Abstract
A water-based, UV-curable ink for plastic substrates, comprising: a) a water-dispersible or water-soluble urethane acrylate oligomer; b) a monomer that is capable of softening the substrate in part or in full; the monomer being resistant to hydrolysis; and c) a passive resin that is soluble in the monomer.

A method for preparing a water-based, UV-curable ink that is capable of adhering to plastic substrates, the method comprising the steps of:
- a) selecting a monomer that is capable of softening the plastic substrate in part or in full and is resistant to hydrolysis;
- b) selecting a passive resin that is soluble in the monomer said passive resin having a Tg between 30.degree. and 130.degree. C.;
- c) dissolving the passive resin in the monomer;
- d) blending the passive resin and the monomer with a water-dispersible or water-soluble urethan acrylate oligomer;
- and
- e) adding water to the blend.
