Abstract: A circumferentially light-emitting thermoplastic resin molded body which can be bent for use according to the type of optical ornaments or the shape of an object to be decorated and which allows the overall luminance of the emitted light to improve and restrains the luminescent color from being yellowed at the distal locations of such body with regard to the light source. The thermoplastic resin molded body has a core layer made from a thermoplastic elastomer; and a first clad layer made from a thermoplastic resin whose refractive index is smaller than the thermoplastic elastomer from which the core layer is made, in which a light diffusing agent is added to the thermoplastic elastomer from which the core layer is made and the thermoplastic resin from which the first clad layer is made respectively; and the total light transmittance of the first clad layer is defined as less than 70%.

Abstract: The invention provides a laminating acrylic thermoplastic polymer composition which is favorably laminated together with a layer including a plasticizer-containing polymer composition while ensuring that the migration of the plasticizer into the acrylic thermoplastic polymer composition layer is small and the resultant laminate attains excellent durability, and also provides a laminate obtained by laminating a layer including the laminating acrylic thermoplastic polymer composition onto one or both sides of a layer including the plasticizer-containing polymer composition. Further, the invention provides a polymer composition which, when the plasticizer-containing polymer described above is a vinyl chloride-based polymer, can keep sufficient adhesive force after being adhered to a layer including such a vinyl chloride-based polymer, and also provides an adhesive product using the composition. The laminating acrylic thermoplastic polymer composition is a composition for lamination with a layer including a plasticizer-containing polymer composition. The acrylic thermoplastic polymer composition includes an acrylic block copolymer (I) including at least one polymer block (A) containing methacrylic acid ester units and at least one polymer block (B) containing acrylic acid ester units; and the acrylic acid ester units constituting the polymer block (B) in the acrylic block copolymer (I) include an acrylic acid ester (1) unit represented by the general formula CH2═CH—COOR1 (1) (wherein R1 is an organic group having 1 to 3 carbon atoms).
