The adhesive properties of vinyl resins are substantially improved by adding thereto or mixing therewith polyfunctional aziridines dissolved in inert organic liquid media. The polyfunctional aziridines may be added to vinyl resins which are in solution, to vinyl resins which are in the form of organosols or plastisols, or to vinyl resins which are in the form of solids (powders). The process of this invention has found particular utility in the coating of vinyl resins upon nonporous surfaces.
