PURPOSE: To obtain a dye having color build-up, remarkable deep color and good fastness by reacting a specific compd. having a dye residue contg. sulfo or carboxyl group with a specific silicon-contg. compd.
CONSTITUTION: The objective dye shown by formula III is obtained by the reaction of a compd. shown by formula I with a compd. shown by formula II. In the formulas, F is a dye residue having sulfo- and/or carboxyl-; (s) is 1, 2 or 3; ZO is a residue shown by formula IV or the like; R is H or the like; W is a group shown by formula V; RD is H or the like; RE is 1-4C alkyl or the like; RF is 1-8C alkoxy; D0 is 1-6C alkylene or the like; X1 is -S- or the like; X2 is -S- or the like; (a) is 0 or 1; (b) is 0-10; A is 1-6C alkylene; B is 5-8C cycloalkylene; Z is formula VI or the like; R' is H or the like; RA is H or the like; RB is 1-4C alkyl or the like; RC is H or the like; U is formula VII or the like; RH is 1-6C alkyl.
