Radiation curable precious metal preparation, transfers containing same and method for decoration

A precious metal preparation capable of radiation curing, comprising:

• a. one or more precious metals from among gold, silver, platinum and palladium in elementary and/or alloyed form and/or in the form of a compound,
• b. one or more fluxes from among compounds of Mg, Al, K, Na, Ca, Bi, Si, Ti, V, Cr, Mn, Fe, Co, Ni, Cu, Zn, Zr, Rh, Ru, Sn, In, Sb, Pb and Bi,
• c. a printing medium capable of radiation curing, and
• d. at least one organic compound in particle form which is insoluble and incapable of swelling in the printing medium and burns substantially completely in decoration firing,
• e. wherein the at least one organic compound is a medium for increasing the pigment volume concentration.

The precious metal preparation of 9 containing:

• a. 10 to 50% by weight of gold in elementary form,
• b. 0.1 to 20% by weight of flux,
• c. 1 to 10% by weight of medium for increasing the pigment volume concentration, and
• d. 30 to 80% by weight of a medium capable of radiation curing, wherein the medium capable of radiation curing comprises a polymer dissolved in a photo-polymerizable monomer and a photo-initiator in an amount of 0.1 to 20% by weight, based on the weight of the medium capable of radiation curing.
