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).
