Abstract: The present invention provides an energy curable coating composition comprising a carboxylic acid functional acrylate monomer, a polyester acrylate oligomer and at least one further oligomer. Furthermore the present also provides a process for preparing a coated substrate, in particular a flooring substrate which comprises applying an energy curable coating composition onto a substrate and curing the composition. The composition provides improved flow and leveling characteristics and a coating with high degree of scratch resistance.

Abstract: The present invention describes a method for repairing defects on a surface of an optical substrate. The method includes a step of providing a radiation curable coating and then applying the coating onto a surface of the optical substrate. The coating is then cured with a UV light source causing the refractive index of the coating to be less than ±10% of the refractive index of the substrate. The cured coating exhibits a viscosity less than about 315 CP at 25° C. The present invention also describes a novel coating composition for repairing optical substrates.
