Abstract
An aqueous composition that can be used to provide a release release properties to adhesive tape substrates can be applied at coating weights far less than those required in previously available compositions containing the same or similar release polymers. Inclusion of small amounts of a superwetter results in improved coatability and reduced amounts of sound generated during the process of releasing an adhesive tape from its roll.
