Abstract

The object of the present invention is to provide a non-aqueous inkjet ink composition that can be printed at a high speed even with respect to a printed matter composed of a polyvinyl chloride-based polymer or an ethylene-based polymer such as an ethylene-vinyl acetate copolymer. When printing, it is also excellent in fine printing reproducibility, solid filling property, anti-mottling (mottling), rubbing resistance, and solvent resistance of printed matter, and it is also excellent in ejection stability and resolubility of dry coating film. high. As a solution, a non-aqueous inkjet ink composition is provided, which contains an acrylic resin, a ketone resin, a pigment and a pigment dispersant, and contains propylene carbonate and diethylene glycol dialkyl ether as an organic solvent.

Description

technical field [0001] The present invention relates to a non-aqueous inkjet ink composition suitable for producing large-format signboards and the like whose printing surface is mainly composed of vinyl chloride polymers or ethylene-vinyl acetate copolymers, and printed matter obtained using the same. Background technique [0002] In recent signboard advertisements, in addition to bright and refined logos and patterns, photo-style elements such as the appearance of products and faces of people have increased. Furthermore, in order to give the viewer a stronger impact, the size of the signboards gradually appeared in very large format signboards. [0003] In the past, as a method of making signboard advertisements, it was common to cut colored sheets into letter shapes for signs and paste them, and it was common to use various printing machines for photo-styles. However, there is a problem that a lot of time and effort are required for production, and large-scale equipment ...
