ABSTRACT:
This invention relates to an ink jet ink composition comprising an aqueous medium and microgel particles, said particles comprising a crosslinked copolymer prepared from a monomer mixture comprising at least a crosslinking monomer, a polymerizable carboxylic acid monomer, and one or more polymerizable water insoluble vinyl type monomers. The ink composition may be a colorless ink or it may contain a colorant.
