    Abstract: Method for producing novel reusable pressure-sensitive transfer elements by solvent-coating techniques in which a composition comprising resinous film-forming binder material, incompatible oil, coloring matter and an aqueous vehicle is coated onto a flexible foundation and dried by evaporation of the aqueous vehicle. Transfer elements which are curl-resistant and substantially free of undesirable surface ink migration or ''''sweating'''' result from the use of a mixture of certain amounts of water-dispersible resinous film-forming binder materials comprising from 40 to 80% by weight of a water-insoluble filmformer and from 60 to 20% by weight of a water-soluble filmformer.
