Abstract
A pressure sensitive adhesive composition comprised of: a) 75 to 99.9 weight percent of a tackified thermoplastic polymer component comprising 1) 1–99 weight percent of a thermoplastic polymer substantially without epoxy-binding or ester functions, and 2) 1–99 weight percent of a tackifier; and b) 0.1 to 25 weight percent of an epoxy component comprising a cured epoxy and non-woven webs made of this adhesive composition.
