Abstract
The present invention provides a method for printing energy curable ink and coating compositions that comprise high amounts of multifunctional monomers, achieving cured inks and coatings that exhibit good adhesion to plastic substrates, good resistance when cured, and low amounts of uncured, migratable monomers. The method of the present invention employs electron beam curing of the ink and coating compositions, at accelerating voltages greater than or equal to 70 keV, and electron beam doses greater than or equal to 30 kGy, and preferably greater than or equal to 40 kGy.
