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.
Claims19
An image producing transfer element comprising a non-absorbent treated paper, fabric or plastic film base having a coating comprising:
- a. a continuous phase comprising a partially hydrolyzed polyvinyl acetate polymer hydrolyzed to the extent of between about 80% and about 95%,
- b. a pressure expressible image forming discontinuous 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 having 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, and wherein the ratio of polymer to the discontinuous phase (b) is between about 1:1 and about 1:3.
A method of forming a transfer element which comprises coating a non-absorbent base material with an emulsion 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 and wherein the ratio of polymer to discontinuous phase (b) is between about 1:1 and about 1:3 and drying the resultant coated article.
A method of forming a transfer element which comprises
- a. forming an ink 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 dye base which has been reacted with a fatty acid, the amount of fatty acid present in the ink being a dye base color developing amount less than the amount which reacts with all of the dye base present,
- b. forming an emulsion of said ink in an aqueous solution comprising a partially hydrolyzed polyvinyl acetate polymer hydrolyzed to the extent of between about 80% and about 95%, the ratio of polymer to ink (a) being between about 1:1 and about 1:3,
- c. coating said emulsion upon a non-absorbent treated paper, fabric or plastic film base material,
- d. drying the resultant coated article.
