Abstract
Aqueous release coating compositions for application to substrates having low absorption thereinto, excellent adhesion thereto, and easy and quick release and removal therefrom comprising: from about 3% to about 8% of polyvinyl alcohol; from about 9% to about 35% clay; from about 5% to about 12% of an adhesive binder; and from about 49% to about 75% of water. All percentages being by weight, based on the total weight of the aqueous release coating composition. The resulting release-coated substrates are also included in the inventive concept.
Claims7
A release composition-coated material capable of having other materials applied and adhered thereto and of having said other materials subsequently easily and quickly released and removed therefrom comprising:
- a substrate in sheet material form:
- and a release coating composition on said substrate comprising from about 3 parts to about 8 parts of polyvinyl alcohol:
- from about 9 parts to about 35 parts of clay:
- having a particle size of from 0.25 to about 4 microns and from about 5 parts to about 12 parts of an adhesive binder, all parts being by weight:
- and a layer of polyvinyl chloride sheet material adhered to said substrate by said release coating composition but being subsequently easily and quickly released and removed therefrom.
