ABSTRACT:
Disclosed is a release material applied to a sheet material that provides for temporary repositioning of an adhesive over the release material. Over time the adhesion between the release material and the applied adhesive builds such that the adhesive cannot be removed from the release material without damaging the underlying sheet material. The release material includes an free nitrogen containing basic group. The release material is dispersed on a flexible substrate and the release material allows for repositioning when contacted with a pressure sensitive adhesive, which includes a free carboxylic acid group, for at least 1 minute and not more than 10 minutes.
