MagentaLe magenta est un colorant rouge violacé d'aniline de synthèse inventé en 1858, appelé fuchsine ou roséine. C'est aussi la désignation normalisée du colorant primaire absorbant le vert dans la synthèse soustractive des couleurs en imprimerie et en photographie argentique.
Masse molaireLa masse molaire est la masse d'une mole d'une substance (un corps simple, un composé chimique). Elle s'exprime en grammes par mole (g·mol−1 ou g/mol).

QuinacridoneLes pigments de quinacridone sont des pigments organiques de synthèses qui vont du rouge-orange au rouge-violet.
Ils sont utilisés depuis les années 1960 par les teinturiers et les fabricants de pigment set couleurs à peindre (et plus récemment par certains tatoueurs, comme pigment dans des encres de tatouage, avec un risque allergique).
Il s'agit de pigments très transparents, au fort pouvoir colorant mais modérément couvrants.
Leur transparence permet de varier les teintes selon la densité et l'épaisseur de l'application.
Terpolymère styrène anhydride maléïqueIndex. décimale : 667.2 Colorants et pigments Résumé : The stability of water-based pigment dispersions is a key factor in determining their utility in ink-jet applications, and the appropriate choice of dispersant plays a special role. Among the pigment formulations tested to date, literature data on magenta pigments are very limited. Thus, the goal of this work was to study the influence of the type and loading of dispersants on the quality and stability of quinacridone magenta pigment dispersions. Three different commercially available dispersants were tested: (1) a cationic styrene-maleic anhydride copolymer, (2) an anionic polyacrylate, and (3) a nonionic alkyl ethoxylate. Pigment and dispersing agents were analysed using the Fourier Transform–infrared method. The stability of pigment dispersions was determined by comparative studies of changes in the pigment particle size, viscosity, pH, filtration time, optical density and gloss during the accelerated ageing test. Moreover, Turbiscan AGS and LUMiFuge analysers were used for evaluations of the instability of the dispersions. The properties of each dispersing agent affected the performances of the different dispersants. The highest stability for the pigment formulations was provided using the nonionic dispersant (small particle size, < 60 nm; the lowest viscosity < 60 mPa·s at the optimal dispersant content; favourable results of the filtration test; the highest pigment dispersability, proven by optical density and gloss). The Turbiscan AGS and LUMiFuge results indicated that the stability of all tested quinacridone magenta pigment dispersions was excellent (Turbiscan Stability Index values below three, and no significant differences in transmission profiles, respectively). However, it was found that the measurement results were influenced by the viscosity of the formulations. Note de contenu : - EXPERIMENTAL : Materials - Equipment and measuring conditions - Methods

Noir de carboneIndex. décimale : 667.2 Colorants et pigments Résumé : The influence of dispersing additives on the electrical conductivity of carbon black pigments dispersed in an organic medium was studied. Two dispersing additives were examined in combination with two different carbon blacks, a conductive carbon black and a nonconductive one. These carbon blacks differ in the size of their aggregates and in the amounts of surface oxygen groups. Both of the additives form a monolayer when adsorbed on either of the pigment surfaces. FTIR studies showed that chemical bonding of one of the additives on the surfaces of both pigments had occurred. Conductivity decreases with increasing additive concentration, but in the case of the chemically bonded additive, the conductivity of the dispersion remained high even at higher additive loadings. This study helps in understanding the effects such additives have on the specific conductivity of composite materials that contain dispersed carbon black pigment particles.

Impression hélioIndex. décimale : 667.2 Colorants et pigments Résumé : Writing inks were first manufactured in both Egypt and China about 4500 years ago. These inks were based on soot bound with gums. Printing was invented by the Chinese about 3000 years later. They used a mixture of coloured earth, soot and plant matter for pigments, again mixed with gums as binder. By 1440, when Johannes Gutenberg invented the first printing press with moveable type, ink was made of sood bound with either linseed or varnish. Coloured inks were introduced in 1772 and drying agents were first used in the nineteenth century. Note de contenu : - Design of TiO2 pigments

PigmentsIndex. décimale : 667.2 Colorants et pigments Résumé : The development activities of pigment producers are driven by the market needs of coatings industries. In the field of effect pigments, the main driver for ongoing innovation is the desire of industrial paint designers to get the best tools for exciting colour styling. The exterior design of an article is mainly determined by shape, colour and haptic impression. During the first minutes of exposure to an article, a customer usually decides whether he has a deeper interest or not. For that reason, inspiring colours - very often with special effects - are needed in all areas.
The main requirements of the castings industry are effect pigments, which allow higher brilliancy and chroma, stronger sparkle, cool white and black shades. Besides improved colouristic properties an ongoing demand is for further improvements in technical feasibility of colour shades, especially for better hiding basecoats. Recently launched innovative pigments are bluish pearl pigments based on synthetic mica and iron oxide-coated aluminium flakes of silver dollar type.Note de contenu : - Technology trends in effect pigments manufacturing
