Abstract
Abstract Pressure-sensitive adhesive tapes having solvent resistant adhesive coatings which consist essentially of an epihalohydrin polymer and a thermoplastic polyketone resin comprising the condensation product of an aliphatic ketone having a total of 3 to 6 carbon atoms; a monoaryl alkyl ketone having from 6 to 10 ring carbon atoms in the aryl group and from 1 to 4 carbon atoms in the alkyl group; an aliphatic ketone having a total of 3 to 6 carbon atoms with a lower aliphatic aldehyde; a monoaryl alkyl ketone having from 6 to 10 ring carbon atoms in the aryl group and from 1 to 4 carbon atoms in the alkyl group with a lower aliphatic aldehyde; or a carbocyclic ketone having 3 to 7 ring carbon atoms with a lower aliphatic aldehyde.
