Ultraviolet-absorbing stabilizers of the formula E-(G-R)n, L-(G-E)m, or [G-E1-G-Q]p where E is a radical derived from an oxanilide, benzalmalonate, alpha -cyanocinnamate or o-hydroxyphenylbenzotriazole, E1 is a radical derived from an oxanilide, G is -OCH2CHOH-, R is alkyl, phenyl or -CH2OT where T is alkyl or alkenyl, n is 1 or 2, m is 2 or 3, L is a direct bond, alkylene or other bis or tris radical, Q has the same meaning as L when m is 2, and p is 1 to 4, are particularly resistant to loss during weathering of outdoor thermoset or thermoplastic coating systems while exhibiting good stabilization efficacy and compatibility in said systems.
