ABSTRACT:
A process for producing an adhesive tape with single- or double-sided crosslinked pressure-sensitive acrylate hotmelt adhesive layer, wherein a crosslinker is added in the melt to a polyacrylate copolymer (“polyacrylate”) based on acrylic and/or methacrylic esters, the polyacrylate with crosslinker is conveyed to a coating unit, where it is applied to a web-form layer and following application is homogeneously crosslinked, where the crosslinker is a thermal crosslinker and some of the acrylic and/or methacrylic esters contain primary hydroxyl groups and addition takes place preferably in an extruder.
