Embodiment 1

[0017] A water-resistant color digital image inkjet printing medium, comprising a base material coated with a paint layer, wherein the paint layer is formed by uniformly coating the surface of the base material with the following weight components and drying:

[0018] Microporous silica 13%

[0019] Polyvinyl alcohol 17%

[0020] Quaternary Ammonium Cationic Polymer 1.5%

[0021] Auxiliary 0.5%

[0022] water balance.

[0023] The auxiliary agent is a defoamer, and the defoamer is an organosiloxane (or C 18 ~C 22 saturated fatty acids and their ester salts, alkyl sulfonates or castor oil and its derivatives). The base material is color-jet base paper (or double-adhesive paper, double PE coated paper, chemical fiber cloth, cotton cloth, PVC)

Embodiment 2

[0025] A water-resistant color digital image inkjet printing medium, comprising a base material coated with a paint layer, wherein the paint layer is formed by uniformly coating the surface of the base material with the following weight components and drying:

[0026] Microporous silica 18%

[0027] Polyvinyl alcohol 14%

[0028] Quaternary Ammonium Cationic Polymer 2%

[0029] Auxiliary 0.1%

[0030] water balance.

[0031] The auxiliary agent is a defoamer and a whitening agent, and the defoamer is an organosiloxane (or C 18 ~C 22 saturated fatty acids and their ester salts, alkyl sulfonates or castor oil and its derivatives). The base material is PP synthetic paper or PET which has been treated by conventional corona and chemical treatment. The brightener is brightener VBL (or brightener BF). The dosage of the whitening agent is equivalent to 1-50% of the dosage of the defoamer.

Embodiment 3

[0033] A water-resistant color digital image inkjet printing medium, comprising a base material coated with a paint layer, wherein the paint layer is formed by uniformly coating the surface of the base material with the following weight components and drying:

[0034] Microporous silica 15%

[0035] Polyvinyl alcohol 16%

[0036] Quaternary Ammonium Cationic Polymer 1.8%

[0037] Auxiliary 0.3%

[0038] water balance.

[0039] The auxiliary agent is a defoamer, and the defoamer is an organosiloxane (or C 18 ~C 22 saturated fatty acids and their ester salts, alkyl sulfonates or castor oil and its derivatives). The base material is color-jet base paper (or double-adhesive paper, double PE coated paper, chemical fiber cloth, cotton cloth, PVC)

Abstract

The invention discloses a waterproof colorful digital image printing medium. Wherein, the basic material is coated with a paint layer, while said paint layer is formed by uniformly coating the micro-porous silicon oxide, polyvinyl alcohol, ammoniacal positive ion polymer, agent, and water on the surface of basic material to be dried. The invention has better waterproof property, high ink drying speed, better color fixing property, and high image resolution ratio.

Description

Technical field: [0001] The invention relates to a printing medium, which is a color digital image printing medium. Background technique: [0002] The development of electronic digital technology and the popularization of products such as computers, color inkjet printers, and digital cameras have continuously expanded the application range of inkjet printing technology. At present, inkjet printing technology is widely used in indoor and outdoor advertisements, engineering renderings, and daily printing in offices. Home digital image printing and studio photo printing and other fields. As a consumable for color inkjet printers, it is required to have fast ink absorption speed, good ink and color fixation performance, high resolution of printed images, vivid colors, and water resistance. [0003] The color inkjet printing medium is composed of a base material and a coating. The base material mainly plays a supporting role, and at the same time affects the whiteness, opacity a...
