Claim:
1. A thermoplastic decorative panel comprising: a copolymerized polyester resin sheet; and at least one decorative material laminated on the copolymerized polyester resin sheet, wherein the decorative material is laminated by applying heat and pressure to the copolymerized polyester resin sheet and the decorative material, and the copolymerized polyester resin sheet is formed with a copolymerized polyester resin having 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 55 to 91 mol % of 1,4-cyclohexanedimethanol and 4 to 40 mol % of isosorbide with respect to the total diol components, wherein the amount of acid is 50 mol % of the total copolymerized polyester resin sheet, wherein a glass transition temperature (Tg) of the copolymerized polyester resin is equal or more than 90° C., izod impact strength thereof is equal or more than 90 J/m, and intrinsic viscosity of the copolymerized polyester resin is equal or more than 0.35 dl/g, and the intrinsic viscosity is measured at the temperature of 35° C. while the copolymerized polyester resin is dissolved with orthochlorophenol to a concentration of 1.2 g/dl, and wherein a thickness of the copolymerized polyester resin sheet is 0.2 to 10 mm.
