| titleOfInvention | Bleed resistance of dyes by counter-ion substitution |
| abstract | Color bleed on paper media printed by ink-jet is alleviated by altering the dyes such that they become more bleed resistant. To this end, an organic compound with surfactant properties is substituted as the dye counter-ion. Specifically, a dye having one or more sulfonate or carboxylate groups is provided with a counter-ion comprising an amine having the formula given by n n ⁺N-(CH₃) m H 3-m -(CH₂) n -R n n n where m ranges from 1 to 3, n ranges from 3 to 6, and R a hydrophilic substituent or cycloaliphatic or aromatic group with a hydrophilic substituent. An ink employing the dye of the invention comprises (a) about 0.5 to 40 wt% of one or more low vapor pressure solvents (b) about 0.5 to 5 wt% one or more water-soluble dyes in which one or more of the counter-ions have been substituted with the above amine, and (c) the balance water. |
