PRESSURE-SENSITIVE TRANSFER ELEMENTS AND METHOD Abstract of the Disclosure Method for producing novel multiple use pressure-sensitive transfer elements in the absence of volatile coating vehicles. The invention comprises preparing a molten coating composition including a compatible binder material mixture of hard wax and meltable synthetic resin, and a fluid ink comprising a solution of synthetic in an oleaginous vehicle which is substantially incompatible with said wax and substantially compatible with said synthetic resin, coating said mixture onto a thin flexible foundation such as a plastic film and cooling to form a solidi- fied cohesive microporous network of said binder material having uniformly dispersed within the pores thereof said fluid ink. Said ink is pressure-transferable from said network incrementally under the effects of imaging pressure along with that surface portion of the binder material network which is pressure-adhered to the copy sheet under the effects of the imaging pressure.
