Beschreibung
Zusammenfassung:	A film comprising a) at least one base layer comprising a thermoplastic polymeric matrix material; and b) a skin layer comprising a thermoplastic polymeric matrix material and from 5 wt % to 80 wt % of polymeric particles having an average particle diameter from 0.5 μm to 15 μm, a refractive index from 1.46 to 1.7, and at least 60 mole % of acrylic monomer units wherein the film is stretched by a factor of 2 to 8 uniaxially or biaxially; and wherein after stretching, the skin layer has a thickness that is between 50% and 200% of the diameter of the polymeric particles, and a method of making the film, are disclosed.
