摘要:
The invention is related to a weather-resistant dye and use thereof, which contains in molecules thereof not only chromophoric parent D, but also electron-accepting group Q which is linked with dye parent D through non-conjugated carbon link L to constitute D-L-Q dye molecule; the electron-accepting group Q has such a HOMO energy level that is lower than the HOMO energy level of the dye chromophoric parent D. The dye has sun-resistance and anti-ozone performances, which can be used as colorant in the ink, dope, lacquer, toner powder for laser printing, marker, paper, fabric, glass, porcelain or polymer.
摘要:
Die Erfindung betrifft ein neues Verfahren zur Herstellung von wasserlöslichen Phthalocyaninfarbstoffen, die in Form ihrer freien Säuren der Formel entsprechen, worin die Substituenten und Indices die im Anmeldungstext angegebene Bedeutung besitzen, welches dadurch gekennzeichnet ist, daß man ohne Isolierung von Zwischenstufen nacheinander ein Phthalocyanin-Sulfochlorid mit einer Verbindung gegebenenfalls unter Zusatz eines Amins umsetzt und anschließend durch Umsetzung mit Halogentriazinylkomponenten in die Farbstoffe der Formel (I) überführt.
摘要:
Described are cuprophthalocyanine type compounds represented by formula [1] in the form of the free acid (wherein D is a cuprophthalocyanine radical; B is an alkylene group of 2 to 4 carbon atoms or a phenylene group which may have one or two carboxyl group(s) or sulfonic acid group(s) as a substituent(s); R is a lower alkyl group or a lower alkoxy-lower alkyl group; X is a carboxyl group or a carbamoyl group and combines with the 3- or 4-position of the pyridine ring; / is 1, 2 or 3; m is 0, 1 or 2; n is 1 or 2; and the sum of /, m and n is 2, or 4) as well as a method for dyeing cellulosic fiber materials using the said compounds.

摘要:
Reactive phthalocyanine dyes are represented by the general formula
in which (Pc) is a copper or nickel phthalocyanine residue and R 1 , R 2 , R 3 , (A), (B), X, Y, f, m and n are as defined in the description. The dyes are capable of dyeing cellulose fiber or mixed fibers of polyester and cellulose to yield Turkish blue-dyed fibers having excellent color fastness to light and to washing.
