A water-soluble coating or other deposit is produced from a formulation that is comprised of a curable liquid substance and a dispersed, particulate effervescing agent. The formulation is particularly useful as a solder resist in the manufacture of PCBs, and the preferred composition contains n-vinyl-2-pyrrolidone, N,N-dimethylacrylamide, and polyvinylpyrrolidone.
