Process for activating substrates for electroless metallisation A b s t r a c t Complex compounds of elements of sub-groups 1 and 8 of the periodic table in oxidation stages 1-4 with un- saturated ketones of the formula (I) Image wherein R1 and R4 denote alkyl, cycloalkyl or aryl and R2 and R3 denote hydrogen or alkyl, are outstandingly suitable for activating substrate sur- faces for electroless metallisation since these complexes are distinguished by a high storage stability. The pal- ladium complexes of but-3-en-2-one and hept-3-en-2-one are preferred.
