摘要

the invention relates to a gieu00dfmasse containing ceramic powder, binder and dispersionsmedium, which is suitable for foliengieu00dfverfahren green keramikfolien manufacture.it contains a dispersionsmedium essentially water and as a binder a emulsionscopolymerisat, 95 to 75 wt.% esters of acrylic and / or methacrylic acid and 5 to 25% by weight.-%, ethylenisch unsaturated carboxylic acids is established in an amount of 2.0 to 10 wt. -%, relative to the total weight of the gieu00dfmasse.the said emulsionscopolymerisat erfindungsgemu00e4u00df is in the form of microspheres with a mean particle size, expressed as a gewichtsmittel dw, in the range of 75 to 150 nm.
