Abstract:
1. An addition compound prepared by: (A) reacting wherein wherein, thr at least 75 mol % of the compounds of the formula (I), n is 1; with the proviso that the free isocyanate groups of component a) but not the uretdione groups are reacted with the compound(s) of the formula (I) to form an intermediate which contains the uretdione groups; and, (B-1) subsequently reacting the uretdione groups of the intermediate with wherein the amino groups in the polyamines and/or polyimines are reacted with epoxy-functional compounds, carbonates, carboxylic acids, carboxylic anhydrides and/or α,β-unsaturated compounds before the addition reaction with the uretdione; such that the products which are obtained following the reaction of the polyamines and/or polyimines with epoxy-functional compounds, carbonates, carboxylic acids, carboxylic anhydrides and/or α,β-unsaturated compounds contain reactive amino groups; or (B-2) subsequently reacting the uretdione groups of the intermediate with one or more polyamines and/or polyimines selected from the group consisting of diethylenetriamine, triethylenetetramine, tetraethylenepentamine, pentaethylenehexamine, hexaethyleneheptamine, polyamines of the general formula NH such that the products which are obtained following the addition reaction of the polyamines and/or polyimines with the uretdione contain reactive amino groups; and subsequently reacting amino groups remaining from the addition product of the polyamines and/or polyimines with the uretdiones with epoxy-functional compounds, carbonates, carboxylic acids, carboxylic anhydrides and/or α,β-unsaturated compounds.
