Problems solved by technology

The application of invisible UV anti-counterfeiting fluorescent ink already exists, but the invisible UV fluorescent toner used in laser printers is currently rare
Due to the cumbersome printing process of invisible UV fluorescent ink and the presence of solvents, it is not conducive to the increasingly important environmental protection requirements. The UV fluorescent toner used in laser printers is easy to operate and has no solvent volatilization, which can overcome the above shortcomings, so the market demand is increasing. , it is necessary to develop more invisible UV fluorescent agents and their manufacturing methods

Embodiment 1

[0023] Invisible UV fluorescent toners are prepared by the following steps:

[0024] Step 1: Add 20 parts by weight of inorganic invisible ultraviolet fluorescent yellow pigment purchased from Zhuhai Zhiyuan Pigment Company, 5 parts by weight of polypropylene wax, 1.2 parts by weight of anionic emulsifier and 73 parts by weight of polyester resin to 130 parts by weight of butyl In the ketone, use an emulsification device for high-speed shear dispersion for 1 hour, keep the temperature at about 30 ° C, add 220 parts by weight of deionized water for emulsification, and obtain a mixture dispersion emulsion;

[0025] Step 2: Place the dispersed emulsion of the above mixture in the reactor, adjust the stirring speed to 400-600 rpm, add 35 parts by weight of 1% magnesium chloride solution as a coagulant; after adding the coagulant, adjust the stirring speed to 200-400 rpm, Continue to stir for 30 minutes to obtain aggregated particles with a particle size of 8.6 μm; then add 500 par...

Embodiment 2

[0029] The method for preparing invisible ultraviolet fluorescent toner in this example is basically the same as that in Example 1, except that the fluorescent yellow pigment produced by Zhuhai Zhiyuan Pigment Company in Example 1 is replaced by the inorganic invisible ultraviolet fluorescent green produced by Zhuhai Zhiyuan Pigment Company pigment.

[0030] The invisible ultraviolet fluorescent green toner prepared in this embodiment has a final volume average particle diameter measured by Beckman Coulter of 8.1 μm.

Embodiment 3

[0032] Invisible UV fluorescent toners are prepared by the following steps:

[0033] Step 1: Add 30 parts by weight of organic invisible ultraviolet fluorescent red pigment produced by Shenzhen Bianse Chemical Technology Co., Ltd., 5 parts by weight of polypropylene wax, 1.8 parts by weight of anionic emulsifier and 62.4 parts by weight of polyester resin to 180 parts by weight of In butanone, use an emulsifying device to disperse at high speed for 1 hour; keep the temperature at about 30°C, add 310 parts by weight of deionized water for emulsification, and obtain a mixture dispersion emulsion;

[0034] Step 2: Place the dispersed emulsion of the above mixture in the reactor, adjust the stirring speed to 400-600 rpm, add 42 parts by weight of 1% magnesium chloride solution as a coagulant; after adding the coagulant, adjust the stirring speed to 200-400 rpm, Continue to stir for 30 minutes to obtain aggregated particles with a particle size of 9.6 μm; add 500 parts by weight of...

Abstract

The invention discloses an invisible ultraviolet fluorescence color matching agent and a manufacture method thereof, wherein the invisible ultraviolet fluorescence color matching agent comprises the following raw materials in parts by weight: 60-70 parts of polyester resin with acid value of 5-20mgKOH / g, 1-10 parts of polypropylene wax, 20-30 parts of invisible ultraviolet fluorescence pigment, 0.2-2 parts of dimethylchlorosilane treated silicon powder and 0.5-3 parts of hexamethyldisilazane treated silicon powder, wherein the visible ultraviolet fluorescence pigment has the fineness of 0.5-2mu m in a color matching agent particle and exists in a spherical form. The invisible ultraviolet fluorescence color matching agent has stronger generality and excellent fluorescence intensity and printing property.

Description

Technical field [0001] The present invention involves a method of static photography, electrostatic records, static electrostatic printing such as anti -counterfeiting labels, bills, securities, and commercial confidential documents.Especially invisible ultraviolet fluorescent color tone and its manufacturing method. Background technique [0002] UV fluorescence coloring agent is made of fluorescent compounds to the toner, which can be divided into tangible and invisible ultraviolet fluorescent color tunites.The materials used in formal ultraviolet fluorescence tone are tangible ultraviolet fluorescence pigments. Print images are the same as ordinary laser color tuner.Differential.Invisible ultraviolet fluorescence color tuning agent is made from the corresponding invisible ultraviolet fluorescence compound to the color tubing agent. Its characteristics are that the printed product does not display the color or there is light -colored marks under the normal light source.It will s...
