Abstract

The invention relates to a ceramic color paste, in particular a color paste containing alkyd resins, for the production of decorations on surfaces of glass, porcelain or ceramic, and a printing medium for the preparation of the color paste. Known generic color pastes and printing media for producing the same generally have an intense odor and tend to form a skin if an alkyd resin is present. The invention overcomes these disadvantages by the solvent system of the printing medium of the color paste containing substantially at least 50 to 100% by weight, preferably above 70% by weight, of one or more isoparaffins and from 0 to 50% by weight, preferably from 0 to 30% by weight, of one or more solvating plasticisers. Skin formation is prevented by the presence of an aldoxime or ketoxime containing 3 to 6 carbon atoms or an anti-oxidant for polymer systems.
