Abstract
The present invention relates to a method for manufacturing an inkjet-printed substrate, wherein a liquid treatment composition comprising at least one acid and an ink are deposited onto a substrate simultaneously or consecutively by inkjet printing, wherein the substrate comprises a coating layer comprising a salifiable alkaline or alkaline earth compound.
Claims15
A method for manufacturing an inkjet-printed substrate comprising the following steps:
- a) providing a substrate, wherein the substrate comprises on at least one side a coating layer comprising a salifiable alkaline or alkaline earth compound,
- b) providing a liquid treatment composition comprising an acid,
- c) providing an ink,
- d) depositing the liquid treatment composition onto the coating layer by inkjet printing to form a first pattern, and
- e) depositing the ink onto the coating layer by inkjet printing to form a second pattern, wherein the liquid treatment composition and the ink are deposited simultaneously or consecutively and the first pattern and the second pattern overlap at least partially.
