Abstract
Radiation-curable compositions including a free radically polymerizable monomer or prepolymer and a different monomer containing an N-vinyl group, said different monomer being a solid at ambient temperature. The different monomer is preferably N-vinyl caprolactam, N-vinyl carbazole, or N,N'-divinyl-2-imidazolidone, for example in an amount of from 1 to 50 percent by weight of the said different monomer. Such compositions have shown good adhesion to and have rendered plastics substrates wettable by the compositions before curing, without the presence of N-vinyl-2-pyrrolidone.
