Problems solved by technology

[0002] At present, the coatings used for imaging on paper or other synthetic films are mainly obtained in two ways: one is the traditional photosensitive silver salt coating, which can obtain photos with good color reproduction and high definition, but the cost is high , the coating structure is complex, there are many imaging processes, the imaging speed is slow, the storage life after imaging is short, and the processing process is accompanied by chemical waste liquid, which pollutes the environment
The other is the coating used for inkjet printing. The cost of the coating obtained in this way is low, and the imaging effect can basically meet people’s requirements for printing text or photo images, but using this coating technology to print images or photos, The speed is very slow, the imaging efficiency is low, and the coating is poor in water resistance and preservation
[0003] Laser printing technology has the advantages of fast printing speed, clear printing, high printing image quality, good color saturation stability, and low image noise. However, due to the relatively low resolution of laser printing in the early stage, it is mainly used for graphic printing at present.

Embodiment example 1

[0029] Take the coating preparation of special photo film for laser printing as an example:

[0030] 1. Prepare adhesive solution: Add 12 parts of pure water and 28 parts of water-based polyurethane into a stainless steel bucket, stir for 15 minutes and then disperse for 30 minutes;

[0031] 2. Preparation of pigment slurry: Add 0.1 part of dispersant to 28 parts of pure water and stir evenly, slowly add 32 parts of white nano-pigment, stir, pre-disperse and mix evenly, and then use a high-speed shear disperser (Shanghai Weiyu Company BME 100L) was dispersed for 1 hour to obtain a pigment slurry;

[0032] 3. Prepare toner adhesive layer coating solution: mix the above adhesive solution and pigment slurry, add 0.1 part of curing agent and 0.3 part of wetting agent, stir in a circular motion, and defoam at rest to obtain a toner adhesive knot coating solution;

[0033] 4. Use a film applicator to apply the toner adhesive layer coating solution to both sides of the PET sheet, a...

Embodiment example 2

[0035] 1. Preparation of adhesive solution: Add 45 parts of ethanol into a stainless steel bucket, add 25 parts of PVB while stirring, stir for 1 hour, start to heat up to 40°C and maintain for 1 hour, cool to room temperature, and obtain PVB solution ( binder solution);

[0036] 2. Prepare pigment slurry: Add 0.1 part of dispersant to 20 parts of ethanol and stir evenly, slowly add 8 parts of white nano-pigment, continue to stir, pre-disperse for 1 hour, and then use a high-speed shear disperser (Shanghai Weiyu Company BME 100L) was dispersed for 1 hour to obtain a pigment slurry;

[0037] 3. Prepare toner adhesive layer coating liquid: mix adhesive solution and pigment slurry, add 1 part of wetting agent, circulate and stir evenly, static defoaming, and prepare toner adhesive layer coating liquid;

[0038] 4. Use a film applicator to apply the toner adhesive layer coating solution to the paper base, and the coating moisture is 40g / m 2 , the dry weight is 8g / m 2 ; After dr...

Abstract

The invention discloses an ink powder bonding layer used for laser printing. The ink powder bonding layer comprised a base material and the ink powder bonding layer coated on the surface of the base material. The ink powder bonding layer is formed in a manner that ink powder bonding layer coating liquid is coated on the surface of the base material, water or solvent of the coating liquid is removed via a drying process, and then a solid coating firmly attached on the surface of the base material is formed. The ink powder bonding layer coating liquid is prepared in a manner that an adhesive solution is mixed with pigment slurry, and curing agents and wetting agents are added to form the mixed liquid. The beneficial effects of the ink powder bonding layer are that: laser print medias prepared by the ink powder bonding layer, and photos and images prepared via a laser printer or a digital printing machine are of high color saturation, high imaging sharpness and good waterproof performance, and can be long preserved.
