PHASE-CHANGING INKS CONTAINING CRYSTALLINE TRANS-CINNAMON DIESTERS AND POLYTERPENE RESINS Russian patent published in 2016 - IPC C09D11/02 C09D11/34 C09D11/38 

Abstract RU 2593865 C2

FIELD: printing.

SUBSTANCE: invention relates to phase changing inks, which are solid at room temperature and molten at high temperature of jet printing device. Said inks contain carrier including crystalline trans-cinnamic diester and amorphous polyterpene resin. Trans-cinnamic diester selected from trans-cyclohexane-1,4-dimethanol-trans-cinnamate, para-phenyl-1,4-dimethanol-trans-cinnamate, bis(hydroxymethyl)furan-trans-cinnamate, 2,5-dihydroxymethyl-tetrahydrofuran-trans-cinnamate, trans-cinnamic acid 2,3-butanediol diester, and a mixture thereof. Disclosed inks provide sharp and fast phase transitions from fused liquid state to a solid, high resistance of image to wear and formation of folds when printed paper is bent.

EFFECT: ink hardness value measured using durometer at 25 °C is at least 70.
