ABSTRACT:
A radiation-curable ink jet ink can be formulated with less than 20% by weight of monofunctional monomer by dispersing the pigment or pigments with an acrylated epoxy resin having an average of from about 1.6 to about 2.0 functional groups per molecule, a number average molecular weight of from about 350 to about 600, and a glass transition temperature of from about −20° C. to about +25° C.
