Embodiment 1

[0024] According to the invention process, a kind of medium gloss inkjet printing paper with good adaptability of pigment ink is prepared, and the steps are as follows:

[0025] S1: Preparation of coatings: prepare ink-absorbing layer and glossy layer coatings respectively according to the formula. The preparation of the ink-absorbing layer coating is: parts by weight: SiO2: 100-110 parts, PVA aqueous solution: 225-235 parts, VAE emulsion: 55-65 parts, color fixing agent: 50-60 parts, whitening agent: 3 to 5 parts, defoamer: 0.6 to 0.7 parts, deionized water: 530 to 550 parts; at room temperature, add SiO2 and color fixing agent together to deionized water and stir for 45 minutes, then add PVA aqueous solution and VAE emulsion to mix The prepared adhesive and whitening agent are finally added to the defoaming agent, stirred and mixed evenly, and the ink-absorbing layer coating is obtained. Wherein the adhesive and defoaming agent are added while stirring, and the stirring spe...

Embodiment 2

[0031] The performance of the good middle gloss inkjet printing paper of the pigment ink adaptability prepared in embodiment 1 is measured, and the results are as follows:

[0032] Gloss (75°) (%): 15.8

[0033] Whiteness (CIE, D65 / 10°): 95

[0034] Opacity (%): 96.66

[0035] Smoothness (s): 25.4

[0036] Water resistance (%): 22

[0037] Bleeding: 6.1

[0038] Color density: 0.92 / 1.15 / 1.05 (cyan / magenta / yellow).

[0039] Therefore, the printing paper prepared by the process of the invention not only has good pigment ink adaptability, but also has good performance indexes. The paper surface has a suede effect, which makes the printed picture on the paper soft and will not be glaring due to strong light. It is especially suitable for outdoor advertising and high-end business promotion. Pigment ink can resist ultraviolet erosion, strong color retention and long color retention time; it can also meet the needs of printing and collecting precious photos and commemorative pa...

Abstract

The invention discloses a process for making medium-gloss ink-jet printing paper with good pigment ink adaptability. The process comprises the following steps: preparing an ink absorbing layer coating, preparing a gloss layer coating, smearing an ink absorbing layer, carrying out drying, carrying out matte treatment, smearing a gloss layer, and the like. The ink-jet printing paper made by using the process disclosed by the invention is capable of solving problems of coloring and color fastness in pigment ink printing, has good pigment ink adaptability and is easy to color, and a printed pattern is good in ultraviolet resistance, good in coloring fastness and long in color lasting time. In addition, the gloss layer is smeared twice, so that a paper surface has a suede effect, the problem that incident light can be reflected on paper and boards of advertisements can be solved, the vision effect of the printed pattern can be improved, and special requirements for making paper and boards of advertisements can be met.

Description

technical field [0001] The invention relates to a process for preparing color ink-jet printing paper, in particular to a process for preparing medium-gloss ink-jet printing paper with good pigment ink adaptability. Background technique [0002] With the development of digital imaging technology, the demand for color inkjet printing paper is increasing. Color inkjet printing paper is a kind of coated processed paper. It is coated and processed on the basis of ordinary printing paper. It is mainly coated with paint on its surface so that it can absorb water-based ink and prevent ink droplets Diffusion to the periphery, thereby maintaining the original color and clarity intact. [0003] At present, the inkjet photo paper on the market is divided into matte color inkjet printing paper, medium gloss color inkjet printing paper and high gloss color inkjet printing paper. Among them, the medium gloss color inkjet printing paper is mainly used for advertising, and the application v...
