Abstract: An ink composition and application method are described which enable the printing of high-resolution images on a variety of substrates (especially plastics.) The composition basically includes an ultra-violet curable adhesive in combination with a selected dye pigment and one or more solvents. The composition is preferably applied using a thermal ink jet delivery system. After application, the composition is exposed to ultra-violet light, resulting in the formation of a permanent image. The materials and methods of the invention are capable of producing a high-resolution image without causing damage to the substrates.
