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.

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:
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).
