An hydroxyalkyl- and alkoxyalkyl-triazolidine-3,5-dione is disclosed of the formula (I) wherein R1 represents an unsubstituted or substituted aliphatic radical, which is straight-chain or branched, with 1-20 C atoms, mono- or poly-cycloaliphatic radical with 5 to 21 C atoms, araliphatic radical with 7 to 17 C atoms or aromatic radical with 6 to 20 C atoms, each radical carrying m of the radicals shown in brackets, and it being possible for the aliphatic radicals to be interrupted by one or more oxygen atoms or tertiary nitrogen atoms and for the cycloaliphatic, araliphatic and aromatic radicals to be interrupted by one or more oxygen atoms, tertiary nitrogen atoms or methylene groups with 1 to 4 C atoms, R2 and R3 independently of one another denote hydrogen or a straight-chain or branched aliphatic radical with 1 to 10 C atoms, R4 represents hydrogen or an aliphatic radical, which is straight-chain or branched, with 1 to 20 C atoms, mono- or poly-cycloaliphatic radical with 5 to 10 C atoms or araliphatic radical with 7 to 17 C atoms and m denotes an integer from 1 to 5, and wherein, in the case where m=1, R1 can also represent the radical a process for the preparation of such compounds by reaction of a triazolidine-3,5-dione with an aliphatic aldehyde or ketone, optionally simultaneously with or followed by reaction of the resultant hydroxyalkyl triazolidine-3,5-diones with an alcohol.
