ABSTRACT:
The present invention discloses a novel readily removable and repositionable pressure-sensitive adhesive composition especially suitable for thin adhesive film applications to the surface of paper or other laminar backing materials, for easy application and removal of the laminar backing to a variety of substrate surfaces, which comprises: (1) a carboxyl-modified vinyl chloride-vinyl acetate copolymer; (2) a polymeric polyester plasticizer; and (3) a halo-organophosphorous plasticizer. In the present novel repositionable pressure-sensitive adhesive composition, the desired tack or adhesive bonding strength is selectively controlled by adjusting the relative concentration ratios of the halo-organophosphorous plasticizer and the polyester plasticizer in combination with the vinyl chloride-vinyl acetate copolymer.
