Abstract
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 12 to C 20 alcohol, said vehicle having a melting point below about 20° C.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
114 words
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 12 to C 20 aliphatic alcohol containing an even number of carbon atoms, said vehicle having a freezing point below about 20° 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.
Claim 2
Dependent Claim
114 words
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 12 to C 20 aliphatic alcohol containing an even number of carbon atoms, said vehicle having a freezing point below about 20° 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.
Claim 3
Dependent Claim
16 words
An emulsion, as in claim 1, wherein the emulsion is essentially free of volatile organic solvent.
Claim 4
Dependent Claim
141 words
An oil-in-water emulsion, as in claim 1, useful in preparing an image forming transfer element comprising: 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 12 to C 20 aliphatic alcohol containing an even number of carbon atoms, said vehicle having a freezing point below about 20° C., having dispersed therein ii. a dye based colorant; combined with iii. a fatty acid, the amount of said fatty acid being a color developing amount less than the amount which combines with said dye base to form a non-separating combination, the ratio of polymer to the discontinuous phase (b) being between about 1:1 and 1:3.
Claim 5
Dependent Claim
13 words
An emulsion, as in claim 2, wherein the fatty acid is oleic acid.
Claim 6
Dependent Claim
16 words
An emulsion, as in claim 3, wherein the emulsion is essentially free of volatile organic solvent.
Claim 7
Dependent Claim
108 words
An oil-in-water emulsion, as in claim 3, consisting of a. a continuous aqueous phase comprising a solubilized partially hydrolyzed polyvinyl acetate polymer hydrolyzed to the extent of between about 80% to about 95%, b. a discontinuous dispersed phase comprising: i. at least about 40% by weight of oleyl alcohol, ii. a nigrosine base colorant, combined with iii. oleic acid, the amount of said oleic acid being a color developing amount less than the amount which forms a salt with all said nigrosine base, (a) and (b) being present in amounts to provide a ratio of (b) to the polymer in (a) of between about 1:1 to about 3:1.
Claim 8
Dependent Claim
17 words
An emulsion, as in claim 6, which contains a transfer rate decreasing amount of a weak base.
Claim 9
Dependent Claim
28 words
An emulsion, as in claim 1, which contains a minor transfer rate modifying amount of a resin selected from the group consisting of polyvinyl alcohol and polyvinyl acetate.
Claim 10
Dependent Claim
12 words
An emulsion, as in claim 6, wherein the base is ammonium hydroxide.
Claim 11
Dependent Claim
11 words
An emulsion, as in claim 1, which contains a particulate filler.
Claim 12
Dependent Claim
22 words
An emulsion, as in claim 1, which contains a particulate filler selected from the group consisting of starch and chemically modified starch.
