From the beginning of organised motor sport events, in the early 1900s, until the late 1960s, before commercial sponsorship liveries came into common use, vehicles competing in Formula One, sports car racing, touring car racing and other international auto racing competitions customarily painted their cars in standardised racing colours that indicated the nation of origin of the car or driver.
The maximum color dosage depends heavily on the polymer used (particle size, surface finish and surface energy), the machine configurations and the pigment load of the liquid color. [1] This can cause problems with very thin-walled parts that must be colored as opaque as possible, or even prevent coloring with liquid color altogether.
Formula One sponsorship liveries have been used since the 1968 season. Before the arrival of sponsorship liveries in 1968 the nationality of the team determined the colour of a car entered by the team, e.g. cars entered by Italian teams were rosso corsa red, cars entered by French teams were bleu de France blue, and cars entered by British teams (with several exceptions, such as cars entered ...
Sudan I (also known as CI Solvent Yellow 14 or Solvent Orange R) [1] is an organic compound typically classified as an azo dye. [2] It is an orange-red solid, used to color waxes, oils, petrol, solvents, and polishes. Historically, Sudan I used to serve as a food coloring agent, notably for curry powder and chili powder.
The late 1850s saw the introduction of the first modern synthetic dyes, which brought more color and variety of color to Europe. In addition to being multi-varied and extraordinarily intense, these new dyes were notoriously unstable, rapidly fading and turning when exposed to sunlight, washing, and other chemical or physical agents.
It has the appearance of an orange powder. Aniline Yellow was the first azo dye. it was first produced in 1861 by C. Mene. The second azo dye was Bismarck Brown in 1863. Aniline Yellow was commercialized in 1864 as the first commercial azo dye, a year after aniline black. It is manufactured from aniline.
Methyl yellow, or C.I. 11020, is an organic compound with the formula C 6 H 5 N 2 C 6 H 4 N(CH 3) 2. It is an azo dye derived from dimethylaniline. It is a yellow solid. According to X-ray crystallography, the C 14 N 3 core of the molecule is planar. [3] It is used as a dye for plastics and may be used as a pH indicator.
Sunset yellow FCF (also known as orange yellow S, or C.I. 15985) is a petroleum-derived orange azo dye with a pH-dependent maximum absorption at about 480 nm at pH 1 and 443 nm at pH 13, with a shoulder at 500 nm.
