Embodiments provide an active energy curable resin composition containing (A) 100 parts by mass of a UV-absorbing polymer and (B) 20-600 parts by mass of a polyfunctional (meth)acrylate. The UV-absorbing polymer (A) contains: (a1) 10-60 mol % of a structural unit derived from a (meth)acrylate including one or more of one or more types of backbone selected from the group consisting of a benzotriazole backbone, a triazine backbone, and a benzophenone backbone per molecule; (a2) 10-50 mol % of a structural unit derived from an alkyl (meth)acrylate; and (a3) 10-70 mol % of a structural unit derived from a compound including one or more isocyanate groups per molecule; the sum of the structural unit derived from a (meth)acrylate of component (a1), the structural unit derived from an alkyl (meth)acrylate of component (a2), and the structural unit derived from an isocyanate-group-including compound of component (a3) being 100 mol %.

Embodiments provide a packing box whereby strength is improved and efficiency of opening, content retrieval, etc. is improved. Embodiments provide a packing box obtained from an upper cover and a lower box configured from cardboard for accommodating articles therein, in which: the upper cover is obtained from a top board that covers the entire interior of the lower box and side boards that extend vertically downward from each side of the top board and substantially covers the side surfaces of the lower box; and at least one notch is provided on one of the lower edges of the upper cover.

The present invention provides a resin composition comprising 50 to 99 percent by weight of a completely amorphous polyester resin (A), and 1 to 50 percent by weight of a graft copolymer (B) obtained by graft-polymerizing a methacrylic acid ester and a vinyl aromatic compound with conjugated diene rubber particles and/or a graft copolymer (C) obtained by graft-polymerizing a methacrylic acid ester and a vinyl aromatic compound with acrylic rubber particles. According to the present invention, a resin composition and a resin sheet specifically suitable for membrane pressing, vacuum pressing, air pressing, and the like are provided, in which the resin composition and the resin sheet have superior properties, such as workability, moldability, impact resistance, transparency, and the like. In addition, plate-out is not significantly observed and whitening during embossing and heat-sealing is unlikely to occur.

Resin composition and resin sheet

A decorative laminated sheet, sequentially comprising (A) a completely amorphous polyester resin layer and (B) a substrate layer composed of a polyolefin resin, a polyvinyl chloride resin, an acrylonitrile-butadiene-styrene resin, an acrylonitrile-styrene-acrylic acid ester resin, an acrylonitrile-ethylene propylene-styrene resin, a methyl methacrylate-butadiene-styrene resin, a polyethylene terephthalate or a completely amorphous polyester resin. Or a decorative laminated sheet comprising a substrate layer composed of (B) a completely amorphous polyester type resin layer and a transfer foil formed thereon.
