Colour-fast monoazo dye, its manufacture and its useHubert DI KruseKühlwein, Jürgen, DrBühler, Ulrich, Dr
Azo compounds (specifically azo dyes) are widely used in the footwear, furniture and fashion industries to dye natural textiles, synthetic textiles and leather. This is because they produce a huge variety of colours and provide good colour fastness properties, and so do not lose their colour or...
Azocolourants and Azodyesare one group of synthetic dyestuffs based on nitrogen that are often used in textile industry. Some AZO dye stuffs may break down under certain conditions to produce carcinogenic and allergenic aromatic amines. Azocolourants and Azodyes and REACH annex XVII Azocolourants ...
Azo dyes usually exist in the trans configuration although exposure to light in certain structures can cause partial isomerization to the cis form which causes small colour changes (known as photochromism). Any dye exhibiting this phenomenon cannot be considered for commercial purposes. However, ...
Dye mixtures containing azo dyes having the same colour and coupling component from diaminopyridine series公开了含有通式(I)所示的至少4种相同颜色的染料混合物,其中R Discloses a dye mixture containing formula (I) as shown in at least four of the same color, wherein RG·兰姆...
To produce special colour shades, besides the dyes of the general formula (I) or (II) according to the invention, it is possible to add to the agents according to the invention one or more additional customary direct dye from the group consisting of acidic dyes, basic dyes, nitro dyes, ...
electron system with conjugated double bonds, such as carbonyl (=CO), carbon-nitrogen (-CH=N-), azo (-NN-), and nitro (=NO2), whereas an autochrome is an electron-withdrawing unit that intensifies the colour and provides a bonding group to the dye complex (Benkhaya et al., 2020). ...
Azo dyes can be used to color or dye a large class of materials and products, particularly for fabric, leathers, and plastics for which a bright color is required. In this section, we list several categories of products and materials that might contain restricted azo dyes. Textiles Textile an...
