ABSTRACT A heat-curable adhesive lacquer is provided which comprises: (a) a polyurethane-ester-imide having (i) terminal isocyanate groups blocked by a monohydric phenol, and (ii) free hydroxyl groups and (b) an essentially linear epoxide or polyester resin having secondary hydroxyl groups and a molecular weight of above 30,000, the lacquer achieving, on drying, a B-state which is stable on storage such that the lacquer softens again when further heat is supplied to give a cross-linked resin in the C-state, which is heat stable.
