Abstract

The invention provides novel bisazo compounds obtained by coupling two 2-hydroxynaphthalene-3,6-dicarboxylic acid derivatives and a compound having two diazo groups, as well as a process for producing the same. The present compounds are superior in resistance to water, chemical agents, solvents, heat and the like.
