1. Claims (for the Contracting States : BE, CH, DE, GB, LI, NL) Use of Mannich-bases of the general formula see diagramm : EP0068263,P16,F1 as cross-linking agents for epoxy resins for the production of shaped articles, in which in formula (I) R**10 is hydrogen or the group see diagramm : EP0068263,P16,F2 in which R**1 to R**3 represent identical or different alkyl radicals having 1 to 5 carbon atoms each, it also being possible, however, for one of the radicals R**1 to R**3 to be hydrogen, and, in this case, for the other two radicals together to represent an alkylene radical of 4 to 6 carbon atoms, each of which can be substituted by a group such as -OH or -OR**5 , which is inert with respect to the formation of the Mannich-base and to the epoxide hardening reaction, R**4 denotes H-, HO-, HOOC- or alkyl radicals having 1 to 9 carbon atoms, R**5 denotes alkyl having 1 to 5 carbon atoms, R**6 is hydrogen or alkyl having 1 to 4 carbon atoms and R**7 is one of the following groups (II) to (XII) : see diagramm : EP0068263,P16,F3 see diagramm : EP0068263,P16,F4 see diagramm : EP0068263,P16,F5 see diagramm : EP0068263,P16,F6 see diagramm : EP0068263,P16,F7 see diagramm : EP0068263,P16,F8 see diagramm : EP0068263,P16,F9 see diagramm : EP0068263,P16,F10 see diagramm : EP0068263,P17,F1 see diagramm : EP0068263,P17,F2 and see diagramm : EP0068263,P17,F3 in which in formula (X) n is an integer from 2 to 6 and in formulae (IX) to (XII) m is an integer from 1 to 4 and in which R**8 is H- or CH3 - and wherein at most 50%, preferably at most 25% of the radicals R**8 are CH3 . 1. Claims (for the Contracting State : AT) Process for the production of shaped articles and coating by reaction of epoxide compounds having more than 1,2-epoxy groups per molecule, which optionally can be in mixture with monoepoxides, with substituted amines, as substituted amines Mannich-bases of the general formula see diagramm : EP0068263,P18,F1 being used, in which in formula (I) R**10 is hydrogen or the group see diagramm : EP0068263,P18,F2 in which R**1 to R**3 represent identical or different alkyl radicals having 1 to 5 carbon atoms each, it also being possible, however, for one of the radicals R**1 to R**3 to be hydrogen, and, in this case, for the other two radicals together to represent an alkylene radical of 4 to 6 carbon atoms, each of which can be substituted by a group such as -OH or -OR**5 , which is inert with respect to the formation, of the Mannich-base and to the epoxide hardening reaction, R**4 denotes H-, HO-, HOOC- or alkyl radicals having 1 to 9 carbon atoms, R**5 denotes alkyl having 1 to 5 carbon atoms, R**6 is hydrogen or alkyl having 1 to 4 carbon atoms and R**7 is one of the following groups (II) to (XII) : see diagramm : EP0068263,P18,F3 see diagramm : EP0068263,P18,F4 see diagramm : EP0068263,P18,F5 see diagramm : EP0068263,P18,F6 see diagramm : EP0068263,P18,F7 see diagramm : EP0068263,P18,F8 see diagramm : EP0068263,P18,F9 see diagramm : EP0068263,P18,F10 see diagramm : EP0068263,P19,F1 see diagramm : EP0068263,P19,F2 and see diagramm : EP0068263,P19,F3 in which in formula (X) n is an integer from 2 to 6 and in formulae (XI) to (XII) m is an integer from 1 to 4 and in which R**8 is H- or CH3 - and wherein at most 50%, preferably at most 25% of the radicals R**8 are CH3 .
