Abstract: The sensitivity, diffraction efficiency, etc. of hologram recording materials is improved. Disclosed is a resin composition for a hologram recording material, the resin composition comprising: a photosensitive component comprising (a) a monomer having a vinyloxy group, (b) a compound having a (meth)acryloxy group, and (c) a photopolymerization initiator; and a prepolymer component, wherein the component (a) is designed so as to be relatively higher or lower in refractive index than the prepolymer component.

Abstract: It is an object of the present invention to provide a clear coating composition which is desirably controllable for sagging prevention and can form a coating film having various physical properties such as smoothness, good appearance, weather resistance, and water resistance required as a clear coating film and a clear coating film formation method using the coating composition. A clear coating composition containing a UV curable compound (U-1) having an unsaturated bond, a photopolymerization initiator (U-2), a half ester group-containing acrylic copolymer (A-1), and an epoxy group-containing acrylic copolymer (A-2).
