<p><P>PROBLEM TO BE SOLVED: To provide a thermoplastic resin composition that contains a methacrylic resin (A) and a polyvinyl acetal resin (B), by which a molded product and a film can be stably and reproducibly produced which are excellent in transparency and hue, are less likely to cause defects such as fisheye, and are excellent in surface smoothness. <P>SOLUTION: The acrylic thermoplastic resin composition comprises: the methacrylic resin (A); the polyvinyl acetal resin (B) obtained by acetalizing a polyvinylalcohol resin with a degree of acetalization of 65-85 mol% by using a 4C or lower aldehyde; 1-200 ppm of acetaldehyde (E1) based on the total of (A) and (B); and 1-200 ppm of butylaldehyde (E2) based on the total of (A) and (B). <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
