Abstract

Solid compositions comprising(A) at least one solid (meth)acrylate copolymer with a number-average molecular weight of from 850 to 10 000 and a molecular weight polydispersity Mw/Mn of from 1.0 to 5.0, containing at least one group (a) having at least one bond which can be activated with actinic radiation; and(B) at least one solid compound comprising a parent structure and, attached thereto, on average per molecule more than one group (a) having at least one bond which can be activated with actinic radiation;and their use as coating materials, adhesives or sealing compounds which can be crosslinked thermally and/or with actinic radiation, or for preparing coating materials, adhesives or sealing compounds which can be crosslinked thermally and/or with actinic radiation.
