Abstract: A resin composite that excels in weatherability and transparency and experiences less bleed out and whitening at a high temperature, and a method for producing the resin composite, and the like are provided. Specifically, the resin composite includes: a methacrylic resin (A) that contains a structural unit derived from methyl methacrylate and that has a melt viscosity η(A) of 1,500 to 3,500 Pa·s; and a block copolymer (B) in which a methacrylic acid ester polymer block (b2) is coupled to an acrylic acid ester polymer block (b1). The block copolymer (B) has a melt viscosity η(B) of 75 to 1,500 Pa·s. A ratio η(A)/η(B) is from 1 to 20. 0.1 to 3 parts by mass of a hydroxy phenyl triazine-based UV absorber is contained in 100 parts by mass of the total of the methacrylic resin (A) and the block copolymer (B).

Abstract: Provided is a thermoplastic resin composition that can be firmly bonded to an adherend with an active energy ray-curable adhesive provided therebetween, and provided are a molded product and a film each including such a thermoplastic resin composition. Also provided are a thermoplastic resin composition that is less likely to be whitened even when the adhesive permeates thereinto and a molded product and a film each including such a thermoplastic resin composition. The thermoplastic resin composition according to the present disclosure contains 70 to 95 mass % of a thermoplastic resin and 5 to 30 mass % of a multilayer structure polymer (C) having a multilayer particle structure, and the multilayer structure polymer (C) has a median diameter Da of no less than 200 nm and less than 500 nm when the median diameter Da is measured through a laser diffraction/scattering technique with the thermoplastic resin composition dissolved in acetone.

Abstract: A resin composite, a method of producing the resin composite, a molded product, a film, and an article excellent in impact resistance are provided. The resin composite contains a methacrylic resin (A), which contains no less than 80% by mass of a structural unit derived from methyl methacrylate and has a melt viscosity η(A) of 1500 to 3500 Pa·s at 220° C. and a shear rate of 122/sec, and a triblock copolymer (B), which has a methacrylic acid ester polymer block (b2) coupled to each of two ends of an acrylic acid ester polymer block (b1), at a specific ratio. The triblock copolymer (B) includes the block (b1) and the block (b2) at a specific ratio and has a melt viscosity η(B) of 75 to 1500 Pa·s at 220° C. and a shear rate of 122/sec. The ratio of η(A)/η(B) is from 1 to 20.
