Abstract
Abstract The present invention provides an adhesive composition comprising a polyurethane resin and, as adhesion promoter, a compound of formula I: ##STR1## in which Z is an organic radical which is derived from an aliphatic aromatic or heterocyclic polyisocyanate containing m+n isocyanate groups; m is a value greater than or equal to 1; n is a value greater than or equal to 0; m+n is a value greater than or equal to 2; Y is 0 or S; X is 0, S or N--C 1 -C 4 alkyl; R 1 is C 1 -C 8 alkylene; R 2 is C 1 -C 4 alkyl or two groups R 2 together for m a C 1 -C 4 alkylene residue; R 3 is C 1 -C 4 alkyl or phenyl; and q is a value from 0 to 2.
