Abstract
A thermoplastic acrylic resin brittle film which has a tensile strength at break of 1.0 to 3.0 kg/mm,and an elongation at break of 2.0 to 20.0%, and is prepared from a resin composition which comprises (A) 100 parts by weight of a thermoplastic acrylic resin, (B) 10 to 70 parts by weight of a filler and, optionally, up to 30 parts by weight plasticizer. The filler can be (a) fused silica aggregates of particles having an average diameter of the particles in the range of 5 to 20 &mgr;m and diameters of the particles in the range of 0.5 to 100 &mgr;m, (b) aluminum hydroxide aggregates of particles having an average diameter of the particles in the range of 1 to 20 &mgr;m and diameters of the particles in the range of 0.2 to 50 &mgr;m, (c) barium sulfate aggregates of particles having an average diameter of the particles in the range of 1 to 20 &mgr;m and diameters of the particles in the range of 0.2 to 50 &mgr;m, and (d) calcium carbonate aggregates of particles having an average diameter of the particles in the range of 0.5 to 20 &mgr;m and diameters of the particles in the range of 0.1 to 50 &mgr;m.
