A photocured acrylic coat comprised of the photoreaction products of: PA0 (i) at least one photocurable polyfunctional acrylate monomer; PA0 (ii) at least one phenyl ketone photoinitiator; and PA0 (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 ultraviolet radiation. The coating is also nonopaque or transparent.
