Claim 1
Independent Claim
225 words
A liquid composition consisting essentially of: (a) at least about 5% by weight of a complex salt selected from triarylsulfonium hexafluorophosphate, triarylsulfonium hexafluoroantimonate, triarylsulfonium hexafluoroarsenate and triarylsulfonium tetrafluoroborate; and (b) at least about 15% by weight of liquid neutral oxyethylene-containing material selected from: (i) compounds having the formula R[(OC.sub.2 H.sub.4).sub.n (OC.sub.3 H.sub.6).sub.m OH].sub.p where R is a polyvalent neutral organic radical having a valence of p, n + m is in the range of 1 to about 25, p is in the range of 2 to 6, wherein the oxyethylene units in such compounds constitute at least about 15% by weight of such compounds; and wherein the number of carbon atoms in R divided by the product of n and p is less than three; and (ii) compounds having the formula: R.sup.1 (OC.sub.2 H.sub.4).sub.n (OC.sub.3 H.sub.6).sub.m OH where R 1 is monovalent neutral organic radical, where n + m is in the range of 1 to about 25, wherein the oxyethylene units in such compounds constitute at least about 50% by weight of such compounds; and (iii) compounds of the formula: H(OC.sub.2 H.sub.4).sub.n (OC.sub.3 H.sub.6).sub.m OH where n + m is in the range of 2 to about 25, wherein the oxyethylene units in such compounds constitute at least about 15% by weight of such compounds; wherein said salt is dissolved in said oxyethylene-containing material.
