PRINTING INK HAVING ENHANCED GLOSS AND LOWER VISCOSITY |
摘要 |
This disclosure relates to ink composition, having a viscosity of 0.02-13 Poise, comprising an inorganic pigment surface treated with alumina and at least one silicon based surface treatment selected from the group consisting of polysiloxane and polysiloxane block polymer to form a treated inorganic pigment, wherein the silicon based surface treatment is present in the amount of about 0.3 to about 1%, based on the total weight of the treated inorganic pigment; a binder resin having a glass transition temperature of less than 50° C., and comprising at least one adhesion promoting group; and a solvent based ink vehicle having the following solubility parameters using the MPa1/2 units: &sgr;d of greater than about 15.9, a &sgr;p of less than about 9.1 and a &sgr;h of less than about 12.1. These inks have enhanced gloss and lower viscosity characteristics. |
