Abstract
Abstract Ultraviolet light curable coating compositions comprising (1) a monomer and/or prepolymer containing at least one radically crosslinkable ethylenically unsaturated double bond and (2) a photopolymerization initiator containing (a) 4,4'-bis(diethylamino)benzophenone and (b) a lower alkyl ester of p- or o-benzoylbenzoic acid or a derivative thereof in a weight ratio of (a) to (b) of 1 : 1 to 1 : 10.
