PURPOSE: A polyester film for decoration sheet and manufacturing method thereof are provided to put pigments into a co-polymerized polyester layer to improve thickness uniformity, adhesion force, moldability, shielding property, and coloring capability. CONSTITUTION: A polyester film for decoration sheet comprises a polyester layer(B) and copolymerized polyester layer(A). The polyester layer(B) comprises a first component consisting of repeat units of dicarbonic acid and diol, and a 95mol% second component selected from dicarbonic acid and diol. The copolymerized polyester layer(A) contains pigments, the first component consisting of repeat units of dicarbonic acid and diol, and the 95mol% second component selected from dicarbonic acid and diol. The polyester layer(B) and copolymerized polyester layer(A) are laminated. |
