AMENDED CLAIMS
[received by the International Bureau on 24 March 2002 (24.03.02); original claims 1-41 amended; (6 pages)]
1. A pearlescent ink for use in a writing instrument, comprising: a shear-thinning additive, lubricious particles, and pearlescent pigment particles dispersed in a solvent.
2. The ink of claim 1 wherein said solvent comprises an aqueous solvent system.
3. The ink of claim 2 wherein the aqueous solvent system comprises at least one water-soluble organic solvent.
4. The ink of claim 2 wherein the aqueous solvent system comprises at least one water-soluble organic solvent selected from the group consisting of glycols, polyhydric alcohols, glycol ethers, glycol ether esters, amines, amides, and alkanolamides.
5. The ink of claim 1 wherein said ink has a shear-thinning index of between about 0.01 and about 0.8.
6. The ink of claim 1 , wherein the ink has a viscosity between 200 mPa-sec and 20,000 mPa-sec at a shear rate of about 1.0 sec"1, and a viscosity between 10 mPa-sec and 1000 mPa-sec at a shear rate of about 100 sec"1.
7. The ink of claim 1 wherein said ink has an erasability of at least about 80%.
8. The ink of claim 1 wherein said ink has a line intensity of at least about 25%.
50
9. The ink of claim 1 wherein said pearlescent pigment has an average particle diameter between about 2 microns and about 15 microns.
51
10. The ink of claim 1 further comprising a film-forming agent.
11. The ink of claim 1 further comprising a second pearlescent pigment.
12. The ink of claim 1 further comprising a non-pearlescent pigment.
13. The ink of claim 1 wherein said pearlescent pigment comprises a dichromatic pigment.
14. The ink of claim 1 wherein the shear-thinning additive is a clay, an organoclay, a water-dispersible gum, an acrylic acid-based polymer, or a combination thereof.
15. The ink of claim 1 wherein the pearlescent pigment is selected from the group consisting of natural pearl essence, bismuth oxychloride, and mica flakes coated with metal oxides.
16. The ink of claim 1 wherein the pearlescent pigment comprises mica flakes coated with a layer of metal oxide wherein the metal oxide layer is between about 40 nanometers and about 160 nanometers thick.
18. The ink of claim 1 wherein the lubricious particles comprise polymeric particles selected from the group consisting of polytetrafluoroethylene, polyethylene, polypropylene, polymethyhnethacrylate, nylon, modified polyethylene, modified polyamide, and various blends of these materials.
19. The ink of claim 1 wherein the lubricious particles have an average particle diameter between about 0.1 micron and about 30 microns.
31. The ink of claim 30 wherein the lubricious particles comprise polymeric particles selected from the group consisting of polytetrafluoroethylene, polyethylene, polypropylene, polymethylmethacrylate, nylon, modified polyethylene, modified polyamide, and various blends of these materials.
32. The ink of claim 30 wherein the lubricious particles have an average particle diameter between about 0.1 micron and about 30 microns.
33. A shear-thinning pearlescent ink, comprising: a pearlescent pigment; a solvent; and, a shear-thinning additive, wherein said pigment has an average particle diameter between about 1 micron and about 25 microns and is dispersed in said solvent, and the ink has a shear-thinning index of between about 0.01 and about 0.8.
34. A method of forming a marking on a substrate, comprising: making a marking on the substrate with a writing instrument containing a pearlescent ink comprising a shear-thinning additive, lubricious particles, and pearlescent pigment particles dispersed in a solvent.
35. A method of forming a marking on a substrate, comprising: making a marking on the substrate with a writing instrument containing a pearlescent ink comprising a dispersion of a pearlescent pigment in a solvent, the ink exhibiting an erasability of at least about 80%.
36. A method of forming a marking on a substrate, comprising: making a marking on the substrate with a writing instrument containing a pearlescent ink comprising a solvent, a shear-thinning additive, and a pearlescent pigment wherein said pigment has an average particle diameter between about 2 microns and about 15 microns and is dispersed in said solvent.
53
37. A method of forming a marking on a substrate, comprising:
54

39. A writing instrument, comprising: a reservoir containing a pearlescent ink comprising a dispersion of a pearlescent pigment in a solvent, the ink exhibiting an erasability of at least about 80%.
40. A writing instrument, comprising: a reservoir containing a pearlescent ink comprising a solvent, a shear- thinning additive, and a pearlescent pigment wherein said pigment has an average particle diameter between about 2 microns and about 15 microns and is dispersed in said solvent.
41. A writing instrument, comprising: a reservoir containing a pearlescent ink comprising a pearlescent pigment, a solvent, and, a shear-thinning additive, wherein said pigment has an average particle diameter between about 1 micron and about 25 microns and is dispersed in said solvent, and the ink has a shear-thinning index of between about 0.01 and about 0.8.
