Patent ID: 10190021

Abstract:
There is provided a floor coating composition used for coating of a floor, which has improved performance and durability without a boundary between the cured and uncured areas. Also provided is a floor coating composition for flooring material, which contains components (A) to (E) below as essential components: component (A): a bifunctional (meth)acrylate compound not having an alicyclic structure; component (B1): a trifunctional or more urethane (meth)acrylate oligomer; component (B2): a hexafunctional or more urethane (meth)acrylate oligomer other than the component (B1); component (C): a melamine (meth)acrylate; component (D): metal oxide nanoparticles; and component (E): an active energy ray polymerization initiator. The amount of component (A) contained is more than 24 weight % and less than 50 weight %, the amount of component (B1) contained is more than 10 weight % and less than 35 weight %, and the amount of component (C) contained is not less than 10 weight % and less than 20 weight %, and component (E) contains a hydrogen abstraction photopolymerization initiator.
