Abstract
There is disclosed an aqueous-base coating composition containing, as essential components, finely-divided, water-dispersable: colorant, polyethylene, binder and water with sufficient of a surface active agent to form a stable suspension. The coating composition is applied as a film coating onto a polyethylene surface and the binder temporarily binds the coating to the surface until the coating can be thermally treated to incorporate the coating into the polyethylene, permanently coloring the surface. The invention also comprises a method for the preparation of the aqueous-base coating composition in which the essential components are prepared as aqueous dispersions or emulsions which are blended together to form the final coating composition.
