INK SET AND METHOD FOR REDUCING BLOTTING ON PRINT |
摘要 |
Bleed between two adjacent inks on a printing medium may be reduced by selecting inks having the same ionic character, at least one ink containing an aqueous carrier medium and a pigment dispersion wherein the dispersant is a quaternized amine containing polymeric dispersant, and wherein the second ink contains an aqueous carrier medium, a colorant and optionally a polymer, wherein the colorant or the polymer has a sulfonate or phosphonate group. A process for alleviating bleed in printed elements comprising applying the first and second inks to a substrate in contact with each another is also described. |
