‘Preamber’ Lucid pearlescent effect pigment：A new generation of fourth category pigment 

In the forefront of modern materials science, photonic crystal materials have gained significant attention for their excellent color-changing properties and captivating color displays.

The latest effect pigment product from PNM, ‘Preamber’ lucid pearlescent effect pigment, represents an innovative breakthrough in this field. With its unique structural color effect, it stands out in the market, offering a wide range of colorful options for various applications.

PART 01 ‘Preamber’  Lucid Pearlescent Effect Pigment

We categorize common pigments into the following four types: absorptive pigments, metallic effect pigments, and pearlescent effect pigments. Absorptive pigments display color by absorbing specific wavelengths of light. Metallic effect pigments exhibit a metallic sheen through the reflection and scattering of light. Pearlescent effect pigments present color through the interference effect of multiple layers.

And PNM, with its independently developed technology, has broken the limitations of traditional pigments, producing the fourth type of pigment on the pigment manufacturing technology platform – ‘Preamber’ lucid pearlescent effect pigment.

‘Preamber’ lucid pearlescent effect pigments do not add any colorants, but are based on the unique physical properties of photonic crystal structures. This structural color effect is produced through the interference and reflection of light in nanoscale structures, with the formation of colors entirely dependent on the arrangement of microspheres within the material. Therefore, ‘Preamber’ exhibits more pure color performance, possessing characteristics of transparency, high chroma, high brightness, and high sparkle, which enable it to present different color visual effects under different viewing angles.

Meanwhile, the background color also has an impact on the visual performance of ‘Preamber’ lucid pearlescent effect pigment:

1. In transparent carriers

The color performance of ‘Preamber’ lucid pearlescent effect pigments is relatively mild, mainly displaying iridescent effects. This effect gives the material a refined color change, suitable for product applications that require subtle visual effects.
It can be used with dyestuffs together, final product will have dye color and pearl effect at the same time, which is not possible by traditional pearl pigment.

2. In white carriers
The transmitted light interferes with the reflected light from the photonic crystal, creating a unique pearlescent effect. This effect makes ‘Preamber’ lucid pearlescent effect pigment exhibit richer and softer colors in applications, suitable for various decorative uses.

3. In black carriers
A black background can absorb all transmitted light, and to the naked eye, it shows strong reflective colors from the photonic crystal. This reflective color has significant angular dependence, changing with the viewing angle and displaying a dynamic visual effect.

PART 02  Application

‘Preamber’ not only offers extremely high flexibility in color performance, but also has stable weather resistance and environmental characteristics. It can adapt to various scenarios, and its excellent optical properties are currently widely used in coatings, plastics, and adhesive films. Whether it is showcasing highly artistic fashion items or adding higher value to industrial designs, ‘Preamber’ can meet the market’s demand for high-quality, high-performance pigments.

‘Preamber’ represents a new height in the application of photonic crystal materials, and LightDrive Technology will continue to bring more diverse and varied color options to different industries through its proprietary research and development processes.
