发明名称 Method or dyeing using phase change dyestuffs
摘要 Method is set forth of dyeing a material comprising forming a solution having a basic salt of a water soluble dye of the formula: <IMAGE> (I) wherein n is 0 or 1; m is 0 or 1; m=1 when n=0; p=0 when m=1; p=1 when m=0; the subscripts 1 and 0 indicating, respectively, the presence and absence of the substituent subscripted; Y is CR2 COO, CR2CR2COO or CR2CR2CR2COO; each R is independently hydrogen, methyl, ethyl, phenyl or phenyl substituted with methyl, ethyl, halo, cyano, ethynyl or nitro; G is CR, CR2CR, CRCR2, CR2CR2CR, CR2CRCR2 or CRCR2CR2; E is OH, SH or NH2; when G of GE includes more than one carbon atom the substituent E is attached to a carbon atom selected such that the two end carbon atoms of G are attached, one to the Dye and the other to the nitrogen; and Dye indicates a color imparting moiety; positioning the aqueous solution adjacent to a material; and applying sufficient dry heat to the material to convert the dye to a hydrophobic form thereof having the formula: <IMAGE> when n = 1, and m = 1 and p = 0; <IMAGE> when n = 1, m = 0 and p = 1; and <IMAGE> when n = 0, m = 1 and p = 0. Also set forth are certain novel dyestuffs of the formulas (II), (III), (IV) and (V) including, in particualr, dyestuffs of the formula: <IMAGE> (VI) wherein X is O, S or NH along with a method of synthesizing dyestuffs of the formula (VI).
