Abstract
The present invention relates to compounds containing modified hydrazide groups and corresponding to formula I whereinR represents the residue obtained by removing the isocyanate groups from a monomeric polyisocyanate, a polyisocyanate adduct or an NCO prepolymer,X represents OR′ or NHR′ andR′ represents a group which is inert to isocyanate groups under the conditions used to form the compound of formula I,R″ represents a divalent, linear or branched aliphatic group containing 2 to 10 carbon atoms, provided that there are at least two carbons between the oxygen atoms wherein the aliphatic group may optionally be substituted by heteroatoms to form ether or ester groups, andn is 2 to 6.
