| abstract |
The invention relates to a noble metal preparation for the production of noble metal decorations on substrates which may be decoratively glazed, by means of direct printing and indirect printing (transfer methodology). The print quality of the preparation, containing the noble metal compounds and a binding agent system, on highly curved glass may be improved where transfer methodology is used, whereby the binding agent system comprises a resin mixture of (a) 25 to 50 wt. % of polyamide resins, (b) 5 to 30 wt. % of sulphurised recent resin, (c) 10 to less than 20 wt. % of rosin-modified resins, (d) 10 to 40 wt. % of alkylphenol resins and (e) 0 to 30 wt. % of other compatible resins, whereby two or more components of said resin mixture are in the form of a reaction product formed at 50 to 150 DEG C, or/and one or more components of said resin system or reaction products can themselves be present in the form of a reaction product, formed at 50 to 150 DEG C in the presence of a sulphur-containing gelling agent and the noble metal compounds. |
