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: Provided are an active energy ray-curable composition fox flooring materials, which is unlikely to cause a curing defect between a cured portion and an uncured portion even when a movable curing device having a light source is used is unlikely to cause yellowing attributable to exposure to natural light for a long period of time, and exhibits a high re-coatability, while exhibiting conventional physical performance, and a construction method therefor. Further, also provided are an active energy ray-curable composition for antibacterial flooring materials, which has antibacterial properties, and a construction method therefor. The active energy ray-curable composition for flooring materials is formed by appropriately applying a specific carboxyl group-containing active energy ray-polymerizable compound, a specific urethane oligomer, a specific hyperbranched oligomer, specific polyfunctional acrylate, and a specific photopolymerization initiator in combination.

Abstract: Provided is an active energy ray-curable composition for flooring materials, which more strongly adheres to flooring materials that contain vinyl chloride while maintaining conventional physical performance. Specifically provided is an active energy ray-curable composition for flooring materials, which contains an active energy ray-polymerizable compound and a photopolymerization initiator, wherein the active energy ray-polymerizable compound includes a polyvinyl chloride-insoluble compound (A) which does not dissolve or does not substantially dissolve in polyvinyl chloride and a polyvinyl chloride-soluble compound (B) which dissolves in polyvinyl chloride, and the content of the compound (B) is in a range of 3% to 40% by weight with respect to the content of the compound (A).
