Abstract: Various shaped abrasive particles are disclosed. Each shaped abrasive particle includes a body having at least one major surface and a side surface extending from the major surface.

Abstract: A method for forming a heat sealable coating on a substrate, wherein the substrate is formed from at least one oriented polymer is shown. The method includes depositing an aqueous polymer dispersion on the substrate, wherein the aqueous polymer dispersion includes (A) at least one thermoplastic resin; (B) at least one dispersing agent; and (C) water; wherein the dispersion has a pH of less than 12, and drying the dispersion to form a first layer.

Abstract: An emulsion polymerized latex composition suitable for use as a pressure sensitive adhesive having from about 90 to about 99.5 percent by total weight polymer of sec-butyl acrylate and from about 10 to about 0.5 percent by total weight polymer prepared from monomers selected from the group consisting of alkyl esters of acrylic and methacrylic acids wherein the alkyl chain has up to about 20 carbon atoms, monovinylidene aromatics, and ethylenically unsaturated carboxylic acids. Additionally the latex composition can include from about 1 to about 90 percent by weight on a total solids basis of a tackifying resin. Adhesives prepared with the subject latex compositions provide an excellent balance of adhesive properties, i.e., peel and shear adhesion.

Abstract: Precipitation at relatively high pH levels, e.g. above about 4 or more, in an acidic water/alcohol type fountain composition containing polyvalent metal cations and, as an active polymer component for rendering the non-image areas of a lithographic plate hydrophilic, a polyacrylamide-based polymer having a weight average molecular weight (M.sub.w) of from about 5,000 to about 1,000,000 and having from about 3 to about 70 percent of the carbonyl sites as carboxyl groups, or a blend of polyacrylamide and polyacrylic acid, or the like, is controlled by providing in the fountain composition an effective amount of an organic chelating agent for polyvalent metal cations which is substantially inert with respect to the active polymer component. The suitable chelating agents are further characterized in that at 25.degree. C, each (A) has a 1:1 stability constant with zinc of at least about 10.sup.7.5 ; (B) has a solubility of at least about 0.

Abstract: Photoconductive compositions containing aromatic sulfonyl fluorides are novel compositions which are useful in electrophotographic processes, such as xerography. E.g., an electrostatic copying paper is obtained by coating an electroconductive base paper with a composition comprising poly(N-vinylcarbazole) and 4,4'-biphenyldisulfonyl fluoride.
