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 0.0003 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. The present invention relates to organic coatings containing separated reflective aluminum flakes which add sparkle to the coated film.
Claims13
A coated substrate comprising a base coated with a continuous film having resin-supported planar metal flakes dispersed therein, said flakes having a planar dimension in excess of 30 microns up to about 200 microns and providing less than 100 reflecting flakes per 5.5 square millimeters of surface area.
A coated substrate comprising a base coated with a continuous film having resin-supported planar metal flakes dispersed therein, said flakes having a planar dimension in excess of 30 microns up to about 200 microns and providing less than 100 reflecting flakes per 5.5 square millimeters of surface area, and said film containing from 0.00102 percent to 0.1193 percent metal.
A coated substrate comprising a base coated with a continuous film having resin-supported planar metal flakes dispersed therein, said flakes having a planar dimension in excess of 30 microns up to about 200 microns, and said film containing from 0.00102 percent to about 0.1193 percent metal.
A coated substrate comprising a base coated with a continuous film having resin-supported planar metal flakes having a thickness of up to about 25 millionths of an inch dispersed therein, said flakes having a planar dimension in excess of 30 microns up to about 200 microns, and providing spaced apart flakes in the film which are able to reflect light over a relatively substantial surface area of the flake to provide a pronounced glitter.
