Abstract
PURPOSE: To dye or print a hydrophobic fiber in a bright red with excellent sublimation fastness at low cost, by use of a thiadiazolylazo dye obtd. from a 2-aminothiadiazole deriv. and an arom. aine deriv.
CONSTITUTION: A 2-aminothiadiazole deriv. of formula I(wherein X is S or O) is diazotized in a mineral acid (e.g., hydrochloric or sulfuric acid) or an org. acid (e.g., acetic acid) and then coupled with an arom. amine deriv. of formula II (wherein R1 is H, alkyl or alkoxy; R2 and R3 are H, alkyl or alkenyl; R4 is H, halogen, lower alkyl, acylamino or ureido), to prepare a thiadiazolylazo dye of formula III. The dye is crushed into a minute particle and dispersed into an aqueous medium and a hydrophobic fiber (e.g., polyester or polyamide) is dyed by immersion in the dye both obtd. followed by pressing and heating.
