Abstract
This invention relates to inks, ink emulsions, and to transfer elements as well as their methods of manufacture. The transfer elements provided by the invention are useful in providing imprints, including infra-red scannable imprints which are sharp, well defined prints with no feathering and which have fast dry and have excellent smudge resistance. The transfer elements comprise a substantially non-absorbent base having a coating comprising a continuous phase containing, as a discontinuous phase, a colorant carried by a vehicle comprising at least one C.sub.12 to C.sub.20 alcohol, said vehicle having a melting point below about 20.degree. C.
Claims11
An oil-in-water emulsion, useful in preparing an image forming transfer element, comprising:
- a. a continuous aqueous phase comprising a solubilized partially hydrolyzed polyvinyl acetate polymer, hydrolyzed to the extent of between about 80% and about 95%, having dispersed therein
- b. a discontinuous dispersed phase comprising:
- i. at least about 40% by weight of a vehicle comprising at least one C.sub.12 to C.sub.20 aliphatic alcohol containing an even number of carbon atoms, said vehicle having a freezing point below about 20.degree. C., having dispersed therein
- ii. a colorant, which is a dye, a pigment, or a combination thereof, the ratio of polymer to the discontinuous phase (b) being between about 1:1 and 1:3.
