The photodecomposition of the title compounds is studied by ESR spectroscopy using a spin‐trapping agent. The radicals observed indicate the breakdown of the title compounds and the simultaneous generation of sulphonic acid. Confirmative evidence for the photoinduced release of sulphonic acid is provided by the acid‐catalysed crosslinking of a melamine resin.
