  • Patent number: 7538145
    Abstract: The phase change, curable composition comprises curable monomer, photoinitiator that initiates polymerization of the curable monomer, and phase change agent that provides the composition with an increase in viscosity of at least four orders of magnitude, from a first temperature, the first temperature being from 50° C. to 130° C., to a second temperature, the second temperature being from 0° C. to 70° C., wherein the second temperature is at least 10° C. below the first temperature. A coating over an image may be applied by providing a composition comprising curable monomer at a first temperature; applying the composition over the image, the image being at a second temperature; and exposing the composition to radiation to initiate polymerization of the curable monomer. In this process, the composition has a viscosity at the second temperature that is at least four orders of magnitude greater than its viscosity at the first temperature.
