, a principle:
coercive color color photosensitive materials by the sun / TestDaF after UV irradiation, resulting in color change; when sunlight / UV will revert back to the original color.

Two, the basic 4 color: purple, red, blue, yellow. (colorless colored)

Intermateable between three, basic color

Four, color photosensitive materials can have a lot of use:

The material: color photosensitive pigment adding ratio of 10-30%, suitable for all kinds of surface coated products, including PMMA, ABS, PVC paint spray paint and water-based paint etc.;

Oil ink: color photosensitive pigment adding ratio of 20-40%, suitable for all kinds of printing materials, including fabric, paper, synthetic membrane, glass etc.;

Plastic products: color photosensitive pigment adding ratio of 0.8-3%, suitable for all kinds of plastic injection, extrusion molding, products have a high concentration of color masterbatch and photosensitive photosensitive PE PMMA Color Masterbatch products.

Five, dosage

For injection molding, extrusion molding, casting, machining or curing, pigment dosage amount of plastic 0.4~3.0%, usually 0.6 ~2.0%. The pigment and plastic particles to fully mix (mixed can use a small amount of white oil). If it is a common color and the color of the color, then the amount of ordinary pigments (or dyes) about the color of the 0.5-2.5%.
