The holographic pigment is an ultra-fine powder with a thickness of about 2-3um, which can give your finished product an amazing linear rainbow hologram effect.
As a pigment decoration product, it has been widely used in cosmetics, printing and coating, automotive paints, and many other fields.
In addition to holographic laser powder, our company also provides magnetic holographic pigment and holographic nail powder to cater to different market applications.
Compared with traditional metallic pigments, the holographic pearl pigment produced by our company has better dispersion in resin, providing a brighter and more reflective surface. And none of them have a substrate and are very thin. When customers use it, the consumption will be small.
It’s also known as optical diffraction powders, or structural color powders, because the color effects we see are produced by micro-nano optical technology, showing different colors and 3D effects through micro-nano structures.
| Features of Holographic Laser Powder |
- Particle size: 20-75 micron, shape: irregular.
- Powder thickness is about 2um, has better reflective effect.
- No base film, and the coating is very thin, so consumption is very small when using it.
- Smooth surface, chrome-like mirror effect and high-reflective.
- Create a beautiful inear rainbow effect while using on products.
- Sealed in a small acrylic container for easy application and storage.

Note: the powder size probability is normal distribution, and the powder with a smaller grain size is allowed.
Selection of anilox roller
For ink or resin with optical diffraction powder, compared with ordinary pure ink, the mesh diameter and depth are a little larger, and the mesh diameter size should be larger than the powder size. Laser engraving type should be selected for anilox roller, and the effect of hexagonal and U-shaped mesh will be better. Different mesh diameter, mesh depth, mesh angle, mesh shape, and other plate-making factors affect the final effect.

| Size | Mesh number |
| 75 um | 200 |
| 50 um | 300 |
| 35 um | 400 |
| 25 um | 500 |
| 15～20 um | 700 |
Proportion
The holographic pearl pigment is suitable for coating, spraying, silk screen printing, gravure printing, and other processes. The addition proportion is 0.3 ~ 10%. The proportion can be determined according to the required effect. The addition proportion is small, showing a flashing effect. When the addition amount is large, the loose powder is dense, and there will be an aperture halo effect. The strength of the effect is also positively related to the coating amount. (Note: powder is not suitable for offset printing at present)
Dissolution method
- Dissolution sequence: powder infiltration → transfer in resin ink
- When used in the organic solvent system, the powder can be soaked with the organic solvent (such as ester, ketone, etc.) fused with the system. The soaking time shall not be less than 2 hours, and it shall be fully stirred to improve the dispersion. The wetted powder is evenly added to the resin ink in proportion, and suitable dispersant or coupling agent is allowed to be added. It is recommended to use “propylene glycol or propylene glycol methyl ether” as a wetting agent, and its slurry is effective after being sealed and stored at room temperature for 6 months.
- When used in the aqueous system, it is recommended to infiltrate the powder with purified water and stir it fully, so that the powder can be more evenly dispersed, and the soaking time shall not be less than 2 hours. The wetted powder is added to the resin ink in proportion, allowing the addition of appropriate dispersant or coupling agent.
- In actual use, if ethanol is needed as the diluent, it is recommended to use it when the concentration is less than 10%, and do not store the solution containing ethanol for a long time.
- When used in an aqueous resin system, avoid wetting the powder with solvents such as ethanol, organic ester, ketone, and toluene, and do not use tap water as the wetting agent.
- The PH value of the solution containing powder is recommended to be about 7 to avoid acid-base erosion.
Other physical properties
Temperature resistance: the holographic glitter pigment is produced online, the temperature resistance is about 180 ℃, and the drying method is unlimited.
Solvent resistance: it can be used in organic and inorganic solvents, such as esters, ketones, alcohol, water, etc.
