摘要： The present invention provides a synthetic resin laminate, which is excellent in terms of shape stability in a high-temperature or high-humidity environment, surface hardness, heat resistance, coating adhesion and the like. The synthetic resin laminate is formed by laminating a resin layer (A) including 5% to 55% by mass of a (meth)acrylate copolymer (C) and 95% to 45% by mass of a polycarbonate (D) on one surface or both surfaces of a base material layer (B) comprising polycarbonate, wherein the synthetic resin laminate is characterized: in that the (meth)acrylate copolymer (C) includes an aromatic (meth)acrylate unit (c1) and a methyl methacrylate unit (c2) at a mass ratio (c1/c2) of 5 to 80/20 to 95; in that the mass average molecular weight of the (meth)acrylate copolymer (C) is 5,000 to 30,000; and in that the viscosity average molecular weight of the polycarbonate (D) is 21,000 to 40,000.

摘要： A synthetic resin laminated sheet, in which whitening, cracking, and foaming do not occur when thermoforming is carried out, in particular when deep-draw molding is carried out, and defects do not occur during lamination of a hard coating layer; and a molded article obtained by molding the laminated sheet. A synthetic resin laminated sheet has a coating layer, which includes an acrylic resin, laminated on one surface of a substrate layer including a polycarbonate resin in which a monohydric phenol represented by general formula (1) is used as a chain terminator and is obtained by reacting the monohydric phenol with a dihydric phenol and a carbonate binding agent and has a viscosity average molecular weight of 18000-35000. (In the formula, R1 represents a C8-36 alkyl group or a C8-36 alkenyl group. R2-R5 each represent hydrogen, halogen, or an optionally substituted C1-20 alkyl group or C6-12 aryl group).

摘要： It is an object of the present invention to provide a synthetic resin laminate for use in transparent substrate materials or transparent protective materials, having excellent shape stability and surface hardness. This has been achieved by laminating a resin composition formed by polymer-alloying i) 25% to 100% by mass of a specific styrene-unsaturated dicarboxylic acid copolymer consisting of 45% to 70% by mass of a styrene monomer unit, 10% to 30% by mass of an unsaturated dicarboxylic acid anhydride monomer unit, and 10% to 35% by mass of a vinyl monomer, and ii) 75% to 0% by mass of a resin comprising a vinyl monomer as a constitutional unit, on one surface of a base material layer comprising a polycarbonate as a main component. Thus, the present invention provides the above-described synthetic resin laminate, a transparent material comprising the synthetic resin laminate, and the like.

摘要： Provided is a cellulose solution (a composition) in which decomposition of cellulose does not easily proceed even if heated. Further, provided is a method for producing a cellulose fiber excellent in mechanical strength. The composition includes cellulose and a compound represented by the following formula (1), a concentration of 1-methylimidazolium chloride being 300 ppm or less on a mass basis with respect to the compound represented by the formula (1).
In the formula (1), R is an alkyl group having 2 to 6 carbon atoms, and Me is a methyl group.
