Coated polycarbonate articles, such as sheet and film, are coated with a hard, abrasion and chemical resistant coating which is the photoreaction product of an acrylated urethane oligomer, a difunctional acrylate monomer and preferably also a monofunctional olefinic monomer. These coated articles may be thermoformed or flexed without cracking or delamination of the protective coating. A specific embodiment of the invention is a coated flexible siloxane-polycarbonate block copolymer.

Coated polycarbonate articles

Coated article has a thermoplastic substrate and a surface coating of a transparent ultraviolet light-resistant polymer which is the reaction product of a melamine compound, a polyol, and a multimeric benzotriazole compound. The coating of the coated article retains its UV absorbance during curing and exposure to elevated temperatures.

Photocurable acrylic coating composition

A photocured acrylic coat comprised of the photoreaction products of:

Novel coating compositions contain a radiation polymerizable acrylic monomer or oligomer and an ultraviolight-light absorbing effective amount of a UV-absorbing multimeric benzotriazole compound.

UV-stabilized coatings

A protective coating composition containing certain polyester polyols and an aminoplast derivative is applied to a thermoplastic substrate to produce a thermoformable article having mar- and solvent-resistance.

Melamine based protective coatings for thermoplastic substrates

A protective coating composition containing a polycaprolactone polyol and an aminoplast derivative is applied to a thermoplastic substrate to produce a thermoformable article having abrasion resistance, solvent resistance and weatherability.

Weatherable abrasion resistant etherified aminoplast derived coating for

Polymeric substrates, especially the polycarbonates, are coated with a photocurable coating mixture containing polyfunctional acrylates, acrylonitriles, and a photoiniator to produce scratch- and mar-resistant polymeric articles.

Photocurable acrylate-acrylonitrile coated plastic articles

Photocurable compositions are provided based on the use of a triarylsulfonium salt photoinitiator to effect the free-radical cure of particular organic resins, such as an acrylic. A free-radical curing method is also provided for a broad variety of aliphatically unsaturated materials including mixtures of styrene and unsaturated polyesters.

Free radical curable resin compositions containing triarylsulfonium salt

A polycarbonate article having an adherent mar, abrasion and chemical resistant ultraviolet light cured coating on the surface thereof comprised of the photoreaction products of certain polyfunctional acrylate monomers and certain acrylate modified polymers.

Photocurable acrylic coated polycarbonate articles

A polycarbonate article having a durably adherent mar, abrasion and chemical resistant UV cured coating on the surface thereof comprised of the photoreaction products of (i) certain polyfunctional acrylate monomers and (ii) resorcinol monobenzoate.

Ultraviolet resistant transparent coatings are provided formed of (A) a melamine nucleus compound, (B) a benzophenone and preferably (C) a polyol. The compositions are effective in protecting polycarbonate resins and other UV degradable materials.

Melamine coatings

A method is provided for making a thermoformable composite involving the treatment of at least one of the major surfaces of a thermoplastic substrate, such as a sheet, with a solventless ultra-violet (UV) curable organic resin, followed by the UV-curing of the resin. The cured resin provides an adherent decorative and/or protective coating having desirable biaxial elongation characteristics.
