DESCRIPTION:

BRIEF SUMMARY
This is the national stage application of PCT/EP 93/00739 filed Mar. 26, 1993.
The present invention relates to novel polyalkyl-piperidine-containing acetic acid and 3-aminoacrylic acid derivatives Ia ##STR2## where
R.sup.1 is hydrogen, C.sub.1 - to C.sub.6 -alkyl, formyl, C.sub.2 - to C.sub.6 -alkanoyl, C.sub.1 - to C.sub.12 -alkoxy, C.sub.5 - to C.sub.6 -cycloalkoxy, cyanomethyl, hydroxymethyl, 2-hydroxyethyl, or a radical of the formula --CR.sup.3 =CH--CO--OR.sup.4, where
R.sup.3 is hydrogen, C.sub.1 - to C.sub.5 -alkyl or a radical of the formula --CO--OR.sup.4 and
R.sup.4 is C.sub.1 - to C.sub.20 -alkyl, C.sub.5 - to C.sub.8 -cycloalkyl, C.sub.7 - to C.sub.18 -aralkyl, phenyl, tolyl or a radical of the formula --(CH.sub.2 CH.sub.2 O).sub.n H or --[CH(CH.sub.3)CH.sub.2 O].sub.n H, where n is a number from 1 to 30,
R.sup.2 is cyano
X is O, NH or NR.sup.6 where
R.sup.C.sub.1 - is C.sub.12 -alkyl, and
Y is hydrogen or a group of the formula =CH--NHR.sup.7 or =NH--NR.sup.6 R.sup. 7, where
R.sup.7 is phenyl which can be substituted by one to three C.sub.1 - to C.sub.12 -alkyl, C.sub.1 - to C.sub.12 -alkoxy, halogen, cyano, hydroxyl, phenyl or groups of the formula --CO--OR.sup.5, --CO--R.sup.5, --CO--NHR.sup.5, --O--CO--R.sup.5 or --NH--CO--R.sup.5, where R.sup.5 is C.sub.1 - to C.sub.12 -alkyl, C.sub.5 - to C.sub.8 -cycloalkyl, benzyl, phenyl or tolyl, is a 5- or 6-membered unsaturated or saturated heterocyclic ring having up to three hetero atoms from the group consisting of nitrogen, oxygen and sulfur, which can additionally be benzo-fused and substituted by one to three C.sub.1 - to C.sub.12 -alkyl, C.sub.1 - to C.sub.12 -alkoxy, halogen, cyano, hydroxyl, phenyl, phenoxy or C.sub.1 - to C.sub.12 -alkoxycarbonyl ##STR3##
Furthermore, the invention relates to organic material stabilized against the action of light, oxygen and heat in particular stabilized plastics and coatings, which contains from 0.01 to 5% by weight, based on the amount of the organic material, of one or more polyalkylpiperidine containing acetic acid and 3-aminoacrylic acid derivatives of the general formula I ##STR4## where
R.sup.1 is hydrogen, C.sub.1 - to C.sub.6 -alkyl, formyl, C.sub.2 - to C.sub.6 -alkanoyl, C.sub.1 - to C.sub.12 -alkoxy, C.sub.5 - to C.sub.6 -cycloalkoxy, cyanomethyl, hydroxymethyl, 2-hydroxyethyl or a radical of the formula --CR.sup.3 =CH--CO--OR.sup.4 where
R.sup.3 is hydrogen, C.sub.1 - to C.sub.6 -alkyl or a radical of the formula --CO--OR.sup.4 and
R.sup.4 is C.sub.1 - to C.sub.20 -alkyl, C.sub.5 - to C.sub.8 -cycloalkyl, C.sub.7 - to C.sub.18 -aralkyl, phenyl, tolyl or a radical of the formula --(CH.sub.2 CH.sub.2 O).sub.n H or --[CH(CH.sub.3)CH.sub.2 O].sub.n H, where n is a number from 1 to 30, R.sup.10 is cyano, a radical of the formula --CO--R.sup.5 or --CO--OR.sup.5 or a group of the formula ##STR5## where
R.sup.5 is C.sub.1 - to C.sub.12 -alkyl, C.sub.5 - to C.sub.8 -cycloalkyl, benzyl, phenyl or tolyl,
X is O, NH or NR.sup.6, where
R.sup.6 is C.sub.1 - to C.sub.12 -alkyl, and
Y is hydrogen or a group of the formula =CH-NHR.sup.7 or =CH--NHR.sup.7 or =CH--NR.sup.6 R.sup.7,
R.sup.7 is phenyl which can be substituted by one to three C.sub.1 - to C.sub.12 -alkyl, C.sub.1 -to C.sub.12 -alkoxy, halogen, cyano, hydroxyl, phenyl or groups of the formula --CO--OR.sup.5, --CO--R.sup.5, --CO--NHR.sup.5, --O--CO--R.sup.5 or --NH--CO--R.sup.5, is a 5- or 6-membered unsaturated or saturated heterocyclic ring having up to three hetero atoms from the group consisting of nitrogen, oxygen and sulfur, which can additionally be benzo-fused and substituted by one to three C.sub.1 - to C.sub.12 -alkyl, C.sub.1 - to C.sub.12 -alkoxy, halogen, cyano, hydroxyl, phenyl, phenoxy or C.sub.1 - to C.sub.12 -alkoxycarbonyl.
As is known, organic material, in particular plastics and coatings, is destroyed very rapidly, in particular by the action of light. This destruction usually manifests itself as yellowing, discoloration, crack formation or embrittlement of the material. Satisfactory protection against the destruction of organic
