Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
185 words
A printable high-adhesion pressure-sensitive adhesive tape comprising a backing film or foil which is coated on one side with a high-adhesion pressure-sensitive adhesive of an elastomer and tackifier resin wherein in said adhesive, the major portion of the elastomer is of an A-B-A or A-B block copolymer wherein A is a thermoplastic polymer block derived from a vinylarene and B is an elastomeric polymer block derived from a conjugated diene and which is coated on the other side with a release coating comprising (1) from about 85 to 15 parts by weight of a vinylidene chloride-acrylonitrile copolymer, (2) correspondingly from about 15 to 85 parts by weight a polymer selected from the group consisting of a vinyl chloride-vintl acetate-vinyl alcohol terpolymer, a vinyl acetate-vinyl alcohol copolymer, and a solvent-soluble copolyester, and (3) for every 100 parts of (1) and (2), from about 17.5 to 55 parts by weight of a copolymer of vinyl ester and alkyl maleate wherein the alkyl group has a chain length of at least about 16 carbon atoms, said release coating being ink-imprintable and low-force removable from said high-adhesion pressure-sensitive adhesive.
Claim 2
Dependent Claim
