发明名称 OXOPIPERAZINYL DERIVATIVES AND LIGHT STABILIZED COMPOSITIONS
摘要 Compounds of the formula (I) <IMG> wherein p is zero or 1; q and r, independently of each other, are an integer from 1 to 6; and s is a number ranging from 1 to 8; X is -O- or, when p is 1, X is also a group <IMG>; Rw, Rx, Ry and Rz are, independently of each other, C1-C18alkyl, C5C12cycloalkyl or C1-C5hydroxyalkyl, especially methyl; R1 is hydrogen; C1-C18alkyl; oxyl; OH; CH2CN; C1-C18alkoxy; C5-C12cycloalkoxy; C3-C8alkenyl; C3-C8alkynyl; C7-C12phenylalkyl; C7-C15phenylalkyl, which is substituted on the phenyl ring by 1, 2 or 3 radicals selected from C1-C4alkyl and C1-C4alkoxy; C7-C15phenylalkoxy; C7-C15phenylalkoxy, which is substituted on the phenyl ring by 1, 2 or 3 radicals selected from C1-C4alkyl and C1-C4alkoxy; or R1 is C1-C8alkanoyl; C3C5alkenoyl; C1-C18alkanoyloxy; glycidyl; or a group -CH2CH(OH)-G, in which G is hydrogen, methyl or phenyl; R2 is hydrogen, C1-C8alkyl, C5-C12cycloalkyl or C1-C4hydroxyalkyl; R3, R4, R5 independently of each other are hydrogen, C1-C8alkyl or C5C12cycloalkyl; and W and other residues are as described in claim 1, are effective stabilizers for organic materials, for example thermoplastic organic polymers, coating compositions or photographic materials.
