Abstract
Azo chromophores having polyoxyalkylene substituents are linked together by a covalent bond or by an intervening connecting group to form dimers or trimers. The polyoxyalkylene substituents are straight or branched chain polymers primarily of ethylene oxide which make the dimer and trimer colorants useful as fugitive tints.
