    Abstract: A b s t r a c t A highly-reactive powder resin composition suitable for use in the production of coatings comprising a mixture of A) at least one polymer containing groups selected from hydroxyl and epoxy-groups, having a melt viscosity of 2 000 to 20 000 cP at 160.degree.C and a melting range of from 45 to 95.degree.C; and B) at least one compound of formula (I) (cf. formula sheet) wherein R represents a radical selected from the group consisting of a) an unsubstituted mono- to pentavalent aliphatic hydrocarbon group containing from 1 to 28 carbon atoms, b) a radical a) being substituted by one of the groups an ester group containing from 1 to 6 carbon atoms and a carboxy group, c) a radical a) being interrupted at least once by one of the linkages an O-ether linkage and a -HC-CH- group, d) a piperazine group, e) a group of one of the formulae (XVI) and (XVII) an aromatic group containing from 6 to 43 carbon atoms of one of the formulae (X) to (XV) (cf. formula sheet) wherein R3 is a member selected from the group consisting of hydrogen, a halogen atom, an alkyl and an alkoxy group each containing from 1 to 6 carbon atoms and X represents a member selected from the group consisting of an oxygen atom, sulphinyl, sulphonly carbonyl and a group of the formulae (XVa) (cf. formula sheet) in which n has the value 1 to 8, R1 represents a radical selected from the group consisting of phenyl, naphthyl, phenanthryl, aminomaphthyl and a heterocyclic tetrahydrofuryl group such that the anhydride grouping is attached to the said R1 group on vicinyl carbon atoms; and y is an integer from 2 to 4 said comoment B having a melt viscosity of 50 to 15 000 cP at 160.degree.C and amelting range of from 40 to 250.degree.C; the combination of A and B having a melt viscosity of from 500 to 20 000 cP at 160.degree.C, a stability of from 1 to 15 at 100.degree.C, a flow time of from 20 to 600 s at 160.degree.C, and a gel time of from 35 to 1,200 s at 160.degree.C and an article coated with said composition.

    Abstract: A process for the preparation of modified N,N'-substituted-2,4,5-triketoimidazolidines which comprises reacting a precondensate having terminal isocyanate groups, prepared by reacting (a) a polybasic carboxylic acid, containing from 4 to 70 carbon atoms and from 2 to 6 carboxyl groups, with an excess of (b) one or more isocyanates or isocyanate forming compounds in the presence of a solvent, with (c) at least one oxamidic ester containing the group NH-CO-CO-ORv wherein Rv represents an aliphatic hydrocarbon group containing up to 18 carbon atoms, a cycloaliphatic hydrocarbon group containing up to 8 carbon atoms or a mononuclear aromatic hydrocarbon group being unsubstituted or substituted by at least one hydrocarbon group and having a total of up to 14 carbon atoms in the presence of a solvent, a product prepared by said process and a shaped article comprising such a product.
