PROBLEM TO BE SOLVED: To obtain a polyester sheet having improved slipperiness without impairing transparency and impact resistance of a drawn molding and its molding. SOLUTION: The unoriented multilayer polyester sheet for drawing comprises a core layer made of polyester, and skin layers each containing 0.01 to 5 wt.% of spherical silicone resin having a mean particle size of 1 to 7 m and obtained by bonding at least one type of a basic structure represented by -(SiO(2-x/2) Rx )- (where R is 1-4C alkyl group, and x is integer of 1 to 3), and 95 to 99.99 wt.% of polyester and laminated on both surfaces of the core layer. |
