摘要:
Anthrapyrimidine dyes of the formula: ##SPC1##In whichA is saturated alkylene of two to eight carbon atoms or cycloalkylene of six to eight carbon atoms; and ##EQU1## B is hydrogen, or IN WHICH X is saturated alkyl of one to nine carbon atoms which may bear other substituents, phenalkyl, a five-membered or six-membered heterocyclic ring, --NHR or --OR in which R is alkyl of one to six carbon atoms, cycloalkyl of six to eight carbon atoms or unsubstituted or substituted phenyl. On synthetic fibers or in thermoplastics the dyes give yellow to orange colorations which have very good fastness properties.
摘要:
Anthraquinone dyes of the formula ##STR1## where R is C.sub.1 -C.sub.10 -alkyl, C.sub.5 -C.sub.8 -cycloalkyl, alkoxyalkyl of a total of 3 to 11 carbon atoms, phenoxyalkyl, where alkyl is of 2 to 4 carbon atoms, or phenyl-C.sub.1 -C.sub.4 -alkyl.On synthetic fibers and blends thereof with cellulosic fibers, the dyes give brilliant clear blues.The dyes are particularly suitable for transfer printing onto synthetic fibers and give high color yields. The transfer prints obtained have excellent fastness characteristics.
摘要:
Aqueous dye formulations which contain one or more sparingly water-soluble, or water-insoluble, phthalocyanine-sulfonamides of the formula ##STR1## where A is a (n+m)-valent radical of copper phthalocyanine, cobalt phthalocyanine or nickel phthalocyanine which may be substituted by up to 4 chlorine or bromine atoms, R is hydrogen, alkyl of 1 to 5 carbon atoms or alkoxyalkyl of a total of 3 to 7 carbon atoms, R.sup.1 is a substituted or unsubstituted aliphatic, cycloaliphatic, araliphatic or aromatic radical, or ##STR2## is a saturated 5-membered or 6-membered heterocyclic ring, X.sup..sym. is H.sup..sym., an alkali metal ion, (NH.sub.4).sup..sym. or ##STR3## (where R and R.sup.1 have the above meanings), n is 2, 3 or 4 and m is 0 or 1, together with one or more conventional dispersing agents and humectants and with or without a disinfectant. The formulations give very fast prints and dyeings on cellulose and on cellulose-containing fibers.

摘要:
Dyes of the formula ##STR1## where F is an (m+n)-valent radical of a quinophthalone, dioxazine, indigo, quinacridone, triphenylmethane or rhodamine dye, M.sup..sym. is H.sup..sym. or one equivalent of a metal cation, m is 0, 1 or 2 and n is 1, 2, 3 or 4, and their salts, are very useful for dyeing and printing paper. If they are used for wet-end dyeing, the waste water is virtually colorless. The colorations obtained exhibit good lightfastness and good bleeding fastness.
摘要:
A thermally insulating coating system for curved and/or hardened glass panes includes at least one layer of noble metal enclosed by a lower and an upper blocker layer. An underoxidic NiCrOx layer with a thickness between one Å and two nm is embedded into the noble-metal layer. The advantage is that the optical qualities of the coating system are not influenced by the tempering and curving of the glass pane.

Imidazolylmethylene-containing triphendioxazine dyes of the formula I ##STR1## where R.sup.1, R.sup.2, R.sup.3, R.sup.4, m and n each have defined meanings, A.sup..crclbar. is an anion and F is the radical of a triphendioxazine chromophore of the formula II ##STR2## where X.sup.1, X.sup.2, X.sup.3, X.sup.4, X.sup.5, L and p each have defined meanings, are useful for dyeing and printing material containing cellulose fibers.
摘要:
Paper is colored by a process in which a compound which, in the form of the free acid, is of the formula I ##STR1## where, in each case independently of one another, A is unsubstituted or methyl substituted C.sub.1 -C.sub.6 -alkylene or vinylene,R is each hydrogen or C.sub.1 -C.sub.4 -alkyl,X is each --CO-- or --SO.sub.2 --,K is each a cationic group andY is hydrogen, chlorine or bromine.
摘要:
It is provided a lamp, particularly halogen lamp, for a headlight of a motor vehicle, comprising a light source (12) for emitting mainly white light, a mainly transparent envelope (14) encapsulating the light source (12) and a filter element (22) provided at the envelope (14), wherein the filter element (22) is adapted for deflecting visible light of a predefined wavelength interval such, that mainly blue light can be provided above a bright/dark-cutoff (28). Since the deflected bluish light is above the bright/dark-cutoff (28) an oncoming driver recognizes earlier the light. At the same time the oncoming driver is not blinded by the blue light above the bright/dark-cutoff (28), since not the whole emitted light (40) but only a smaller wavelength interval is directed above the bright/dark-cutoff (28).
