Abstract The present invention relates to release coatings which comprise cellulosic esters or cellulosic ethers in combination with adhesion-promoting compounds having an affinity for vinyl chloride-containing com- positions. The release coatings maintain their adherence characteristics during processing of the structure in which they are disposed, but substantially lose their adherence characteristics when said structure is fused, thereby becoming easily separable from the resulting product.
