Abstract:

An ink is disclosed for producing an ink jet print receptive surface on coated or coated polymer substrates such as CD-R substrates. The ink comprises a solid water soluble salt of acrylamidoalkanesulfonic acid, one or more ethylenically unsaturated monomers or oligomers capable of being photopolymerized by ultra-violet radiation, one or more functional extender pigments, and one or more photoinitiators. A modified silicone may be added to the ink to control the spread of the ink-jet print and the print definition. The inks are hardened by exposure to ultra-violet light. The ink may be over-printed with thermal drop-on-demand ink-jet printers.
