Abstract: The novel diphenyl methane cpds. have formula (I). (where R' is Et or Pr substd. by CN, Cl, OH, MeO, EtO, acetoxy, beta-cyanethoxy, N,N-dimethyl or N,N-diethylamino; R2 = R' or 1-4C alkyl, and R' and R2 are the same or different, R3 = H, Ml, Et, MeO or Cl). (I) can be converted by oxidn. into novel benzophenone derivs. useful as photosensitisers or components of photo-iniator systems. The benzophenone derivs. are less toxic than Michler's ketone whilst having similar photosensitising activity, are more sol. in many organic solvents and are more compatible with many photopolymerisable mixts.

Abstract: Auramine salts having an ester of sulfopropionic acid as anion. The salts are more stable in storage than known auramine salts and therefore very suitable for the preparation of storage-stable solutions.
