A-18184/A ortho-Hydroxyphenylacetamides Abstract of the disclosure: Compositions comprising an organic material which is subject to thermal, oxidative and/or actinic degradation and at least one compound of the formula I Image (I) are described, in which R is hydrogen, C1-24alkyl, C5-12cycloalkyl, phenyl, phenyl-C1-4alkyl or a radical of the formula II, Y is -CHR5-, sulfur or a direct bond, R1 is hydrogen, C1-4alkyl, phenyl or nitro-, chlorine-, fluorine-, C1-8alkyl- or/and methoxy-substituted phenyl, R5 is hydrogen, C1-8alkyl or phenyl, R2 and R3, independently of one another, are hydrogen, C1-20alkyl, C5-12cycloalkyl, benzyl, phenyl, C1-18alkyl-substituted phenyl, C2-4hydroxyalkyl, naphthyl, radicals of the formulae Image or together with the N atom to which they are bound are a 5-7-membered heterocyclic ring, or R2 is -NHR14 and R3 is as defined above, R14 is hydrogen, C1-12alkyl, phenyl or C1-4alkyl-substituted phenyl, R15 is hydrogen, C1-4alkyl or phenyl and d is an integer from 1-18, R6 is hydrogen or C1-20alkyl and x is an integer from 1 to 5, R7 is hydrogen, C1-8alkyl, C1-12alkoxy or CO-R9, R9 is phenyl or C1-8alkyl, or, if R3 is hydrogen and R is not a group of the formula II, R2 is also a radical -D-E, in which -D- has the formula Image , Image , -CyH2y-NH-, Image - or Image and -E has the formula IIa Image or IIb and the radicals E are bound to the NH groups of the radicals -D-, b is an integer from 0 to 2 and y is an integer from 0 to 12, R8 is hydrogen, C1-12alkyl or C5-12cycloalkyl, R10 is C1-24alkyl or phenyl, R4 is hydrogen, C1-20alkyl, C5-12cycloalkyl, benzyl, phenyl, C1-4alkyl-substituted phenyl, C1-4alkoxy, -CnH2nCO2R11 or III, R11 is hydrogen, C1-18alkyl, -CzH2z-A or -CH2-C(CH2A)3, A is IIIa and z is an integer from 2 to 12, n adopts the value 0, 1 or 2, R12 and R13, independently of one another, are hydrogen, C1-8alkyl, phenyl or C5-12cycloalkyl, or, if R12 is methyl, R13 is also Image or Image , L is a radical of the formula IIIb, p is 1 or 2 and q is an integer from 2 to 12, with the proviso that R is a radical of the formula II only if R4 is not a group of the formula III and the molecule does not contain a radical of the formula IIIa. Subformulae II, IIa, IIb, III, IIIa and IIIb are as defined in patent claim 1. The compounds of the formula I are suitable in particular for stabilising lubricants, metal-working fluids and hydraulic fluids and thermoplastics and elastomers.
