Abstract

Inks used for resistive ribbon thermal transfer contain a low-melt interlayer between the ink layer and substrate. The interlayer facilitates transfer and lift-off (correction) at low current levels. Unfortunately, the interlayer, which is an adhesive, adheres to the glass exposure plate of copying machines. Hence, automatic or semiautomatic document feed mechanisms fail to operate. The problem is solved by incorporating ,in the interlayer, particles which are at least equal in diameter to the thickness of the interlayer and which protrude from the interlayer. Upon printing, the particles, organic or inorganic, or mixtures of both, protrude from the interlayer and form points or extrusions which, in the copying machine, touch the surface of the exposure plate.
