DETAILED DESCRIPTION OF THE INVENTION (A) Industrial Application Field The present invention provides a free acid represented by the following general formula (I) (wherein R represents an alkyl group of C4 to CL). It relates to a method for dyeing natural and synthetic materials, characterized in that it uses trisazo dyes.

(b) Conventional techniques and problems Conventionally, in order to dye natural and synthetic materials black,
Dyes based on benzidine-based compounds have been used in large quantities, but in recent years, the carcinogenicity of benzidine, the base of these dyes, has become a problem, and their production has been discontinued. Although various developments have been made, none of them have yet produced sufficiently satisfactory results.
