The present invention relates to storage-stable dye salts, solutions and compositions thereof a process for their preparation and their use for dyeing and/or printing substrates.

Storage-stable dye solutions

The invention relates to basic bisazo compounds according to formula (I) wherein all substituents are defined as in Claim, their production, their use as dyestuffs as well as material dyed with these dyestuffs.

Basic bisazo compounds

The present invention relates to a process for producing storage-stable concentrated aqueous dye preparations of anionic dyes, to the dye preparations as such, blends/shadings with further anionic dyes and to their use, especially for printing and dyeing fiber materials.

Concentrated aqueous compositions of dyestuffs

The invention relates to basic mono- and bisazo compounds according to formula (I) wherein all substituents are defined as in Claim 1, their production, their use as dyestuffs as well as material dyed with these dyestuffs.

Basic mono- and bisazo compounds

The invention relates to the use of disazo compounds according to formula (I)wherein all substituents are as defined in claimsalts thereof and mixtures of these compounds for dyeing or printing organic substrates, to novel compounds, to the process for the production of these compounds and to substrates dyed or printed by these compounds.

Use of disazo compounds

Bridged disazo compounds

Reactive monoazo dyestuffs and the processes in which they are produced

The invention relates to monomeric or polymeric organic compounds having non-linear optical properties, to their production and to their use as electrooptical, photorefractive or holographic devices, especially as modulators, switches, amplifiers, wave guides, sensors to work as sequence transformation especially frequency doubling. These compounds are compounds of Formula I: ##STR1## in which R.sub.1 is a group for formula a ##STR2## or R.sub.1 is a group of formula b ##STR3## or R.sub.1 is an NO.sub.2 where R.sub.1`-R.sub.11 are organic radicals.

Compounds having non-linear optical properties

Complexes of the formula ##STR1## and salts thereof, wherein each of R.sub.1 -R.sub.4 is independently hydrogen, halo, nitro, C.sub.1-4 alkyl, C.sub.1-4 alkoxy, --NHCOR.sub.8, --COX or --SO.sub.2 Z,

Copper complexes of further substituted

Complexes of the formula ##STR1## and salts thereof each cation of which is independently a non-chromophoric cation,

Copper Complexes of disazo compounds having two substituted

Tetrakisazo compounds of the formula ##STR1## and salts thereof, wherein
