Abstract

The present invention relates to an adhesive coated mounting substrate with a clear plastic cover sheet that may be used for mounting and displaying relatively flat items. These mounting substrates are especially useful as pages in photograph albums. The novel advantage of the mounting substrate of the present invention is accomplished by coating the substrate with an adhesive which includes an aliphatic alkene glycol in its liquid phase and an aliphatic acrylate elastomer in its solid phase. A particularly suited use for the coated mounting substrate of the present invention is in the photographic album page art. The solid phase of the adhesive used in the production of the coated substrate of the present invention is comprised of an aliphitic alkene elastomer and an inorganic filler. The liquid phase is comprised of an aliphatic alkene glycol, water and an inorganic hydroxide pH adjuster. When the coated substrate of the present invention is used in photographic album pages, many of the disadvantages inherent in the present day latex-based photographic album pages are overcome, for example, page discoloration, photograph damaging, loss of adhesiveness after a period of time and blocking, is eliminated. Blocking is a term of the photographic album page art that indicates a phenomenon that occurs when a permanent bond between the photograph and the substrate, takes place.
