摘要： The present invention provides a curable composition which has a viscosity suitable for spray coating even at a high solid content and from which a cured product, on which precipitation of an ultraviolet absorber is suppressed and which has excellent weatherability and hot water resistance, is obtained, a cured product using the curable composition, and a stacked body.
Provided is a curable composition including: a (meth)acrylate A; a urethane (meth)acrylate B; an ultraviolet absorber C; and a photopolymerization initiator D, in which the (meth)acrylate A has at least one of a dendrimer structure and a hyperbranched structure, a content of the (meth)acrylate A is 55 parts by mass to 95 parts by mass based on 100 parts by mass in total of the (meth)acrylate A and the urethane (meth)acrylate B, a content of the ultraviolet absorber C is 1.5 parts by mass to 60 parts by mass based on 100 parts by mass in total of the (meth)acrylate A and the urethane (meth)acrylate B, a solid content concentration of the curable composition is greater than or equal to 70 mass %, and a viscosity of the curable composition at 25° C. which is measured with an E-type viscometer is less than or equal to 200 mPa·s.
