Abstract
Polyketone resins are used as an ingredient of the release coating for a flexible pressure-sensitive tape. The release coatings are printable and at the same time remain effective as release agents due to the presence of the polyketone resins. The polyketone resins are blended with a monomeric or polymeric release agent and an elastomeric or resinous film former to give the improved properties.
Claims5
A pressure-sensitive adhesive tape comprising a backing of paper, cloth, film, or foil material, a pressure-sensitive adhesive applied to one side of said backing, and a release coating composition applied to the other side of said backing, the release coating composition being a blend of about 10-30 parts by weight of an organic release agent, about 20-70 parts of a film former, and from 15-40 parts of a polyketone resin to provide printability.
