ABSTRACT:
Compositions are provided comprising a film-forming crystalline polypropylene, crystalline block copolymer of propylene and at least one other .alpha.-monoolefin selected from the group of ethylene and .alpha.-monoolefin hydrocarbons of 4 to 10 carbon atoms or mixtures of the block copolymer and the polypropylene, having incorporated therein about 15 to 40% by weight talc, 5 to 15% by weight titanium dioxide pigment, 5 to 20% of an elastomer and one-tenth to 1% by weight of a polyolefin antioxidant.
The films or sheets prepared from these polyolefin compositions have the stiffness, opacity and printability normally associated with paper and provide excellent replacements for paper used in photographic elements. In addition, they have excellent tear strength and elongation.
