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 BME100L) 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, an...

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 and pre-disperse for 1 hour, and then use a high-speed shear disperser (Shanghai Weiyu Company BME100L ) 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...

Abstract

The invention discloses a toner adhesive layer for laser printing, which comprises a base material and a toner adhesive layer coated on the surface of the base material. It is evenly coated on the surface of the substrate, and after drying to remove water or solvent, it is a solid coating that is firmly attached to the surface of the substrate. The toner bonding layer coating solution is a mixture of binder solution and pigment slurry. , adding a mixture of curing agent and wetting agent. The beneficial effects of the present invention are that the laser printing medium made with the toner adhesive layer, and the photos or images made by a laser printer or a digital printing machine, have high color saturation, high imaging definition, good water resistance, and can be used for a long time. save.
