    摘要: 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 waterdispersible resinous binder materials, one of which is watersoluble 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.
