Patent

CA 2221473

A description is given of compounds of the formula I (see formula I) in which R1 is C1-C18alkyl; C5-C12cycloalkyl; C3-C6alkenyl; phenyl; C1-C18alkyl which is substituted by phenyl, OH, C1-C18alkoxy, C5-C12cycloalkoxy, C3-C18alkenyloxy, halogen, -COOH, -COOR4, -O-CO-R5, -O-CO-O-R6, -CO-NH2, -CO-NHR7, -CO--N(R7)(R8), CN, NH2, NHR7, -N(R7)(R8), -NH-CO-R5, phenoxy, C1-C18alkyl- substituted phenoxy, phenyl-C1-C4alkoxy, C6-C15bicycloalkoxy, C6-C15bicycloalkylalkoxy, C6-C15bicycloalkenylalkoxy, or C6-C15tricycloalkoxy; C5-C12cycloalkyl which is substituted by OH, C1-C4alkyl, C2-C6alkenyl or -O-CO-R5; glycidyl; -CO-R9 or -SO2-R10; or R1 is C3-C50alkyl which is interrupted by one or more oxygen atoms and/or substituted by OH, phenoxy or C1-C18alkylphenoxy; or R1 denotes the specific polymerizable radicals indicated in claim 1; R2 is C6-C18alkyl; C2-C6alkenyl; phenyl; C7-C11phenylalkyl; COOR4; CN; NH-CO-R5; halogen; trifluoromethyl; -O-R3; R3 embraces the definitions given for R1; the radicals R11 independently of one another are H; C1-C18alkyl; C3- C6alkenyl; phenyl; C7-C11phenylalkyl; halogen or C1-C18alkoxy, and the remaining radicals embrace the definitions given in claim 1, at least one of the radicals R1, R2 and R11 containing 4 or more carbon atoms. The novel compounds are effective as stabilizers for organic material against the damaging effect of light, oxygen and heat; they are also suitable for use in skin or hair protection preparations.
