Abstract
A coating composition comprising a radiation curable oligomer and a reactive diluent having the formula: ##STR1## wherein R' is a monovalent aromatic or alkyl radical including from 4 to about 20 carbon atoms, R.sup.2 is a divalent alkyl radical including from about 2 to about 4 carbon atoms, and R.sup.3 is hydrogen or methyl. Addition of the reactive diluent not only reduces the viscosity of the uncured composition to an acceptable value for use as a coating but also surprisingly increases the elongation of the cured coating without reducing its tensile strength. Superior coatings for floor tiles, flooring, and other applications are thus provided.
