Abstract
Abstract A binder loose leaf for mounting photographs or the like. It is made up of a flat base having a pressure-sensitive non-drying adhesive composition coated over one of its face and an air-protection film applied over the adhesive composition. This film can easily be removed by light rubbing friction to expose the adhesive composition when it is desired to fix a photograph or the like on the loose leaf.
