  • Method of improving an adhesive article
    Patent number: 6235344
    Abstract: A method of improving an adhesive article, such tape, a label or repositionable paper, containing a paper facestock layer and an adhesive layer is disclosed. The adhesive layer contains a pressure sensitive adhesive and voided latex particles. The incorporation of the voided latex particles into the adhesive layer provides opacity and improves shear strength, without unacceptably compromising the tack and peel adhesion properties of the adhesive layer and without causing wear to processing equipment relative to conventional fillers.
