摘要:
The present invention relates to a pigment formulation which comprises at least one organic pigment selected from C.I. Pigment Red 279 or C.I. Pigment Orange 80 (both thiazine indigo pigments) and at least one pigment-dispersing agent. The invention further relates to a process for preparing said formulation as well as to a method of pigmenting high molecular weight organic material of natural or synthetic origin with said formulation.
摘要:
Dye mixture containing at least one dye of the formulae (1)(formula see enclosed paper copy)and at least one dye of the formulae (2)(formula see enclosed paper copy)where the substituents are each as defined in the claims. These mixtures are useful for dyeing or printing fibre materials comprising polyester and/or cellulose acetate.
摘要:
The present invention provides anthraquinonyl and anthronyl dyes and dichroic light polarizers based on the dyes. The dichroic light polarizer includes two separate embodiments. In the first embodiment, the dye molecules are aggregated into particles oriented in a predetermined direction on the surface of a substrate to enable the dye to polarize light transmitted through the dye. In the other embodiment, the dye molecules are molecularly oriented in a non-periodic arrangement of different polarizing elements on the surface of a substrate. Each of the polarizing elements has a differing orientation of the polarization vector in the substrate plane and/or a different color. The dichroic light polarizer may contain one or more additional dye layers and may have a transparent layer intermediate between the dye layers.
worin x eine ganze Zahl zwischen 1 und 4 bedeutet,
A für den Rest eines Chromophors der Chinacridon-, Anthrachinon-, Perylen-, Indigo-, Chinophthalon-, Isoindolinon-, Isoindolin-, Dioxazin, Phthalocyanin, Diketopyrrolopyrrol- oder Azoreihe steht, der x mit B verbundene N-Atome, vorzugsweise mit mindestens einer unmittelbar benachbarten oder konjugierten Carbonylgruppe, enthält. B für eine Gruppe der Formel steht, und, wenn x 2, 3 oder 4 bedeutet, auch ein-, zwei- oder dreimal Wasserstoff sein kann, wobei Q eine Gruppe der Formel ist Diese löslichen Chromophore können sehr leicht durch Erhitzen, selbst im Substrat, in welchem sie problemlos in gelöster Form eingearbeitet werden können, zu den entsprechenden Pigmenten umgewandelt werden.
Für die Bedeutung der Reste R 1 -R 8 wird auf Anspruch 1 verwiesen.
摘要:
An improved mordant solution and process for preparing fibers for dyeing and fixing natural dyes to fibers, particularly but not exclusively cellulose fibers, including cotton and linen, and synthetic fibers, including Rayon3 and Tensel . The improved natural mordant solution comprises an aqueous solution of alum KA1(SO4) and soda ash Na2CO3, most preferably an aqueous colloidal suspension of aluminum hydroxide. This mordant solution significantly improves the recognized measurable qualities of naturally dyed fibers, including light and washfastness, without using polluting heavy metal mordants. The improved mordant treatment and natural dye process includes first pretreating the fabric with an aqueous mordant wash, which increases the dye uptake in the dye bath, then treating the fabric with a second aqueous mordant wash, following dyeing, then preferably treating the dyed fabric with a final tannin wash, permanently setting the natural dye in the fibers or fabric.
