ABSTRACT:
Novel semicarbazides of the formula ##STR1## wherein R.sub.1 and R.sub.2, each independently of the other, are hydrogen, C.sub.1 -C.sub.5 alkyl, C.sub.2 -C.sub.5 alkenyl, C.sub.1 -C.sub.5 alkoxy or phenyl, or R.sub.1 and R.sub.2, together with the linking nitrogen atom, form a morpholine or piperazine radical, p is 0 or 1, and Q depends on the value of p as described herein. The novel compounds, which are water-soluble in aqueous application systems, have fibre affinity and are suitable for the photochemical and thermal stabilization of polyamide fibre materials and the dyeings produced thereon.
