Abstract
Phase change (hot melt) ink compositions for use in a phase change (hot melt) ink jet recording device are disclosed to comprise: (a) from about 0.1% to about 30% of one or more colorants; and (b) from about 0.1 to about 99.9% of one or more reversibly-crosslinked-polymers. Recording is conducted by thermally melting the ink at a temperature above ambient temperature (20.degree. C.) to provide prints that possess high quality images, scratch resistance, abrasion resistance, low-temperature storage stability and flexibility, offset and pick resistance, adhesion, and other desired properties. Components other than those listed above may be included in the ink compositions to achieve specific printer, substrate, or end use requirements. Furthermore, the present invention also includes methods for the preparation of the above-described inks.
