It can be soothed with a little Umber or Black when it is too bright in a landscape painting. The extensive delocalization of the π-electrons affords the molecule useful properties, lending itself to applications in dyes and pigments. Developed by chemists using the trade name Monastral Blue, the organic blue dyestuff now known as Phthalo Blue was presented as a pigment in November 1935 in London. B690 Phthalo Blue Turqoise. History of the Colors Phthalo Blue and Ultramarine, Real and Synthetic. There are other phthalocyanine colors as well, which are equally lightfast. Phthalo blue is a pigment you’ve seen thousands of times before, but maybe not had a name to put to the color – it’s the sea, the sky, and in the case of Bob Ross, snowy accents in paintings. The legendary painter working on a landscape — note the snowy hues. Pure copper phthaliocyanine in crystalline form is a deep blue with a strong bronze reflection, but when dry in pigment form is bright blue without any bronziness. Available: in 60 ml tube. Marion Boddy-Evans is an artist living on the Isle of Skye, Scotland. H2Pc has a two-dimensional geometry and a ring system consisting of 18 π-electrons. Lexico's first Word of the Year! How to say phthalo in English?

The color was presented as a pigment in London in November 1935. [12] Using such methods, approximately 57,000 tonnes (63,000 tons) of various phthalocyanines were produced in 1985.[12]. SCROLL DOWN FOR REVIEWS . [5] They are less thermally stable and often can not be sublimed. PB15:3-Phthalo Blue. At the initial discovery of Pc, its uses were primarily limited to dyes and pigments. B688 Old Holland Blue Grey. In the same year, iron phthalocyanine was discovered at Scottish Dyes of Grangemouth, Scotland (later ICI). Marion Boddy-Evans. Phthalocyanine Blue BN, also called monastral blue, phthalo blue (and others) (CAS 147-14-8, EINECS 205-685-1), is a bright, greenish-blue crystalline synthetic blue pigment from the … History. [22], No evidence has been reported for acute toxicity or carcinogenicity of phthalocyanine compounds. Join Facebook to connect with Phthalo Blue and others you may know. There are many derivatives of the parent phthalocyanine, where either carbon atoms of the macrocycle are exchanged for nitrogen atoms or the peripheral hydrogen atoms are substituted by functional groups like halogens, hydroxyl, amine, alkyl, aryl, thiol, alkoxy and nitrosyl groups. Each watercolor manufacturer often produces multiple Phthalo blue colors, and these are commonly divided by whether they have a green … Phthalocyanine Blue (Copper Free) is the greenest shade of Phthalo Blue, and possesses the high resistance properties of other Phthalo Blue pigments, although it tends to be less heat resistant than other versions. Origin. They're lightfast, and an ideal pure blue for it absorbs light almost completely except for the green and blue bands. They remarked on the enormous stability of these complexes but did not further characterize them. Straight from the tube, both of these pigments look nearly identical to phthalo when it’s been lightened with white. Love. Serie: C. Pigment classification: PB 16.
