The present invention relates to an aqueous coating composition. The aqueous coating composition comprises (a) a polymer A comprising units derived from an alpha-olefin and one or more comonomers selected from the group of methacrylates, acrylates, methacrylic acid, acrylic acid, maleates, maleic acid, maleic anhydride, and salts thereof; (b) a polymer B comprising units derived from one or more monomers selected from the group of methacrylates, acrylates, methacrylic acid, acrylic acid, maleates, maleic acid, maleic anhydride, and salts thereof; (c) a calcium carbonate-containing material in an amount in the range of 0.1 to below 20 wt. %, based on the total dry weight of the coating composition; and (d) optionally a wax. Furthermore, the invention relates to a process for preparing an aqueous coating composition according to invention, and to a coated article.

The present wax coating compositions are based on the use of n-alpha olefins instead of petroleum-based paraffin waxes otherwise currently employed. The coating composition may be used with various coating techniques, however, the compositions herein are found useful especially in curtain coating, cascading, saturating or impregnating technologies. Other coating techniques include roll coating or the use of coating or Meyer rods.

A composition for use as an assay reagent includes a paramagnetic solid support comprising a coating of a synthetic copolymer. The synthetic copolymer comprises two or three of a first copolymerized monomer, a second copolymerized monomer and a third copolymerized monomer and further comprises a polyethylenic backbone.

The present invention relates to a thermally conductive polymer composition. The thermally conductive polymer composition comprises (a) 30 to 60 parts by weight of a polymer, and (b) 100 parts by weight of a boron nitride filler comprising, (b-1) 70 to 99 parts by weight of a spherical boron nitride filler, and (b-2) 1 to 30 parts by weight of a sheet boron nitride filler having a thickness of 5 to 500 nm, a surface area of 4 to 50 m.sup.2/g and an aspect ratio of 100:1 to 10000:1.

Disclosed herein is an electrically conductive adhesive composition and its use in solar cell modules, wherein the electrically conductive adhesive comprises a polymer matrix and dispersed in the polymer matrix about 40-90 wt % of conductive particles, with the wt % of all components comprised in the compositions totaling to 100 wt %, and wherein the polymer matrix comprises or is formed of a blend of at least one ethylene/alkyl (meth)acrylate copolymer elastomer and at least one ethylene vinyl acetate copolymer at a weight ratio ranging from about 10:90 to about 70:30.

The present invention consists of a process of preparation of at least one mineral matter and/or of at least one pigment, including a calcium carbonate made at once partially organophilic and partially hydrophilic, in which the carbonate is blended and/or ground and/or concentrated in an aqueous medium, in the presence of at least one salt of ethylene acrylic acid, one dispersing agent and/or one grinding aid agent, which is introduced before and/or during this treatment stage. Another object of the invention lies in the aqueous dispersions and suspensions of calcium carbonate thus obtained. They may be dried and the dry pigments obtained also constitute an object of the invention. Use of these aqueous dispersions and these dry pigments in the field of plastic, paints and paper constitutes another object of the invention.
