Embodiment Construction

[0058] The invention adopts ultraviolet light curing technology to realize the drying of frequency conversion ink in various printing methods such as offset printing, gravure printing, silk screen printing, flexo printing, embossing printing and the like.

[0059] The prepolymer in the ink can be transferred well on various printing machines, the diluent is highly active and low toxic, and a high-efficiency photoinitiator is selected, making the fluorescent frequency conversion anti-counterfeiting ink an ink system suitable for UV curing.

[0060] The composition of this ink includes ultraviolet fluorescent pigments and / or infrared up-conversion materials, light-cured acrylic resins, acrylate monomers, photoinitiators, fillers and ink additives, which endow the ink with good printability, excellent UV curing instant drying performance and anti-counterfeiting recognition function.

[0061] 1. Pigment: In the present invention, ultraviolet fluorescent pigment and / or infrared lum...

Abstract

The invention provides a UV solidified stealth fluorescent frequency conversion ink, wherein the components include (by weight percent): 5-8% of ultraviolet fluorescent pigment and / or infrared transformation pigment, 5-50% of connection material, 1-40% of methyl acrylate monomer, 0.5-30% of photo-initiating agent, 0.1-55 of amine initiation promoting agent, 0.5-30% of filler, and 0.5-10% of stabilizing agent.

Description

technical field [0001] The present invention relates to an ink based on artificial resin. Background technique [0002] Infrared luminescent pigments (infrared up-conversion pigments) are colorless under visible light, emit visible light under the condition of 800-1500nm infrared light, absorb wavelength peak at 980nm, and emit red light with a wavelength of 610-630nm, or 370- 440nm blue light can also be 530-560nm green light. Ultraviolet fluorescent pigments are also colorless under visible light, and red, yellow, blue, green, and cyan under 365nm ultraviolet light. Fluorescent ink uses this principle to make the ink produce colored fluorescence under the excitation of infrared light or ultraviolet light. UV curing invisible fluorescent frequency conversion ink is a kind of fluorescent ink. Usually, the printed pattern is colorless and transparent, and it presents different colors with the frequency of the detection light source. The ink can change color under the excit...
