ABSTRACT:
A shear-thinning ink composition for use in ball point pens contains a substantially reduced amount of water. These low water-containing inks contain a polymeric material and exhibit superior "cap off" properties by remaining free-flowing after the cap has been off of the pen for at least seven days. The ink compositions of this invention comprise as little as 4 parts by weight of water if the ink utilizes dye as the colorant and as little as 10 parts by weight of water, based on 100 parts of the total composition, if the ink utilizes pigment as the colorant.
