Abstract
Abstract Monocarboxamides of formula I ##STR1## wherein R is a radical of formula ##STR2## C 9 -C 19 alkyl, C 9 -C 19 alkenyl or C 9 -C 19 alkdienyl, wherein each R 2 independently of the other is a hydrogen atom or C 1 -C 4 alkyl, each R 3 independently of one another is a hydrogen atom or a hydroxyl group and at least one R 3 is a hydroxyl group, and R 1 is a radical of formula ##STR3## are suitable for curing epoxy resins, in ##STR4## are suitable for curing epoxy resins, in particular for cold curing.
