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： An optical sheet is formed by laminating, by co-extrusion molding, a first layer containing a polycarbonate resin, a second layer containing a polyamide resin, and a third layer, wherein the second layer is laminated between the first layer and the third layer, the first layer and second layer, and the second layer and third layer can each be peeled at the interface, and the outer surface of the first layer has a fine grooved structure. The optical sheet, which is provided with a plurality of layers in such a way, is capable of retaining, a sufficient amount of heat in a laminate in a mold since the entire sheet can be made thick during melt extrusion molding, and is able to improve the transferability of the fine grooved structure. In addition, the optical sheet can be made thinner by using only the peeled first layer as an optical sheet.

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.
