Process for the production of solutions of segmented self-crosslinkable polyurethanes by incorporating in the polymer chain segments of the general formula M-CO-NH-D'-NH-CO-A, wherein D' is the divalent residue of an organic diisocyanate; M is a diol containing residue derived by reaction of the active N-hydrogen of an aminodiol or a hydrazinodiol which contains a primary or secondary amino group, with an isocyanate group; and A is an isocyanate masking group. |
