Powder composition and process of forming liquid ink image using same

Abstract

A powder composition containing a powder of a modified polymer having a recurring unit containing at least one carboxyl group, the carboxyl groups of part of the recurring units being in the form of a salt with an aliphatic amine having at least 6 carbon atoms, and a powder of a surfactant. The powder composition is used for forming an image on a printing medium, in which method the composition is applied over a surface of a transfer medium to form a layer of the powder. An image of a liquid ink capable of dissolving or swelling the powder is then formed on the layer so that the viscosity of the liquid ink increases when contacted with the powder. The image on the transfer medium is contacted with the printing medium so that the image is transferred to the printing medium.
