Abstract: Disclosed are aminomethylenecyanoacetic acid esters and amides of formula (I), in which R and R , independently of each other, are phenyl, naphthyl, biphenyl or a five- or six-membered hetero-aryl group which has one, two or three nitrogen atoms or one oxygen atom or one sulphur atom or one nitrogen and one oxygen atom or one nitrogen and one sulphur atom, and which may be benzannulated, whereby these groups may be substituted by one to three C1-C12-alkyl groups, C1-C12-alkoxy groups, halogen atoms, cyano groups, hydroxy groups or groups of the formulae COOR COR , CONHR , OCOR or NHCOR , where R is C1-C12-alkyl, C5-C8-cycloalkyl or phenyl; X is a C2-C30-alkylene group which may contain non-adjacent oxygen atoms, a C4-C12-alkylene or C4-C12-alkinylene group (the unsaturated bonds not being adjacent to the ester oxygen atoms), a C5-C8-cycloalkylene group or a phenylene group; and Y is O or NH. These compounds can be used as stabilizers for organic materials.
