Abstract
The present invention provides a resin composition comprising 50 to 99 percent by weight of a completely amorphous polyester resin (A), and 1 to 50 percent by weight of a graft copolymer (B) obtained by graft-polymerizing a methacrylic acid ester and a vinyl aromatic compound with conjugated diene rubber particles and/or a graft copolymer (C) obtained by graft-polymerizing a methacrylic acid ester and a vinyl aromatic compound with acrylic rubber particles. According to the present invention, a resin composition and a resin sheet specifically suitable for membrane pressing, vacuum pressing, air pressing, and the like are provided, in which the resin composition and the resin sheet have superior properties, such as workability, moldability, impact resistance, transparency, and the like. In addition, plate-out is not significantly observed and whitening during embossing and heat-sealing is unlikely to occur.
