Application of thermosensitive color change powder in ink

1 selection of connecting material (resin) : 1.1 influence of viscosity and solid content of binder (resin) on color concentration and surface gloss: The choice of resin in ink oil has a very important effect on the color concentration and surface gloss of temperature-varying ink, which is more significant for black ink. Because the content of pigment in the color changing ink is much higher than ordinary ink, if the resin modulation of ordinary ink color changing ink will lead to...

Description of luminous effect of invisible fluorescent ink substrate

Because the red fluorescence medium in invisible ultraviolet fluorescent red ink is an organic complex, which is easily decomposed by the metal complex bonds of the fluorescent medium under high temperature and hot flashes, the luminescence period of this fluorescent ink depends on the climate and environmental conditions. Invisible ultraviolet anti - counterfeiting fluorescent red ink Because the red fluorescence medium in invisible ultraviolet fluorescent red ink is an organic complex, which is easily decomposed by the metal complex bonds of...

The difference between luminescence, fluorescence and reflection

When the setting sun fades away, when the night falls and the lights come on, I suddenly find that the city at night is so beautiful that compared with the day, it seems to have a soft, romantic charm. As the finishing touch pen, of course, is the light, a variety of, colorful light. Light is different, too. There are spontaneous light, luminescence is a non-thermal emission of materials, the main application field is in the light source, display devices,...

How to use glow in dark powder to achieve good results

Glow in the dark powder is a kind of luminous material. But sometimes the user can reflect to use the effect is not good, actually want to make the effect of noctilucent powder better play. Should depend on its actual situation and decide, different requirement, luminance and different use have different use method. Here is a brief introduction. 1 glow in dark powder as a kind of light storage luminous material, so luminous powder again good also have to absorb light. Electric...

About electroluminescent powder

From the perspective of luminescent materials, electroluminescence can be divided into non-electroluminescence and organic electroluminescence. Electroluminescent materials are generally such as semiconductor materials. Organic electroluminescent materials depend on the molecular weight of organic luminescent materials It can be divided into small molecules and macromolecules. Organic dyes or pigments are used as light-emitting materials for small-molecule OLED materials, and conjugated or non-conjugated polymers (polymers) are used as light-emitting materials for polymer materials. PPV and its derivatives are typical high-molecular light-emitting materials. Organic...

The difference between electroluminescence and photoluminescence

1. Electroluminescence is different from photoluminescence in that electroluminescence refers to electroluminescence and photoluminescence refers to the luminescence of photoluminescence materials. The principles of electroluminescence and photoluminescence are different. 2. Electroluminescence, also known as electric field luminescence, or EL for short, is a physical phenomenon in which the electrons excited by the electric field hit the light center by the electric field generated by the voltage applied to the two electrodes, resulting in the transition, change and compound of electrons...
