REACTION LIQUID, INK AND REACTION LIQUID SET, JET PRINTING DEVICE AND IMAGE FORMATION METHOD Russian patent published in 2010 - IPC C09D11/00 B41J2/21 

FIELD: chemistry.

SUBSTANCE: reaction liquid used with ink contains a dye and which destabilises the dissolved state or dispersion state of the dye in the ink when in contact with ink on a printing carrier. The reaction liquid contains at least calcium ions, glycerin and polyethylene glycol with average molecular weight between 200 and 1000 inclusively. Content of calcium ions A (wt %) lies between 2.7 wt % and 4.3 wt % inclusively per total weight of the reaction liquid. Total content of glycerin B (wt %) and polyethylene glycol C (wt %) per total weight of the reaction liquid is at least 6 times more and not more than 11 times greater than content of calcium ions A (wt %). The ratio of content of glycerin B (wt %) and total content of glycerin B (wt %) and content of polyethylene glycol C (wt %), (B/(B+C)), lies between 0.3 and 0.7 inclusively.

EFFECT: invention provides high quality of the image obtained on printing material, and also avoids deposit formation.
