Abstract: Provided is an active energy ray curable resin composition for the formation of a hard coating layer on a thermoplastic resin product, where the hard coating layer is one having good resistance to scratches and abrasion and strong resistance to impact and weather or one having very good resistance to scratches and abrasion. The composition contains a urethane (meth)acrylate (A) having an average number of functional groups of 3 to 6 and having, in molecular skeleton, an organic group corresponding to a tricyclodecanedimethanol represented by following Formula (1), except for removing two hydrogen atoms of two hydroxyl groups therefrom; and a microparticulate silica (S) having a volume median diameter of 1 to 100 nm as determined by dynamic light scattering. The composition contains 10 to 40 percent by weight of the urethane (meth)acrylate (A) and 10 to 60 percent by weight of the microparticulate silica (S) based on the total weight of non-volatile matter in the composition.

Abstract: Provided is a compound capable of forming a coating layer that has excellent scratch resistance and still has stain resistance (in particular, stain resistance against hair dyes) and workability (impact resistance) both at satisfactory levels. The urethane (meth)acrylate has a cyclic structure in a molecule. The urethane (meth)acrylate has a total weight of carbon, oxygen, nitrogen, and sulfur atoms constituting the ring or rings of the cyclic structure of 10 percent by weight or more based on the total amount (100 percent by weight) of the urethane (meth)acrylate. The urethane (meth)acrylate also has an average number of functional groups of 3.5 to 4.5.

Abstract: The present invention relates to (meth)acrylated compounds (A) prepared from (a) at least one cyclic ether polyol, (b) at least one linking compound (b1) and/or (b2), wherein the linking compound (b1) is selected from cyclic compounds (b11) containing at least one (I) group in the cycle where X=O or NH, from hydroxy acids (b12) and/or from alkylene oxides (b13) containing from 2 to 4 carbon atoms and the linking compound (b2) is selected from epihalohydrins or polyisocyanates, (c) a (meth)acrylating compound; and to their use in radiation curable compositions for the coatings, inks, overprint varnishes, adhesives and composites.

Abstract: Provided are: a water-absorbing resin composition and a laminate using the resin composition. The resin composition is capable of giving a transparent anti-fog coating excellent in properties such as appearance, coatability, anti-fog properties, water resistance, and heat resistance. Specifically, a resin composition includes a specific (meth)acrylamide copolymer (A) in combination with at least one bifunctional or higher (meth)acrylate compound (B), in which the (meth)acrylamide copolymer (A) is copolymerized from a (meth)acrylamide monomer with another monomer. This resin composition provides an active-energy-ray-curable water-absorbing resin composition and a laminate using the resin composition, each having excellent anti-fog properties.
