ABSTRACT:
Dyes of the formula ##STR1## WHEREIN F is a dye of the disperse class, n is 1 or 2, and W is the radical of a diammonium or aminoammonium compound which is linked through an ammonium group to the methylenecarbonyloxy radical, said dyes finding utility in dyeing and printing hydrophobic synthetic organic materials, especially polyester materials in an aqueous dyebath at elevated temperatures, whereby the carbacyl group undergoes hydrolysis to form a disperse dye which exhausts onto the material.
