  • Acrylic resin film and laminated film comprising the same
    Patent number: 6649104
    Abstract: An acrylic resin film made from a composition having 95 to 50 wt. parts of an acrylic resin having a glass transition temperature of 60 to 110° C. and a weight average molecular weight of 70,000 to 600,000, and 5 to 50 wt. parts of a multilayer-structured acrylic polymer containing an elastomeric layer, and a multilayer film having the above acrylic resin film and other resin film. These films have better thickness accuracy, surface smoothness and surface hardness than conventional acrylic resin films, with excellent properties as films for use in simultaneous injection molding and lamination, agricultural films, display films, masking films, paint-substitute films, and the like.
