Embodiment Construction
[0017] Below in conjunction with accompanying drawing, the structure and the principle of use of image paper base paper provided by the present invention are described in further detail:
[0018] Such as figure 1 Shown is a schematic diagram of the cross-sectional structure of the single-sided image paper base paper provided by the present invention. That is to say, the structure that constitutes the base paper of the image photo paper includes kraft paper with a thickness of 160-170 g / m2 as the base material 1, and a white pulp vermiculite layer with a thickness of 30-50 g / m2 coated on one side of the base material. 2. It is used to cover up the black and yellow color of the kraft paper base material and level its flatness, so as to avoid the interference of this variegated color on the image color formed by the imaging layer; the thickness of the above-mentioned white pulp hanging surface for waterproofing and moisture-proofing is 30 - PE (polyethylene) film waterproof laye...

Abstract
The invention belongs to the technical field of photographic paper, and particularly discloses an image photographic base paper. The image photographic base paper is single-sided photographic base paper structurally comprising a base material, a white paper pulp surface coating one side of the base material, a waterproof layer on the white paper pulp surface layer, an ink absorption imaging layer on the waterproof layer, and a polypropylene (PP) aluminized film layer at the other side of the base material; or the image photographic base paper is double-sided photographic base paper comprising a base material, two white paper pulp liner layers which are sequentially arranged at the two sides of the base material, a waterproof layer on the white paper pulp surface, and an ink absorption imaging layer on the waterproof layer. After the image photographic base paper is adopted, the imaging demand of high-quality image photographic paper can be met, the production cost is low, and the image photographic base paper is in accordance with the requirement on environmental protection.
Description
technical field [0001] The invention belongs to the technical field of photographic paper, and relates to an image photographic paper base paper suitable for advertisement and image production. Background technique [0002] At present, it is suitable for various advertisements and image production. The base paper structure of photo paper used in inkjet printing is white cardboard made of pure wood pulp as the base material. On both sides of the base material, PE film and PVA Ink-receptive imaging layer construction. The base material used for this kind of photo paper base paper is made of pure wood pulp, and the preparation process is extremely strict, so there are defects of high production cost (currently about 12,000-15,000 yuan / ton) and relatively complicated production process. Especially the use of wood pulp requires the use of a large number of trees, which will affect the ecological balance. Contents of the invention [0003] The purpose of the present invention ...
