    摘要: The invention relates to a noble metal preparation for the production of noble metal decorations on firable decoration substrates by direct printing and indirect printing (decalcomania method).The print quality of the noble metal compounds and preparations containing a binder system on markedly curved glass may be improved when the decalcomania method is used in that the binder system consists of a resin mixture comprising (a) 25 to 50 wt. % of polyamide resins, (b) 5 to 30 wt. % of sulphurized recent resins, (c) 10 to less than 20 wt. % of colophony-modified resins, (d) 10 to 40 wt. % of alkyl phenolic resins and (e) 0 to 30 wt. % of other resins compatible therewith, wherein two or more components of said resin mixture may be present in the form of a reaction product formed at 50 to 150° C. and/or wherein one or more components of said resin system or reaction product thereof may be present in the form of a reaction product formed at 50 to 150° C. in the presence of a sulphur-containing gelation agent and the noble metal compounds.
