Plastics processors serving markets as various as cosmetic packaging, appliances, and sporting goods can achieve iridescent multi-colored effects through the use of Teknor Color Co.'s new Magic Color concentrates with Variocrom pigments from BASF. The pigments generate a play of bright colors that shift or merge from one into another as the viewing angle changes adding a whole new dimension of consumer appeal. Available colors in the Magic Color Concentrate series include red, green, gold, purple, violet, blue autumn, purple-green, and green-gold, with other colors available upon request. The intensity of the color-variable effect depends on the clarity of the natural resin used, and the shift in hue is most pronounced in large parts with multiple curves. Possibilities range from dramatic color shifts, such as from rose to green, to many kinds of subtle effects. For example, a part might be transparent when viewed at an angle of 90 degrees, colored at 15 degrees, and opaque at 180 degrees applications.
