Abstract
Abstract METALLIZING COATING COMPOSITIONS HAVING GREATER SPARKLE AND GLITTER ARE FORMED BY INCLUDING IN THE COATING COMPOSITION INSOLUBLE RESIN-SUPPORTED PLANAR REFLECTIVE METAL FLAKES IN AN AMOUNT OF FROM ABOUT 0.003% TO ABOUT 0.035% OF METAL (PARTICULARLY ALUMINUM) BASED ON THE WEIGHT OF THE COMPOSITION. THE FLAKES ARE SUPPORTED AND RENDERED MORE PLANAR BY USING A METAL FILM SURFACED ON BOTH SIDES WITH A RELATIVELY INSOLUBLE RESINOUS FILM HAVING A THICKNESS OF AT LEAST 0.01 MIL. WHEN THE SUPPORTED METAL FILM IS BROKEN UP TO FORM FLAKES, THE FLAKES ARE FLATTER AND REFLECT LIGHT OVER A LARGER PORTION OF THEIR SURFACE TO PERMIT USE IN SMALLER AMOUNT.
