| Zusammenfassung: | The present invention is generally directed to adhesives and more specifically to pressure sensitive adhesives such as are used in self-adhesive labels and tapes. Pressure sensitive adhesives include general purpose pressure sensitive adhesives and removable pressure sensitive adhesives and typically comprise styrene-butadiene rubber (SBR) or acrylic copolymers. In particular, the invention is directed to the use of starches including enzyme thinned starches in combination with styrene-butadiene rubber or acrylic copolymers as components of pressure sensitive adhesives.
Pressure sensitive adhesive compositions comprising (a) a synthetic polymer latex; and (b) an aqueous dispersion of thinned, derivatized starch are disclosed. |
