Abstract: A composite material and method for forming graphics such as letters or numbers that are pressure transferable to a substrate. The composite material includes an accepting tape including a layer of latent adhesive material on a receiving web, and a friable slightly adhesive layer lightly adhered to a donor web. When the layers are pressed together and the composite material is selectively heated in graphic patterns, corresponding portions of the adhesive material and friable layer adhere together so that upon subsequent separation of the layer of adhesive and the donor web portions of the friable layer transfer to the accepting tape in the heated areas to provide graphics. When the graphics are then positioned against a substrate and are pressed against the substrate by rubbing pressure applied through the receiving web, the adhesive layer will tear around the graphic and separate from the receiving web over the graphic so that the graphic will be transferred to the substrate.

Abstract: The present invention involves compositions of super absorbent polymers which absorb many times their weight in water and aqueous fluids. Super absorbent polymers in the prior art have effectively absorbed many times their weight of water, however, they become slimy to the touch or become so fluid as to migrate away from their point of application.The absorbent composition of the current invention absorbs substantial amounts of water without becoming slimy and migrating out from its applicator, as in absorbent articles. The absorbent composition of the current invention comprises a copolymer of acrylic acid cross-linked with a first cross-linking component comprising a monomer having at least two vinyl groups and a second cross-linking component comprising an ionic divalent cation. In the current invention, this composition can be mixed with cellulose fibers to enhance wicking.

The coating consists essentially of a thermosetting resin vehicle and a high molecular weight, hard, paraffin wax which, when cured, at a temperature greater than the melting point of said wax provides a reduced surface contact area of lubricating beads high in wax content.

Abstract: A composite material for forming graphics such as letters or numbers. The composite material includes a layer of latent adhesive material, a mono-layer of granules lightly adhered to a donor web, and a thin layer of bonding material between and in face-to-face contact with the layers of granules and adhesive. The layer of bonding material maintains the adhesive and granular layers in close proximity and excludes air from therebetween. When the composite material is selectively heated in graphic patterns, corresponding portions of the bonding layer melt; and corresponding portions of the adhesive material and granular layer soften, absorb the melted portions of the bonding layer and adhere together. Upon subsequent separation of the layer of adhesive and the donor web the remaining portions of the layer of bonding material separate, whereas granules transfer to the accepting tape in the heated areas to provide the graphics.

Abstract: Elastomeric particles, e.g., rubber grindings and buffings produced in vehicular tire manufacturing and recapping operations, are incorporated into at least one surface of particle-board panel to increase friction, prevent stacked panels from sliding in echelon, prevent tools from sliding thereon, prevent workmen from slipping thereon, and still allow the panel to be cut and nailed. The particles can be bonded to the panels simultaneously with the panel molding operation or in a separate subsequent operation. In a preferred method of fabricating a non-skid construction panel of the subject invention, rubber particles in the range from below about 10 to above about 20 pounds per one thousand square feet of surface area are distributed over a panel, and the rubber particles and the panels are subsequently subjected to heat and pressure, and the resulting panel has a smooth surface with the elastomeric particles being used somewhat as a light "salting" of the construction panel's surface layer.

Abstract: The appearance of simulated textured metal is imparted to a surface, which may comprise part of a design, by mixing a tinted aqueous solution of dextrin with a polyvinyl acetate emulsion to form a liquid base material. This base material is applied to the surface and thereafter a coating comprising a mixture of borax and a metal in powder form is distributed over the uncured base material. As the polyvinyl acetate dries a textured finish which simulates textured metal is obtained.

Abstract: An improvement in the process for producing a decorative surface covering having a multilevel embossed wear surface wherein, a layer of vinyl chloride resin dryblend which may be foamable or unfoamable, and which contains a polymerizable monomer having at least two olefinically unsaturated sites is formed.

The improvement of this invention comprises the inclusion in the plurality of inks printed in a design on the monomer-containing dryblend layer of an ink containing the same polymerizable monomer as that in the dryblend, and a catalyst for the monomer.
