Abstract

The invention discloses a laser printing medium, a preparation method of the laser printing medium and coating layers. The laser printing medium comprises a substrate and two coating layers, namely a first surface coating layer and a second surface coating layer, which are respectively coated on two surfaces of the substrate, wherein the first surface coating layer comprises inorganic pigment, water-based polymer, an anti-static agent, water and organic silicon emulsion and / or emulsifying wax; the second surface coating layer comprises inorganic pigment, water-based polymer, anti-static agent, water and organic silicon emulsion and / or emulsifying wax; a surface roughness Ra value of the first surface coating layer is 0.08 to 1.5 mum; a surface roughness Ra value of the second surface coating layer is 1.6 to 3.0 mum; a difference value of the surface roughness of the two coating layers is not less than 0.6 mum. According to the laser printing medium disclosed by the invention, not only can good printing quality be obtained, but also paper cannot be jammed during continuous high-speed printing, and particularly, the advantages of the laser printing medium can be more obvious when plastic resin such as PET (Poly Ethylene Terephthalate) is used as the substrate.

Description

technical field

[0001] The invention specifically relates to a laser printing medium, its preparation method and coating. Background technique

[0002] Laser printer is a kind of printing output equipment, its working principle is based on electrophotography technology, that is toner is absorbed by positive and negative charges, and after a series of transfers, it reaches the surface of the printing medium and is heated on the hot roller (the temperature is usually as high as 180°C). , The toner is solidified under pressure, and finally the required graphic image is formed on the surface of the medium. Among them, the image quality of color laser printing is good, the printing speed is fast, the image is not easy to fade, and the storage time is long. It is a digital printing method that has developed rapidly in recent years and can be used in different fields, such as advertising, packaging, licenses, medical imaging films, etc. .
