“…And they are therefore widely studied in various fields, such as textiles, leather, medicine, responsive materials and fluorescent materials. [2][3][4][5][6][7][8] Polymer dyes can modulate their properties by changing the structures of polymers and chromophores according to the application performance requirements. They may be used as water-soluble polymer dyes that achieve coloration of fibres in aqueous solution [9][10][11][12] and improve the adsorption capacity of dyes on fibres due to the adhesion of polymers, thus improving their dyeing ability and fastness.…”

To obtain a new type of macromolecular reactive dye with high fixation and good light fastness, poly(styrene‐co‐maleic acid) was synthesised by co‐polymerisation of styrene and maleic anhydride, then, through nitration, reduction, diazotisation and coupling reaction, novel macromolecular reactive dyes were prepared with a solubility greater than 60 g/L. The dyes were used to dye cotton fabrics; the results showed their fixation was more than 92%, and both the rub and wash fastness of the dyes were good. The light fastness of the red and blue dyes with the ethoxy group on melamine was grade 4, and for the yellow dye reached grade 5. The poly(styrene‐co‐maleic acid) macromolecular reactive dyes exhibit very good application prospects in practice.

“…Dyes and pigments play an important role in our daily life because they can be widely used in many applications as key ingredients in cosmetics, paints, textiles, coatings, plastics, construction materials, food, paper, and printing inks [ 1 ]. The global colorants market has in recent years been greatly enhanced as a result of the steadily increasing needs of various end-use industries pertaining to dyes and pigments.…”

“…The composite dyes/pigments may show improved performance due to the interaction between functional molecules. For example, Guo et al [ 1 ] prepared GO-modified polymer dyes by introducing GO into aqueous polyurethane-based polymer dyes. The modified polymer dyes exhibited high coloration rates and their dry/wet rubbing fastness and migration resistance were both improved to grade 5, which promoted their application in high-performance leather dyeing.…”

Composite materials and their applications constitute a hot field of research nowadays due to the fact that they comprise a combination of the unique properties of each component of which they consist. Very often, they exhibit better performance and properties compared to their combined building blocks. Graphene oxide (GO), as the most widely used derivative of graphene, has attracted widespread attention because of its excellent properties. Abundant oxygen-containing functional groups on GO can provide various reactive sites for chemical modification or functionalization of GO, which in turn can be used to develop novel GO-based composites. This review outlines the most recent advances in the field of novel dyes and pigments encompassing GO as a key ingredient or as an important cofactor. The interactions of graphene with other materials/compounds are highlighted. The special structure and unique properties of GO have a great effect on the performance of fabricated hybrid dyes and pigments by enhancing the color performance of dyes, the anticorrosion properties of pigments, the viscosity and rheology of inks, etc., which further expands the applications of dyes and pigments in dyeing, optical elements, solar-thermal energy storage, sensing, coatings, and microelectronics devices. Finally, challenges in the current development as well as the future prospects of GO-based dyes and pigments are also discussed. This review provides a reference for the further exploration of novel dyes and pigments.

“…Hydrophilic chain extenders are introduced to give it a certain water solubility, so it can be directly emulsified and dispersed in water without emulsifier. WPU, a very promising environmental material, has broad applications in industries 12–15 . The isocyanate group is the terminal group of WPU and is usually protected by a blocking agent.…”

In order to make up for the lack of washing fastness and chlorinated water fastness of nylon dyed with acid dyes, an aminosiloxane modified cationic waterborne polyurethane (KWPU) with the ability to reversibly adsorb chloride ions was synthesized. N‐methyldiethanolamine and ethylenediamine was used as chain extender. N‐aminoethyl‐γ‐aminopropyltrimethoxysilane was used to block the remaining isocyanate groups and provide secondary amine groups for reversible adsorption of chloride ions. The structure of KWPU was characterized by Fourier transform infrared spectrometry (FTIR), scanning electron microscopy (SEM), 1H NMR, and differential scanning calorimetry (DSC). Particle size and zeta potential were tested to evaluate the emulsion stability. The research results showed that when the N‐methyl diethanolamine content was 14%, the water absorption rate of KWPU film was 82.1%, and when the KH‐792 content was 6%, the water absorption rate of KWPU was 34.8%. The addition of siloxane can significantly improve the thermal resistance of the KWPU film. The color fastness of the dyed nylon fabric treated with KWPU emulsion was significantly improved, the rubbing fastness was improved by 0.5 or 1 grade, the washing fastness was improved by 1 grade, and the fastness to chlorinated water was improved by 1.5 or 2 grade.
