Problems solved by technology

[0014] However, in the conventional technology, it is not possible to obtain a processing liquid satisfying all the above-mentioned characteristics, especially a processing liquid that can guarantee the characteristics of 1) to 4) and can perform the inkjet discharge of 5) at the same time.
In addition, it is also a fact that a treatment liquid that sufficiently satisfies storage stability cannot be obtained.

preparation example Construction

[0041] For example, cationic polyurethanes obtained by the following preparations (1) to (2) and the like are mentioned, and an aqueous dispersion which is a composition obtained by dispersing cationic polyurethanes in water is particularly preferable.

[0042] The preparation of cationic polyurethane is as follows: (1) use polyisocyanate (A) and polyester polyol (B1) as polyol for polyurethane reaction, and use chain extender (C) with tertiary amino group simultaneously to prepare polyurethane In the prepolymer, a part of the tertiary amino groups is neutralized with an acid or quaternized with a quaternizing agent so that the amine value is in the range of 1 to 40 (KOHmg / g), whereby a cationic polyurethane can be obtained in the form of a composition. In addition, (2) using the polyisocyanate (A), the polycarbonate polyol (B2), the chain extender (C) having the tertiary amino group, and the polyisocyanate containing 50% by mass or more of ethylene oxide chain The alkylene ox...

Abstract

The aim of the invention is to provide an ink jet treatment liquid which can be jetted and has adhesion force, bonding property, transparent property and drying property after jet relatively to the non-absorptive printing medium of ink and simultaneously has storing stability. The ink jet treatment liquid contains a cationic polyurethane, a polyamine and / or a polyamine derivative.

Description

technical field [0001] The present invention relates to coating of a non-absorbing film-based material suitable for ink, and more specifically, to an inkjet treatment liquid, an inkjet recording method using the treatment liquid, and a recorded matter. Background technique [0002] The inkjet recording method is a method of recording images, characters, etc. by ejecting tiny droplets from nozzles and making them adhere to various recording media. It is easy to increase speed, reduce noise, and increase color. The feature that non-contact printing can be performed on non-recording media can be used in various applications as a recording device for various images. [0003] Especially for industrial use, the image formed by the full-color inkjet recording method can also be obtained close to the image of the multi-color printing or the silver salt photo method by the plate-making method, and in the case of printing in a variety of small quantities General multi-color printing ...
