    摘要: An antistatic composition is provided for use with a label construction which includes an organic cationic polyelectrolyte, a binder, and a surfactant. The composition is preferably used in a label construction comprising a polymer film substrate having a pressure sensitive adhesive on its second surface, a release liner overlying the pressure sensitive adhesive, with the antistatic composition being provided on the second surface of release liner. The antistatic composition reduces the surface resistivity of the second surface of said release liner. The antistatic composition may also be used in combination with a toner adhesion-enhancing coating which is provided on the first surface of the substrate to improve print quality. The labels may be stacked or provided in roll form such that the antistatic composition reduces the coefficient of friction between adjacent labels and prevents the build-up of static charges on the labels.

    摘要: Pressure-sensitive adhesive material comprising a backing member, a pressure-sensitive adhesive on the front side thereof, and a release coat on the backside thereof comprising poly(amide acids), e.g., poly(N-fatty alkyl amide-acids) of the following recurring formula:

    WHEREIN A is a divalent organic radical containing from 2 to 15, preferably 2 to 6, carbon atoms, B is a tetravalent organic radical containing at least 4 carbon atoms, R1 is hydrogen or an alkyl radical containing about 1 to 30 carbon atoms and R2 is an alkyl radical containing about 12 to 30 carbon atoms. When R1 is hydrogen, also provided are the corresponding cyclized imide products and mixtures of the polyamides and polyimides. These poly(amide acids) are formed by the reaction of tetracarboxylic acid dianhydrides and fatty diamines.
