Acrylic resin containing film and a manufacturing method thereof

A transparent and high heat resistance, provides an acrylic resin containing film brittleness was significantly improved, and a manufacturing method thereof. Acrylic resin-containing film of the present invention is an acrylic resin containing film containing an acrylic resin as a main component, an acrylic resin and cellulose ester resin 95: 5-30: contain 70 weight ratio of the cellulose ester the total acyl substitution degree of the resin is from 2.00 to 2.99, an acetyl group substitution degree of 0.10 to 1.89, the number of carbon atoms of the acyl groups other than acetyl group is 3-7, the weight average molecular weight a 75,000 to 280,000, the tension softening point haze is less than 1% of said acrylic resin-containing film is 105 to 145 ° C., and is characterized by not cause ductile fracture.
