Abstract

Process for stabilizing organic material, characterized in that the said material is combined with a compound of the general formula i ** (see formula) ** Or its acid salts Wherein r represents hydrogen, a straight or branched chain alkyl radical, having from 1 to 20 carbon atoms, wherein the alkyl chain may be uninterrupted or interrupted by one or more sulfur atoms, a cycloalkyl radical having from 5 to 12 carbon atoms, a cycloalkyl radical having from 6 to 12 carbon atoms, a phenyl radical, an arylalkyl radical containing from 7 to 14 carbon atoms or an alkylaryl radical having from 7 to 12 carbon atoms. To 14 carbon atoms or r represents the grouping of the formula ** (see formula) ** Wherein y is a bivalent alkylene radical, straight or branched chain, having 1 to 20 carbon atoms, wherein the alkylene chain is uninterrupted or interrupted by one or more sulfur atoms, or a radical of arylene having 6 to 12 carbon atoms is either 0 or 1, or r represents the group having the formula: ** (see formula) ** Derived from the reaction between an acid hydrazide of the formula R conh.nh2 (IV) Or an acid dihydrazide of the formula ** (see formula) ** Where r, y and a have the same meaning as already stated, with triacetonamide of the formula ** (see formula) ** By heating said reactants in a solvent inert to them, preferably aliphatic alcohol, ether or aromatic hydrocarbons; Whose compound of formula i, resulting from the reaction, is combined with the organic material in a proportion of 0.01 to 5% by weight, and preferably 0.1 to 2% by weight, relative to the untreated organic material, in the presence of of an antioxidant, a stabilizer to the subsequent light, a complete metal deactivator, a pigment, an anti-slip or anti-static agent, a filler, a dye or crystal or other fibers.
