Abstract
Pressure-sensitive adhesives composed of radiation-cured (meth)acrylic-functional polyesters are prepared from base polyesters, fluid at room temperature, which have molecular weights of 1,000 to 10,000 and branched main chain, and/or from new polyesters having aliphatic side chains bound by ester bridges or, in some cases, ether bridges to the main chain, followed by functionalization of a maximum of 90% of the original hydroxyl groups of the base polyesters by reaction with (meth)acrylate compounds, and crosslinked by electron beam or ultraviolet radiation in a thin coating on a support. The new pressure-sensitive adhesives have the property and the advantage of being cross-linkable by radiation without the use of solvents or diluents.
