A plastic substrate having deposited on at least one surface thereof a photocured acrylic coat-comprised of the photoreaction products of:
(i) at least one photocurable polyfunctional acrylate monomer;
(ii) at least one phenyl ketone photoinitiator; and
(iii) at least one active ultraviolet radiation absorber selected from benzotriazoles, cyanoacrylates, and hydroxybenzophenones. The coating is substantially completely or completely cured and provides improved protection to the substrate against ultarviolet radiation. The coating is also non-opaque or transparent.
