Non-exuding optically brightened polyolefin blends |
| abstract |
Optical brighteners are widely used for decreasing the apparent yellowness of polymeric materials. Polyethylene, as a coating film for photographic paper has presented unique problems because of its general lack of compatibility with conventional, large, fluorescent brightener molecules. The present invention provides a solution to this problem by incorporating into the polyethylene an optical brightener compatibilizing amount of a second polyolefin having alkyl groups pendant from the polymer backbone which serves to reduce the exudation of the optical brightener in articles or substrates comprised of or coated with such compositions. |
