Abstract
A dye-based fingerprint ink formulation includes a fatty-acid based dye dispersion including a fatty-acid based dye dispersed in a chemical composition having approximately equal first formulation parts of (a) 2 phenoxyethanol, (b) propylene glycol and (c) oleic acid and approximately equal second formulation parts of (d) sorbitan monopalmitate and (e) myristic acid, the second formulation parts being approximately one-half the amount of the first formulation parts, with the fatty-acid based dye being less than approximately one percent (1%), by weight, of the fatty-acid based dye dispersion.
