Erasable ink for porous tip writing instruments |
| abstract |
Disclosed herein is a water-based erasable ink for use in a writing instrument. The ink comprises platy-like pigment particles, film formers and an aqueous vehicle. Also disclosed are writing instruments using such inks as well as comprising a reservoir containing a water based erasable ink having a non-shear-thinning composition and a porous fiber nib in fluid communication with this reservoir. Related methods of forming an erasable marking are also disclosed. |
