Abstract

Solutions of accelerator systems comprising a binary system comprising PA0 a) 10 to 90% by weight of a salt of formula I EQU [Me].sub.m.sup.x.sym. [R].sub.n.sup.y.crclbar. (I), PA1 wherein x and y are the respective number of charges and m and n are each a number 1, 2, 3 or 4, Me is a metal atom and R is the radical of an alcohol, phenol or thiophenol or of a carboxylic acid or thiocarboxylic acid, or PA1 10 to 90% by weight of a salt of formula II EQU [Me.sub.1 ].sub.m.sup.x.sym. [A].sub.n.sup.y.crclbar. (II), PA1 with an organic complex former containing one or more hetero atoms having free electron pairs, PA1 wherein Me.sub.1 is a metal atom or a group of the formula N(R.sub.1).sub.4, S(R.sub.1).sub.3 or P(R.sub.1).sub.4 wherein each R.sub.1 independently of the others is hydrogen, an unsubstituted or substituted C.sub.1 -C.sub.6 alkyl or aryl radical, A is any anion and x, y, m and n are as defined above, and PA0 b) 90 to 10% by weight of an organic solvent containing at least one --OH, --OR.sub.1, --COOH, --COOR.sub.1, --COR.sub.1 or --CON(R.sub.1).sub.2 group wherein R.sub.1 is hydrogen, an unsubstituted or substituted C.sub.1 -C.sub.6 alkyl or aryl radical, are storage-stabl…
