Abstract
Novel phthalocyanine compounds are described, which have the formula ##STR1## in which MePc is the Si(IV)-, P(V)-, Ti(IV)-, Ge(IV)-, Cr(IV)-, Ga(III)-, Zr(IV)-, In(III)-, Sn(IV)- or Hf(IV)- phthalocyanine or -naphthalocyanine ring system, A is an anionic, nonionic or cationic group which imparts solubility in water, Z is the counter-ion to A, if the latter is an ionic group, and is 0 if A is a nonionic group, n is any desired number from 1 to 8, Y is a neutral substituent which does not impart solubility in water and p is any desired number from 0 to 6, it being possible for the groups AZ and Y present in the molecule to be identical or different in either case, and the sum of n+p being not more than 8 and MePc not being the Sn(IV)-phthalocyanine or Sn(IV)-naphthalocyanine ring system if p is 0 and if the only groups imparting water-solubility in the molecule are sulfo groups. The novel compounds can be used as photoactivators, particularly for bleaching textiles and for controlling microorganisms in or on organic or inorganic substrates. Bleaching, washing and steeping agents and agents having antimicrobial activity, which contain the novel phthalocyanine compounds, are also described.
