Abstract

The present invention relates to a UV-curable hot-melt adhesive for laminating transparent films, in particular, on molded bodies made of wood materials that are coated with melamine or PVC. The hot-melt adhesives contain: at least one UV-curable urethane (meth)acrylate, wherein the urethane (meth)acrylate can be obtained by converting an NCO-functional polyurethane prepolymer with a molar excess of hydroxy and/or amine-modified (meth)acrylates; at least one (meth)acrylate monomer or oligomer, wherein the at least one (meth)acrylate monomer and/or oligomer comprises an acid-modified (meth)acrylate with an acid value of 50 to 400 mg KOH/g; and at least one photoinitiator. Other aspects of the present invention are methods for laminating a film onto a molded body using said hot-melt adhesives, and to the composite materials produced in this manner.
