摘要： Conventional coating compositions prepared by compounding an aqueous solution of an inorganic component (mainly comprising chromic acid) with an aqueous emulsion of an organic component (comprising a polymer) are disadvantageous in that their pot life is short, they are so highly foaming that foams are apt to occur in the coating, the coating has inferior corrosion resistance and insulation performance, a gas is generated from the coating during welding to result in poor weldability, and a composition further containing an acrylic resin to eliminate these disadvantages is highly carburizable. The coating composition of the invention comprises an aqueous dispersion of a (meth)acrylate polymer, which has been used heretofore as the organic component, modified with an ethylenically unsaturated carboxylic acid as the essential comonomer component and other vinyl compound(s) as the optional comonomer component, or further an aqueous dispersion prepared by adding a powdered methacrylate polymer to the above modified polymer. These compositions are lowly foaming and excellent in applicability, and give a coating excellent in various properties. Especially the composition containing the powdered methacrylate polymer is so excellent in weldability, that it can meet the recent demands on the diversified and high-quality products of electric sheets.
摘要翻译：通过将无机组分（主要包含铬酸）的水溶液与有机组分（包含聚合物）的水性乳液混合制备的常规涂料组合物的缺点在于它们的适用期短，它们的泡沫如此高度起泡，易于发生在涂层中，涂层具有差的耐腐蚀性和绝缘性能，在焊接期间从涂层产生气体，导致不良的焊接性，并且进一步含有丙烯酸树脂以消除这些缺点的组合物是高度可渗碳的。本发明的涂料组合物包含（甲基）丙烯酸酯聚合物的水分散体，其已被用作有机组分，用烯键式不饱和羧酸作为必要的共聚单体组分和其它乙烯基化合物作为任选的共聚单体组分，或另外通过向上述改性聚合物中加入粉状甲基丙烯酸酯聚合物制备的水性分散体。这些组合物发泡性低，适用性优异，得到各种性能优异的涂膜。特别是含有粉末状甲基丙烯酸酯聚合物的组合物的焊接性优异，能够满足电工板材多样化，高质量产品的近期需求。

摘要： [Problem] To provide a mold release film for the production of a ceramic green sheet, which maintains high smoothness of the surface of a mold release layer, and which is free from the possibility of damaging a ceramic green sheet when the ceramic green sheet is removed from the mold release layer even in cases where the ceramic green sheet is an ultrathin layer material having a thickness of 1 μm or less by having the force applied to the ceramic green sheet during the removal from the mold release film low and uniform. [Solution] A mold release film for the production of a ceramic green sheet, which is obtained by providing a mold release layer on a surface layer A of a polyester film, said surface layer A substantially containing no inorganic particles, and which is configured such that the mold release layer is obtained by curing a composition that contains a binder a which contains cationically curable substance and one or more mold release agents b.
