Problems solved by technology

) insufficient, poor ejection stability or spots, and problems such as ink solidification in the waste liquid tube
[0011] In addition, in the conventional technology, when the ink is filled in the printer for a long period of time, the ink attached to the maintenance components of the printer dries and accumulates, and the waste liquid pipe, etc. are clogged, causing inconvenience during maintenance.

Abstract

The present invention addresses the problem of providing a nonaqueous ink-jet ink composition which, even when used in high-speed printing on an object to be printed, the ink-receiving surface of which is constituted of, for example, a vinyl-based polymer such as a poly(vinyl chloride)-based polymer or an ethylene / vinyl acetate copolymer, is excellent in terms of thin-line-print reproducibility, solid printing, mottling prevention, abrasion resistance, and solvent resistance and which is excellent also in terms of delivery stability and dry-coat resolubility and has a high ignition point. Provided as the solution means is a nonaqueous ink-jet ink composition which includes an acrylic resin, a ketone-based resin, a pigment, and a pigment dispersant and further includes propylene carbonate and a diethylene glycol dialkyl ether as organic solvents.

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 ...
