Patent ID: 7153892

Claim:
An actinic radiation curable composition having a viscosity between 2–500 cps comprising a mixture of at least one monomer selected from the group consisting of a tetrahydrofurfuryl acrylate, an isobornyl acrylate, a 1,4-butanediol dimethylacrylate, a 2-phenoxyethyl acrylate, a propoxylated glyceryl triacrylate, a trimethylolpropane triacrylate, and a tripropylene glycol diacrylate; at least one free radical photoinitiator; and at least one inorganic nano-filler present in the mixture up to about 17% of the composition by weight; wherein the composition when cured as a coating on a thermoplastic olefin material is an abrasion and scratch resistant coating having at least one property selected from the group consisting of (a) at least 4H hardness; (b) 99+% adhesion; and (c) total light transmittance of 80 to 100% at scattering angles of 0.1 to 10°, wherein the thermoplastic olefin material has not been primed prior to coating with the composition.
