FIELD: polymer materials. SUBSTANCE: finer, particularly pigmented polypropylene fiber stabilized against damaging effect of actinic rays by synergistic combination of light stabilizer (spatially hindered amine) and UF adsorbent such as o-hydroxyphenylbenzotriazole, o-hydroxyphenyl-S- triazine, or 2-hydroxy-4-octyloxybenzophenone. EFFECT: increased antidegradation stabilization. 12 cl, 30 ex
