Abstract

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 water-dispersible, water-insoluble resinous binder material which dries to form a tacky, adhesive layer.
