Abstract:
1. A polyol (A) based on modified amino resins, for use in a thermally curable composition, prepared by reacting: an amino resin (B) comprising three acetalized or etherified N-methylol groups of the general formula I: wherein R is a hydrogen atom, an alkyl group of 1 to 6 carbon atoms or an aryl group of 6 to 10 carbon atoms and R 1 is an alkyl group of 1 to 6 carbon atoms; with a polyol (C) of the general formula II: wherein n is 2 and R 2 is a divalent organic radical and wherein polyol (C) is selected from the group consisting of positionally isomeric diethyloctanes containing a linear C 8 carbon chain and functionalized with two hydroxy groups; wherein an equivalent ratio of the acetalized or etherified N-methylol groups to the polyol (C) is 0.5:1 to 1.2:1; with elimination of at least 50 mol % of a monoalcohol (D) of the general formula Ia: wherein R 1 is as defined above, from the amino resin (B), wherein the polyol (A) is capable of use in preparing a thermally curable coating material.
