Abstract
Abstract This invention concerns a process of forming an aesthetically pleasing random pattern on the surface of a substrate comprising the steps of coating the surface with a retractable liquid, the retractable liquid having a surface tension that is at least about 2 dynes/centimeter above the critical surface tension of wetting of the surface and also concerns the articles produced by this process.
