Process for coating metal articles with PVC or vinyl chloride copolymers takes place by (1) using plastisols contng. finely divided PVC or vinyl chloride copolymers, standard plasticisers, fillers and additives and, as adhesive agents, (A) Schiff bases contng. 0.1-0.4 (0.1-1) azomethine gps./100 g. cpd. and/or (B) enamines contng. 0.1-1.4 (0.1-1) enamine gps./100 g. cpd., alone or in mixtures, in quantities of 0.1-4 (0.3-2) wt.% w.r.t. PVC compsn. and (2) stoving the coatings at 120-200 degrees C. Uses include coating automobile body sheet iron. The claimed plastisols can be stoved at relatively low temps., e.g. 120-160 degrees C., to give coatings which have good adhesive strength, without colour-changes, structural defects and blisters.
