  • Publication number: 20080226833
    Abstract: Radiation curable ink compositions that include a curable component having a functionality that is greater than two, is present in the ink composition in an amount greater than 30 percent by weight, and has a molecular weight in the range of about 400 g/mole to about 10,000 g/mole; a component that has a functionality that is less than or equal to 2; and an initiator component. A solvent component, pigment, a surface tension modifier and other materials also can be included. The radiation curable inks are employed in ink jet printers and are particularly suited for use in printing on large-scale substrates. The printed images described herein have good adhesion to polymeric substrates such as styrene-based, polycarbonates, polyolefins, polyethylene terephthalate glycol ester, acrylic and others.
