Abstract
Disclosed herein is a novel hot melt ink comprising a colorant ink and an ink vehicle wherein the ink vehicle comprises at least one polyhedral silsesquioxane compound present in a proportion of about 0.1 to 30 wt % based on the total weight of the hot melt ink composition.
Claims8
A hot melt ink composition comprising in combination:
- (a) a polyhedral silsesquioxane compound present in a proportion of about 0.1 to 30 wt % based on the total weight of the hot melt ink composition
- (b) an ink colorant;
- (c) a resin;
- (d) a tackifier;
- (e) a viscosity modifier.
A hot melt ink comprising a colorant ink and an ink vehicle wherein the ink vehicle comprises:
- at least one polyhedral silsesquioxane compound present in a proportion of about 0.1 to 30 wt % based on the total weight of the hot melt ink composition, and
- molecular, oligomeric or polymeric materials containing reactive moieties allowing polymerization of the materials through cross-linking reactions made to occur after said hot melt ink is jetted onto a substrate, the polymerization being achieved by subjecting the jetted inks to an oxidation treatment by contacting the jetted inks with a suitable oxidizing agent.
An ink vehicle for use in a hot melt ink composition containing an ink vehicle and an ink colorant, the ink vehicle consisting essentially of a polyhedral silsesquioxane compound present in a proportion of about 0.1 to 30 wt % based on the total weight of the hot melt ink composition.
