specific Embodiment approach 1
[0010] Embodiment 1: In this embodiment, the ink-absorbing layer material for inkjet recording is made of sericite, dispersant and binder, wherein the mass ratio of dispersant to sericite powder is 0.02~0.05:1, and the binder and The mass ratio of sericite powder is 1:1~1.5.
specific Embodiment approach 2
[0011] Embodiment 2: This embodiment is different from Embodiment 1 in that: the dispersant is acetic acid, boric acid or polyacrylic acid emulsion. Others are the same as in the first embodiment.
specific Embodiment approach 3
[0012] Specific embodiment three: the difference between this embodiment and specific embodiment one or two is that the binder is one of polyvinyl alcohol, modified polyvinyl alcohol, starch, modified starch, styrene-butadiene latex, and gelatin or a mixture of two of them.
[0013] When the binder described in this embodiment is a mixture, various binders are mixed in any ratio.

The invention relates to an ink jet recording ink-absorption layer material and a preparation method thereof, belonging to the field of ink jet recording materials. The invention solves the problems that the existing ink jet recording material has the defects of non-uniform color distribution, image diffusion, scraggly feeling of images touched by hands and poor wear resistance and has high preparation cost. In the invention, the ink jet recording ink-absorption layer material is prepared from sericite, dispersing agent and binding agent. The preparation method of the invention is as follows:1, preparing sericite powder; 2, preparing sericite suspension; 3, preparing coating solution; and 4, coating the coating solution after the treatment of substrate plasma, and then drying to obtain the ink jet recording ink-absorption layer material. The invention has the advantages of easily obtain raw materials, low cost and easy preparation. The ink jet recording ink-absorption layer material of the invention has the advantages of clear printed images, no ink droplet diffusion, even color distribution, smooth surface of images, no crack and smooth hand-touch feeling.
Description
technical field [0001] The present invention belongs to the field of inkjet recording materials. Background technique [0002] The inkjet recording material is mainly composed of an ink-absorbing layer, a primer, and a base material. There are many ways to classify ink-absorbing layers for inkjet recording, and they can be classified into resins and pigments. Resin ink-absorbing layer refers to coating polyvinyl alcohol, gelatin and other resins on the printing material, often called expansion type. Although its clarity is high, its ink absorption speed is slow. The pigment ink-absorbing layer mainly contains specific pigment particles, such as silica, alumina, etc., forming a network containing a large number of micropores in the coating, which absorbs and fixes the ink droplets printed, often called It is a void type with good ink absorption performance, but the gloss is not high. With the development of computer technology, digital imaging technology and network techn...
