ABSTRACT:
A hot melt process for producing a release coating. The process involves first forming a mixture of a release agent and a thermoplastic polymer in the absence of a solvent. The release agent is not completely compatible with the thermoplastic polymer. The mixture has a softening temperature ranging from about 120.degree. to about 350.degree. F. The mixture is heated to a temperature at or above its softening temperature and then coated onto at least a portion of a substrate. The coated substrate is cooled for a time and at a temperature sufficient to cause the mixture to solidify.
