Abstract
Radiation curable compositions, comprising, per 100 parts by weight, PA0 (a) at least 20 parts by weight of at least one radiation polymerizable compound containing at least two groups selected from CH.sub.2 .dbd.CH--COO-- and CH.sub.2 .dbd.C(CH.sub.3)--COO-- and PA0 (b) at least 5 parts by weight of at least one (2-oxo-1-pyrrolidinyl)alkyl acrylate or methacrylate of the formula: ##STR1## wherein R represents an alkylene radical containing 2 to 4 carbon atoms and R.sub.1 represents a hydrogen atom or a methyl radical. These radiation curable compositions exhibit a high speed of curing by ultraviolet irradiation or by an accelerated electron beam, and are suitable for the production of coatings with excellent qualities such as good adhesion to the most diverse substrates, a high surface hardness, an improved abrasion resistance and chemical resistance, and good mechanical properties.
