Abstract: PROBLEM TO BE SOLVED: To obtain an open-cell foam exhibiting decreased oil and water absorption by coating the whole or a part of the surface of a resin having a cellular structure with a fluoroalkyl ester. SOLUTION: Preferably, an amount of a fluoroalkyl ester applied is 0.001-5 mass %, and the fluoroalkyl ester is preferably a completely fluorinated one. Preferably, the fluoroalkyl ester is a completely fluorinated 1-10C alkyl ester of acrylic acid, methacrylic acid, polyacrylic acid, polymethacrylic acid, phosphoric acid, or a 1-6C fatty acid. The objective foam is prepared by immersing a melamine resin foam in a milky aqueous solution of a fluoroalkyl ester or spraying the solution into the foam, then squeezing the foam to remove an excess of the solution, and drying the foam at 40-200 deg.C. The concentration of the milky solution used is preferably 0.1-20 mass %.

Abstract: The invention relates to magnetic recording media, consisting of a nonmagnetic substrate and at least one magnetisable layer firmly applied thereon and based on a polyurethane binder which is optionally crosslinked with polyisocyanate, the binder consisting of at least 50% by weight of a low molecular weight branched polyureaurethane having OH-containing groups at the chain ends, and in which the sliding properties are improved and the friction is reduced by incorporating siloxanes.

Abstract: A magnetic recording material is produced by spreading a dispersion of anisotropic material particles together with other particles in a fluid solution over the surface of a corner. The solution consists of a polymer binding agent in an organic fluid. The material is passed through a magnetic field to orientate the magnetic particles. The mixture has carbon in a water repellent polysilicic acid in 0.3 to 5 percent by weight. ADVANTAGE - Avoids high wear resistant over wide temperature range.

Abstract: Layer-type magnetic recording media are produced by dispersing a finely divided magnetically anisotropic material in a binder which consists of not less than 40% of a radiation-curable aqueous binder dispersion, applying the dispersion onto a non-magnetic base, orienting the magnetically anisotropic material and drying and crosslinking the applied layer by means of UV or high-energy electron radiation.

Abstract: A process for the production of coatings based on reaction products of (A) polyhydroxypolyacrylate resins obtained from hydroxyalkyl esters of acrylic acid and/or methacrylic acid, alkyl esters of acrylic acid and/or methacrylic acid, and one or more polymerizable, olefinically unsaturated nitrogen-containing heterocyclic compounds, with or without vinylaromatics, (meth)acrylamides and other monomers, with (B) isocyanurate-containing polyisocyanates which may or may not contain biuret groups, have a functionality of from 2.5 to 6 and consist of a mixture of polyisocyanates possessing predominantly cycloaliphatically bonded isocyanate groups with those possessing predominantly aliphatically bonded isocyanate groups. The process is particularly useful for coating metal components.
