Cyclic Bisamides Useful in Formulating Inks for Phase-Change Printing

Abstract

Cyclic bisamides may be used to formulate inks for jet ink printing. The cyclic bisamide may be prepared from a cyclic diamine and acylic monocarboxylic acids. Conversely, the cyclic bisamide may be prepared from a cyclic diacid and acylic monoamines. The performance properties of the product may be enhanced by adding some additional difunctional reactant(s), e.g., diacid or diamine. A blend of bisamides may provide better performance properties than either of the component bisamides alone, where the blend includes at least one cyclic bisamide. The bisamides, in combination with an image-forming material, and optionally in combination with other materials, is taken to a molten form and then applied to a substrate to provide a printed substrate.
