Abstract: A transfer adhesive sandwich includes a flexible carrier sheet having an adhesive layer releasably bonded to one surface and having an opposite surface to which the adhesive layer is releasably bondable with substantially less tenacity than the tenacity of the bond between the adhesive layer and the one surface. A plurality of the sandwiches are stacked on top of one another to form a pad from which individual sandwiches are strippable. When the adhesive layer is pressed against a substrate, it adheres to the substrate with a tenacity substantially greater than the tenacity of the bond between the adhesive layer and the one surface of the carrier sheet so that the carrier sheet can be stripped away to leave the adhesive layer on the substrate.

The predetermined shapes of the subdivided panels may be any desired shape--rectangular, square, triangular, trapezoidal, a parallelogram, circular, etc.

Abstract: A canvas for use by an artist for painting includes a flexible substrate material having a surface coating of a refined animal glue which forms a translucent glaze as the painting surface. The substrate is preferably open-weave nylon having a denier value of between 200 and 400 denier, inclusive. A binding intermediate coating of either rabbit skin glue or a whitener may be used to increase the binding of the surface coating to the substrate, and the coated substrate may be mounted on a stretching framework and, if desired, backed by butcher's paper. The production process for this canvas includes the steps of coating a sheet of the substrate with a binding material, drying this first coat, glazing the material with a glazing compound that dries to a translucent layer, and drying the glazed sheet. This process may be a continuous stream production process.
