摘要:
A process for the dyeing or printing of a hydrophobic organic fibrous material containing or consisting of polyester, wherein(a) the fibrous material is dyed (.alpha.) from an aqueous dispersion with a dyestuff of the formula (1) indicated below at a pH value between 2 and 9 and at a temperature above 100.degree. C. or at about 100.degree. C. in the presence of a carrier, or (.beta.) by impregnating it with an aqueous dispersion of a dyestuff of the formula (1), said dispersion having a pH value between 2 and 9, and subsequently exposing the fibrous material so treated to a short heat treatment between about 180.degree. and 210.degree. C., or(b) the fibrous material is printed with a dyestuff of the formula (1) by the transfer printing method, the dyestuff used in methods (a) and (b) being of the formula (1) ##STR1## in which X represents alkyl of 1 to 4 carbon atoms, phenyl, lower alkyl-phenyl, lower alkoxy-phenyl, nitro-phenyl, chloro-phenyl or bromo-phenyl, and D represents phenyl, lower alkyl-phenyl, lower alkoxy-phenylene, nitro-phenylene, chloro-phenylene, benzoyl-phenylene, phenyl-phenylene, phenoxy-phenylene, lower alkyl-sulfonyl-phenylene, aminocarbonyl-phenylene, aminosulfonyl-phenyl, ##STR2## chloro-nitro-phenyl, lower alkyl-nitro-phenyl, lower alkoxy-nitro-phenyl, di(cyano)-phenyl, trifluoromethyl-nitro-phenyl or hydroxyalkoxy-nitro-phenyl.
摘要:
Dyes useful for transfer printing and having the formula ##STR1## in which X and Y are hydrogen or halogen,Z is hydrogen or methyl,R.sup.1 is hydrogen, lower alkyl or alkoxy,R.sup.2 is hydrogen, chlorine, lower alkyl, alkoxy, alkanoylamino or pyrrolidonyl, andR.sup.3 and R.sup.4 are alkyl optionally substituted by alkoxy, chlorine, alkanoyl or alkoxycarbonyl. The dyes are especially useful for the transfer printing of polyamides, giving prints having very good light and wet fastnesses.

The application is concerned with the composition of matter composed of a brown dye of the formula: ##STR1## and a blue dye of the formula: ##STR2## useful in marking heat transfer prints in black shades; heat transfer sheets carrying such composition; inks for printing the transfer sheets; a heat transfer process for black prints on polyester and novel heat transfer printed fabrics.
摘要:
Use of the dyestuffs of the formula ##STR1## wherein R, Y and X have the meaning given in the description, for the dyeing of synthetic textiles, especially those of aromatic polyesters, by the transfer printing process.Prints obtained are distinguished by good fastness in use properties.
摘要:
A process for the transfer color printing of synthetic textile materials which comprises placing a transfer material which carries a colored pattern derived from one or more disperse dyestuffs each containing at least one carboxylic acid group in contact with a synthetic textile material and heating the transfer material and the synthetic textile material while in contact so as to transfer the dyestuff from the transfer material to the synthetic textile material.
