The substance, IUPAC name (29H,31H-phthalocyaninato(2−)-N29,N30,N31,N32)copper(II), is known by many names [2] such as monastral blue, phthalo blue, helio blue, [3] thalo blue, Winsor blue, [4] phthalocyanine blue, C.I. Pigment Blue 15:2, [5] [6] copper phthalocyanine blue, [7] copper tetrabenzoporphyrazine, [8] Cu-phthaloblue, [9] P.B.15.2, [10] [11] [12] C.I. 74160, [13] [14] [15] and ...
Chemical structure of copper phthalocyanine. Copper phthalocyanine ("phthalo blue") is a synthetic blue pigment frequently used in paints, inks, and dyes. It is highly valued for its superior properties such as light fastness, tinting strength, covering power and resistance to the effects of alkalis and acids. It has the appearance of a blue ...
The Monstral blue found to coat the inside of copper vessels used to process phthalic acid derivatives had led to the discovery of Phthalocyanine in 1907. Attracted by the brilliance, stability and insolubility of this chromophore, attempts were made to reversibly modify it so that it would be carried into fabric in a solution and then easily precipitated (ingrained) into an unleachable but ...
Phthalocyanine (H 2 Pc) is a large, aromatic, macrocyclic, organic compound with the formula (C 8 H 4 N 2) 4 H 2 and is of theoretical or specialized interest in chemical dyes and photoelectricity. It is composed of four isoindole units [ a ] linked by a ring of nitrogen atoms.
Copper phthalocyanine; Aluminosilicate pigments. Ultramarine (PB29): a synthetic or naturally occurring sulfur containing silicate mineral - Na 8–10 Al 6 Si 6 O 24 S 2–4 (generalized formula) Persian blue: made by grinding up the mineral Lapis lazuli.
[12] [13] Azurite (Cu 3 (CO 3) 2 (OH) 2) is a soft, deep-blue copper mineral produced by weathering copper ore deposits; it was used since ancient times and was first recorded by the first century Roman writer Pliny the Elder. [14] Phthalocyanine Blue BN was first prepared in 1927 and has wide range of applications.
For example, Phthalocyanine Blue BN has been known by a variety of generic and proprietary names since its discovery in the 1930s. In much of Europe, phthalocyanine blue is better known as Helio Blue, or by a proprietary name such as Winsor Blue. An American paint manufacturer, Grumbacher, registered an alternate spelling (Thanos Blue) as a ...
Luxol fast blue stain, abbreviated LFB stain or simply LFB, is a commonly used stain to observe myelin under light microscopy, first developed by Heinrich Klüver and Elizabeth Barrera in 1953. [1] Luxol fast blue refers to one of a group of three chemically and histologically similar dyes.
