Abstract:
A photocurable resin compound sheet comprising a photocurable resin compound (i) containing as an essential component at least one unsaturated resin (A) selected from the group consisting of unsaturated polyester resin, vinyl ester resin, vinyl urethane resin, and acrylic resin, a photopolymerization initiator (B) which is not activated by irradiation with light with a wavelength of 420 nm or above, and a thickener (C) containing a thermoplastic resin powder as an active component; and a see-through light absorbing film (ii) whose transmittance to, light with a wavelength of 420 nm or below is 10% or less; said photocurable resin compound being covered with said see-through light absorbing film, wherein the resin compound is protected from light exposure to prevent photopolymerization and partial photocuring of the resin compound, and wherein said photocurable resin compound (i) is prepared by combining said unsaturated resin (A), said photopolymerization initiator (B) and said thickener (C) in the absence of a photopolymerization initiator which is activated by irradiation with light with a wavelength of 420 nm or more.
