Bicomponent reactive ink for ink jet printing

摘要

The present invention relates to (i) a reactive ink for ink jet printing comprising a two-component system, the first component comprising a polymerizable monomer, and the second component comprising a polymerization catalyst, wherein the monomer is able to form a polymeric film at low temperature within thirty minutes, preferably within ten minutes, from contacting the catalyst, (ii) a process of making an image on a non-porous substrate using such a reactive ink, and an ink jet print head including a two component ink-system.

主权项

1. A reactive ink for ink jet printing comprising:
an organic solvent as a carrier medium; and a two-component system,
the first component comprising a polymerizable monomer selected from the group consisting of aliphatic epoxy monomers, alicyclic epoxy monomers, aromatic epoxy monomers, and mixtures thereof, andthe second component comprising a polymerization catalyst selected from the group consisting of Lewis and Bronsted acids having a pKa equal to or lower than 4,wherein the polymerizable monomer is able to form a polymeric film at a temperature equal to or lower than 60° C. within thirty minutes from contacting the catalyst.
