ABSTRACT:
An aqueous ink composition of an oil-soluble dye in a latex is disclosed. The oil-soluble dye is dispersed in a fortified latex comprising a blend of a distinct dispersed phase in a distinct soluble polymer phase. The soluble polymer generally has a weight-average molecular weight of about 5,000 to about 20,000 and an acid number of about 50 to 400. These novel ink compositions have been found to be especially useful in gravure and flexographic ink applications.
