Problems solved by technology

For example, U.S. Patent No. 4,503,111 introduces the use of polyvinyl alcohol pyrrolidone as the ink-absorbing layer of the recording medium. It also has disadvantages, such as slow drying of the image, too much viscosity of the ink-absorbing layer, and adhesion when the paper is stacked.
[0009] For ordinary materials, white fillers are added to adjust the transmittance of the medium, which will inevitably affect the quality of the image, causing the printed image to be viewed from the back. When the light box is not turned on, the color is not bright and the image is pale.

Embodiment 1

[0021] The ink-jet receiving material in the present invention comprises upper and lower ink-jet receiving systems, the upper layer is a permeable covering layer containing fillers and water-soluble resins, and the lower layer is a dye-accepting layer containing hydrophilic resins and cationic resins. The weight value of each component in the two layers can be set according to specific needs. The hydrophilic resin is one or more of gelatin, vinyl alcohol polymers, and cellulose derivatives. The cationic resin is used as an ink-fixing agent. The cationic resin used as ink fixing agent is at least one acrylic monomer or oligomer or polymer selected from polyvinylpyrrolidone, primary to tertiary amine or quaternary ammonium salt, allylamine, diallylamine and chlorinated diene Polymers and copolymers of amine monomers of propyldimethylamine. The weight ratio of hydrophilic resin and ink fixing agent in the dye receiving layer is 20:1. The transparent base is a polyester base. ...

Abstract

The invention publicizes a kind of spraying ink accepting material and back spraying lamp house slice made up of the material . The spraying ink accepting material includes two layers of spraying ink accepting system , the top layer is a penetration covering layer that contains stuffing and water--solubility resin , the bottom layer is a dye accepting layer that contains hydrophilicity resin and cation resin . The back spraying lamp house slice includes transparent substrate with pre-scribble cohering layer , on the transparent substrate spreads dye accepting layer that contains stuffing and water--solubility resin , on the substrate scrawls penetration covering layer that contains stuffing and water--solubility resin . Because the invention has adopted the stated spraying ink accepting material and back spraying lamp house slice , when typing color tests piece of specimen page on different printer , and test the color density of yellow , rank , blue and black on the coating (front) and slice base (back) , all the back spraying penetrating effects of the tested specimen page are great .

Description

technical field [0001] The invention relates to a receiving material and a back-sprayed lamp box sheet suitable for ink-jet printers, which are used in the advertising industry to make light box advertisements, business exhibitions, photo studios and personal digital photo displays and decorations. Background technique [0002] Currently, inkjet printers are becoming more and more popular due to their many advantages, especially their high-speed printing without noise and without additional development or other procedures. The use of multiple nozzles makes it suitable for many aspects of work. Inkjet printers with small pores on the nozzle are very important, and many methods of ejecting ink droplets have been invented, such as electrostatic attraction technology, piezoelectric technology, and thermal bubble technology. Therefore, people need the emergence of this high-speed, low-noise, multi-color printing technology. [0003] Inkjet needs to consider three factors: print...
