Abstract
The present invention provides an acrylic resin laminated film comprising a soft layer formed of an acrylic resin incorporated with rubber particles and having a flexural modulus of about 1,300 MPa or less, and a hard layer formed of an acrylic resin having a flexural modulus of about 1,800 MPa or more on at least one side of the soft layer, wherein the hard layer has a thickness of about 0.1 to about 30 &mgr;m and a ratio of the thickness of the hard layer to the overall thickness of the laminated film is about 50% or less. This acrylic resin laminated film has moderate surface hardness and flexibility and hence is capable of providing for a molding with less whitening when subjected to a molding or forming process including bending or stretching.
