Disclosed is an active energy ray-curing composition containing an active energy ray-curing prepolymer (A) obtainable by a reaction of an acrylic-based prepolymer having a hydroxyl group and an acrylic monomer (a4) having an isocyanate group, an active energy ray-curing compound (B) having a benzotriazole group, another active energy ray-curing compound (C) differing from the (A) component and the (B) component, and inorganic oxide particles (D). The acrylic-based prepolymer having the hydroxyl group is a copolymer that includes an acrylic monomer (a1) having a piperidinyl group, an acrylic monomer (a2) having a hydroxyl group, etc., as monomer units.

Actinic-light-curable composition, molded polycarbonate resin object with a cured film, and manufacturing method therefor

Disclosed is a vehicle member that includes a molded body and a protective film disposed on a surface of the molded body and formed by curing of an active energy ray-curing composition. The active energy ray-curing composition contains an active energy ray-curing prepolymer (A) obtainable by a reaction of an acrylic-based prepolymer having a hydroxyl group and an acrylic monomer (a4) having an isocyanate group, an active energy ray-curing compound (B) having a benzotriazole group, another active energy ray-curing compound (C) differing from the (A) component and the (B) component, and inorganic oxide particles (D). The acrylic-based prepolymer having the hydroxyl group is a copolymer that includes an acrylic monomer (a1) having a piperidinyl group, an acrylic monomer (a2) having a hydroxyl group, etc., as monomer units.

Vehicle member and manufacturing method therefor

An ink curable with actinic energy rays characterized by containing a photocleavage type photopolymerization initiator (A) comprising &#x3b1;-aminoalkylphenone compound (A1) having a molar absorption coefficient measured at a wavelength of 363 nm of 100 (l/mol&#xb7;cm) or more and less than 100,000 (l/mol&#xb7;cm) and/or an acylphosphine oxide compound (A2) having a molar absorption coefficient measured at a wavelength of 365 nm of 100 (l/mol&#xb7;cm) or more and less than 100,000 (l/mol&#xb7;cm); and a hydrogen abstraction type photopolymerization initiator (B) comprising 4,4'-dialkylaminobenzophenone having a molar absorption coefficient at a wavelength of 365 nm of 10,000 (l/mol&#xb7;cm) or more and less than 1,000,000 (l/mol&#xb7;cm) and by optionally containing a tertiary amine compound (C) having a molar extinction coefficient as measured at a wavelength of 365 nm of 1 (l/mol&#xb7;cm) or lower. The ink further includes a resin, a pigment, and a compound having an acrylate group.

Ink curable with actinic energy ray and printed matter

An active energy ray-curable resin composition comprises a compound (A) having an active energy ray-curable unsaturated bond in a molecule, an anti-staining property-imparting agent (B) which is a fluorine-containing polyether compound having a perfluoropolyether unit, a urethane bond and an active energy ray-curable unsaturated bond in a molecule, a compound (C) represented by the general formula (I): wherein R1, R2 and R3 may be either the same or different, and are respectively an organic group having at least one functional group selected from the group consisting of a vinyl group, an epoxy group, a (meth)acryloxy group, an amino group and a mercapto group, and n is an integer of 0 or more; and inorganic fine particles (D).
