STABILIZATION OF PIGMENTED FIBERS WITH A SYNERGISTIC MIXTURE OF UV ABSORBER AND HIDDEN AMINE

摘要

Pigmented thermoplastic fiber, especially pigmented polypropylene fiber, are stabilized against the deleterious effects of actinic radiation by a synergistic combination of a hindered amine light stabilizer plus a UV absorber such as an o-hydroxyphenylbenzotriazole or an o-hydroxyphenyl-s-triazine.
