Abstract
A thermoplastic molded product including a decorative material having superior heat resistance, impact strength and flexural strength is disclosed. The thermoplastic molded product is useful for a window glass substitute, a partition, a decorative panel, a decorative film, and so on. The thermoplastic molded product comprises a copolymerized polyester resin sheet made of a copolymerized polyester resin; and at least one decorative material laminated on the copolymerized polyester resin sheet, the lamination being performed by applying heat and pressure to the copolymerized polyester resin sheet and the decorative material. The copolymerized polyester resin has an alternating structure of acid moieties which are derived from acid components and diol moieties which are derived from diol components, and the acid components comprise terephthalic acid, and the diol components comprise (i) 5˜99 mol % of 1,4-cyclohexanedimethanol and (ii) 1˜60 mol % of isosorbide with respect to the total diol components.
