<p>PURPOSE:To provide a solidified ink which is used for marking pen, felt pen, ball point pen, etc. and makes it possible to write without the use of pen tip, prepared by adding a solidifying agent to ink. CONSTITUTION:Ink is solidified by adding poly-gamma-benzyl-L-glutamate, sodium stearate, sodium myristate, etc. as solidifier, to water-based ink or by adding isopropyl myristate, anisol-p-aminoazotoluene, etc. as solidifier, to oil ink. The solidifying agent is added in an amount of about 5-10wt% (about 1-4wt% will suffice when ink is solidified directly within writing utensils).</p> |
