ABSTRACT:
An ink jet printing ink is first formulated in concentrated form, and in this form it is subjected to stressful operating conditions such as an elevated temperature. This stress causes particle formation. After filtration to remove these particles, the final ink formulation is prepared, including for the first time ingredients which inhibit particle formation.
