<p>Pressure-sensitive reusable transfer elements of the squeeze-out type having a microporous resinous ink-releasing layer firmly bonded to a flexible foundation. The invention is characterized by the use of a bonding layer which is applied to the foundation as an aqueous composition comprising a mixture of two water-dispersible resinous binder materials, one of which is water-soluble and does not insolubilize on drying and the other of which is insoluble in water in that it forms a water-insoluble film on drying.</p> |
