Abstract
The invention relates to symmetrical cyanine dyes of the formula <FORM:1084435/C4-C5/1> wherein R1 is an alkyl, aralkyl, aryl or allyl group or a group Z1-OR3 where R3 is an alkyl or acyl group and Z1 is an alkylene chain of 1-6 C, R2 is an alkyl group, Z is an alkylene chain of 1-6 C, Q is Cl or Br, n is 1 or 2 and X is an anion. The dyes are prepared by the usual condensation of an appropriate quaternary salt with chloral alcoholate or an alkyl ortho-formate.
