Image transfer on a colored base
An image transfer article can include an image-imparting member and a removable substrate disposed adjacent to the image-imparting member. The image-imparting member can have a softening point temperature less than about 220° C. The image-imparting member can include at least one surface configured to receive and carry indicia to be transferred and at least one portion comprising a pigment providing an opaque background for received indicia. In some examples, the image-imparting member can comprise a first polymer including the indicia and at least a second polymer including the pigment. In some examples, the image-imparting member can comprise a polymer including the indicia and the pigment. The indicia and the opaque background can be arranged to concurrently transfer to a woven- or fabric-based article or paper in contact with the image-imparting member, upon application of iron pressing temperatures.
1. An image transfer article comprising:
a release layer comprising at least one of a fluorocarbon, urethane, or acrylic base polymer;
an ink-receiving layer for receiving an ink or toner based image; and
a white layer positioned between the release layer and the ink-receiving layer and comprising a pigment to provide a pigmented background above which the ink or toner based image is received.
2. The image transfer article of claim 1 , further comprising a removable substrate on an opposite side of the release layer from the white layer and releasable from the release layer.
3. The image transfer article of claim 2 , wherein the white layer is configured to impart a white background for the ink or toner based image when transferred to a dark-colored substrate.
4. The image transfer article of claim 3 , wherein the pigment is titanium oxide.
5. The image transfer article of claim 3 , wherein, as the pigment, the white layer comprises a concentration of blended pigments of about 10% to 40% by weight of the white layer.
6. The image transfer article of claim 2 , wherein the ink-receiving layer comprises a polyamide.
7. The image transfer article of claim 6 , wherein the white layer has a melt index between 10 and 3500.
8. The image transfer article of claim 6 , wherein the white layer has a Vicat softening point of between about 40° C. to about 220° C.
9. The image transfer article of claim 6 , wherein the polyamide is insoluble in water.
10. The image transfer article of claim 2 , wherein the ink-receiving layer comprises a polyurethane.
11. The image transfer article of claim 2 , wherein the white layer has a thickness of between about 0.5 to 7 mils.
12. The image transfer article of claim 11 , wherein the white layer melts within the range of 40° C. to about 280° C.
13. The image transfer article of claim 12 , wherein the release layer, ink receiving layer, and white layer are concurrently transferable to an image-receiving article when they are, as a unit, placed in contact with the image-receiving article and heat is applied thereto.
14. The image transfer article of claim 13 , wherein the release layer comprises at least one of ethylene acrylic acid and ethylene vinyl acetate.
15. A method of making an image transfer article, the method comprising:
coating a release layer over at least a substrate layer, the release layer comprising at least one of a fluorocarbon, urethane, or acrylic base polymer;
coating a white layer over at least the release layer and substrate layer, the white layer comprising a white or luminescent pigment; and
coating an ink-receiving layer over at least the white layer, release layer, and substrate layer, the ink-receiving layer comprising a polyamide and configured for receiving an ink or toner based image;
wherein the white or luminescent pigment is provided in a sufficient concentration to provide a pigmented background for the ink or toner based image.
16. The method of claim 15 , wherein the white layer is formed by extrusion or co-extrusion emulsion coating or solvent coating.
17. The method of claim 15 , wherein the ink receiving layer is formed by roll coating, air knife coating, slot die coating, or a hot melt extrusion process.
18. The method of claim 15 , wherein the polyamide of the ink-receiving layer is emulsified in a solvent before coating.
19. The method of claim 15 , wherein the white layer is coated to a thickness of between about 0.5 to 7 mils.
20. The method of claim 19 , wherein the substrate is releasable from the release layer.
