Problems solved by technology

These solvents have a low boiling point and dry quickly, so that the pigment and resin in the oil-based ink are easy to precipitate on the surface of the nozzle hole, causing the nozzle to be blocked or sprayed obliquely.
Moreover, due to their strong solubility, these solvents are easy to dissolve and corrode the parts of the inkjet printer such as pipelines, sub-ink cartridges, and nozzle glue.
This leads to problems such as poor printing quality on the substrate and shortened machine life.

Abstract

The invention discloses a digital painting ink combination containing color dispersion liquid, wherein, at least 70wt percent of mixed organic solvent is contained. The mixed organic solvent contains glycol butyl ether acetate ester and a solvent pertaining to lactone line or contains glycol butyl ether acetate ester and a solvent pertaining to pyrrolidone line. The combination has smooth painting, thereby being applicable to printing in polyvinyl chloride substrate, and has excellent printing quality, printing stability, printing ink dryness and storage stability.

Description

technical field [0001] The invention relates to a digital inkjet ink composition, and also relates to the application of the digital inkjet ink composition on a polyvinyl chloride substrate. Background technique [0002] In the field of digital inkjet printing, inkjet printers can be divided into thermal foam type and micro piezoelectric crystal type (drop-on-demand method) according to the working principle of the nozzle. [0003] Generally speaking, the inks used for digital printing mainly include dye-based water-based inks with water as the main solvent and pigment-based oil-based inks with organic solvents as the main solvent. Dye-based water-based inks are mainly used in thermal foam nozzles, which have the problems of poor light fastness and water fastness. In addition, the drying time of water-based inks is long due to the low volatilization rate of water, and the substrates suitable for water-based inks have certain limitations. The limitation is that it must be a ...
