A color concentrate, the color concentrate comprising a dye and an ionomer.
A hot melt ink concentrate, the ink concentrate comprising a colorant, a non-wax colorant blend agent, and a resin, the resin having a composition that is different from the composition of the colorant blend agent.
A color concentrate, the color concentrate comprising a colorant and a colorant blend agent, the colorant comprising a dye, the colorant blend agent comprising a metal, and the color concentrate combinable with a base component to make an ink composition with a dye concentration greater than about 10 weight percent.
An ink composition, the ink composition comprising:
- a wax;
- and
- a dye, the weight percent of the dye in the ink composition being greater than about 15%.
An ink composition, the ink composition comprising:
- an ionomer;
- a vehicle;
- and
- a colorant, with the ink composition being black in color and with the L* value of a substantially uniform thin film of the ink composition being not more than about 12.
An ink composition, the ink composition comprising:
- an ionomer;
- a vehicle;
- and
- a colorant, with the ink composition being magenta in color and with the C*.sub.ab value of a substantially uniform thin film of the ink composition being greater than about 45.
An ink composition for ink jet recording on a recording medium at temperatures higher than room temperature, the ink composition comprising:
- a vehicle comprising a mixture of at least a wax and a resin;
- an effective amount of a colorant combined with the vehicle to provide sufficient optical density for recording;
- and
- an effective amount of a blend agent to allow the colorant to either dissolve or disperse in the vehicle and provide a stable ink composition.
A hot melt composition, the hot melt composition comprising:
- a color concentrate, the color concentrate comprising:
- a colorant, and
- a colorant blend agent, the colorant blend agent comprising a metal;
- and
- a base component.
An ink composition, the ink composition comprising:
- a color concentrate, the color concentrate comprising:
- a first component, and
- a colorant;
- a second component, the second component being less polar than the first component;
- and
- a blend agent, the blend agent being different from the first component and the blend agent effective to enhance color uniformity in the first and second components.
A colorant blend agent, the colorant blend agent usable in a composition comprising a color concentrate and a first component, the color concentrate comprising a colorant and a second component, the blend agent being different from the first component, the second component being more polar than the first component, and the colorant blend agent effective to enhance color uniformity in the first and second components.
A method of making a hot melt ink concentrate, the method comprising combining a colorant, a non-wax colorant blend agent, and a resin, the resin having a composition that is different from the composition of the colorant blend agent.
A method of making a color concentrate, the method comprising combining a dye and an ionomer.
