Claims
- 1. A method of printing comprising the step of applying a molten composition comprising a diamidediurethane and an image-forming component to a substrate, wherein the diamidediurethane has at least one of the formulas (1), (2) and (3) ##STR5## wherein each of R.sup.1, R.sup.2 and R.sup.3 is independently selected from organic moieties having the formula C.sub.1-50 H.sub.2-102 O.sub.0-15 such that said composition has a melting point of about 40.degree. C. to about 150.degree. C. and a melt viscosity measured at 130.degree. C. of less than about 100 centipoise.
- 2. The method of printing according to claim 1 further comprising the steps of mixing an image-forming component with a diamidediurethane to prepare a hot-melt ink, storing said hot-melt ink in a molten state within a printhead designed for hot-melt printing, and ejecting molten hot-melt ink from said printhead onto a substrate.
- 3. A method of printing comprising the steps of mixing an image-forming component with a composition comprising diamidediurethane to prepare a hot-melt ink, melting the hot-melt ink to prepare molten ink, contacting a flexographic, gravure or intaglio printing plate with molten ink to provide a printing plate having molten ink thereon, and then contacting the printing plate having molten ink thereon with a substrate to transfer an image from the printing plate to the substrate, wherein said composition comprising diamidediurethane comprises at least one diamidediurethane of formulas (1), (2) and (3) ##STR6## wherein each of R.sup.1, R.sup.2 and R.sup.3 is independently selected from organic moieties having the formula C.sub.1-50 H.sub.2-102 O.sub.0-15.
