Printed product and aqueous coating agent

Abstract

Disclosed is a textile printed product using an ink for an inkjet textile printing pigment containing an anionic resin. The textile printed product is improved in washing fastness and rubbing fastness, while also being improved in chemical resistance to acidic / basic solutions. Specifically disclosed is a printed product which is obtained by textile printing a washable fabric material using an inkjet process. The printed product is characterized by comprising the fabric material, a print layer printed on the fabric material by an inkjet process using an aqueous pigment ink containing an anionic resin, and a coating layer which is obtained by applying an aqueous coating agent, which contains nonionic aqueous resin particles, onto at least one of the upper and lower surfaces of the print layer.

Description

technical field [0001] The present invention relates to an inkjet printed matter and a water-based coating agent used in the printed matter. Background technique [0002] Conventionally, in the case of commercial printing, printing by screen printing has been widely used. In addition, inks containing high-viscosity binders are generally used in screen printing. Therefore, when printing on a medium such as cloth, printing with high wash fastness can be performed. [0003] Inkjet printing on media such as cloth is being studied. However, in order to improve the ink and use it for inkjet applications, it is necessary to lower the viscosity. However, if the viscosity of the ink is lowered, there will be problems such as a decrease in fastness to washing. [0004] In addition, inkjet printing is a system in which ink is ejected from fine holes, so the volume of adhesive on the surface of a medium such as cloth is reduced at a discharge amount that can be tolerated in actual u...

AI Technical Summary

Problems solved by technology

Therefore, in actual use such as washing, the surface may physically peel off, and sufficient washing fastness and rubbing fastness may not be ensured.

[0005] Like this, there is usually a trade-off relationship between the improvement of fastness and the reliability of operation that is accompanied by an increase in the viscosity of inkjet inks, and therefore, obtaining a printed matter capable of exhibiting commercial quality with only ink alone is a technical up is difficult

[0006] In addition, when the terminal group of the polymer-based coating agent is anionic, there may be a problem that it is easily eluted in an acidic environment. Therefore, it is desired to obtain a coating agent with acid resistance.

[0007] In the case where the terminal group of the polymer coating agent is cationic, there may be a problem that it is easily eluted in an alkaline environment, so it is desired to obtain a coating agent with alkali resistance
