Pigment Red 179 is an organic compound used as a pigment. Structurally, it is a derivative of perylene, produced from perylenetetracarboxylic dianhydride through derivatization with methylamine. [1] [2] It is used in watercolor paints, usually labeled as Perylene Maroon.
As all madder-based pigments are fugitive, artists have long sought a more permanent and lightfast replacement for rose madder and alizarin. Alternative pigments include: Anthraquinone red (PR177), a chemical cousin of Alizarin [3] Benzamida carmine (PR176) [3] Perylene maroon (PR179), for mixing dull violets [3] Pyrrole rubine (PR264) [3]
Copper pigments. Han purple: BaCuSi 2 O 6. Cobalt pigments. Cobalt violet (PV14): Co 3 (PO 4) 2. Manganese pigments. Manganese violet: NH 4 MnP 2 O 7 (PV16) manganic ammonium pyrophosphate. [2] Gold pigments. Purple of Cassius: Gold nanoparticles suspended in tin dioxide - Au x • SnO 2. Arsenic pigments. London purple As 2 O 3. [3]
Several perylene pigments have been developed for artist's paints : Pigment red 149, a middle red, between light and dark cadmium red. (chemical structure: replace HN group in PV29 with 3,5-(CH 3) 2 C 6 H 3). Pigment Red 179, which is close to alizarin crimson (chemical structure: replace HN group in PV29 with CH 3 N).
Lithol Rubine BK is a reddish synthetic azo dye.It has the appearance of a red powder and is magenta when printed. It is slightly soluble in hot water, insoluble in cold water, and insoluble in ethanol.
Naphthol Red (Pigment red 170 or PR170) is an organic pigment extensively used in automotive coatings and painting.. It is produced synthetically by converting p-aminobenzamide into the corresponding diazonium compound followed by coupling with 3-hydroxy-2-naphththoic acid (2-ethoxy)anilide ("Naphtol AS-PH" dye precursor).
Alizarin is the main ingredient for the manufacture of the madder lake pigments known to painters as rose madder and alizarin crimson. Alizarin in the most common usage of the term has a deep red color, but the term is also part of the name for several related non-red dyes, such as Alizarine Cyanine Green and Alizarine Brilliant Blue.
Genuine vermilion pigment today comes mostly from China; it is a synthetic mercuric sulfide, labeled on paint tubes as PR-106 (Red Pigment 106). The synthetic pigment is of higher quality than vermilion made from ground cinnabar, which has many impurities. The pigment is very toxic, and should be used with great care. [16]
