ABSTRACT:
Coating compositions comprising a polyfunctional monomer of a mono or polypentaerythritol poly(meth)acrylate, a bifunctional (meth)acrylate having specific monomer structure, an additional (meth)acrylate containing not more than 2 (meth)acryloyloxy groups, a phosphoric acid ester and an ethanolamine all blended together in a suitable organic solvent system together with a photosensitizer are disclosed. The compositions provide a scratch-resistant, hard cross-linked film surface that is dyeable and resists static and fogging to a synthetic resin article, such as polymethyl methacrylate, to which they are applied.
