1- Azo Dyes for Stylastar Particles:

Les pigments azoiques of acetyllacetarylides,

This group includes azo dyes to which the Estela star-lead part is attached, all of which are yellow and are divided into three categories: (1) Les jaunes Hansa yellow of all kinds, all of which are greenish-yellow or reddish dyes, which are very solid in light and heat and are used in the colors of refractory enamels that are made in ovens, but it disintegrates in some organic solvents.

Les jaunes de benzidine.

(b) Benzidine dyes tend to orange, and are less solid in light than Hansa yellow and more solid in heat and insoluble in all organic liquids

And it's yellow

(C) Les jaunes de bis second dyes Estella Seto yellow, which is the same as the previous one, and in the light like Hansa yellow dyes, heat and solvent resistant benzidine dyes. acetyllacetobenzidide

Les pigments azoïques de pyrazolones

Azopyrazolone dyes

Azo dyes include yellow, orange, and red and are sometimes called Hansa yellow. It is of light molecular weight, so it is less valuable than the original Hansa yellow, orange and red dyes, which are solid in light and do not disintegrate in solvents.

- Lacquer and Azobeta Na-Ftol dyes

Les laques and pigments azoïques du B-naphtol

This group includes red and orange dyes and is divided into two categories: (1) Dyes from compounds derived from diazos d'amines non sulfonées, which are neutral dyes that resist water, acids and alkalis, but they disintegrate to a greater or lesser extent in oils and organic solvents due to their low molecular weight. The oldest member of this group is red para rouge para, and its color is vivid red, turning to orange or violet. It is solid in light, but disintegrates in oils and all organic solvents.. Hence it is preferred to be used in emulsion paints. There is a chlorine derivative and another nitrogenous one, which are yellowish in color and more solid in light, and disintegrate to a lesser extent in oils and hydrocarbons. Finally, he built the bara brun para, which is a copper compound of the red bara, its color is like chocolate, and its coloring ability is high. It is also very solid in light and solvents, but it is highly flammable when dry. nitres

Rouge de toluidine is a vivid red color dye with many shades, very hard in light, and does not dissolve in oils or aerosols.
Carbonate. It is frequently used in oil paints and fatty varnishes, but it is less used in enamels inside peers because it evaporates at high temperatures.

(b) tension les toners (which are calcium and barium salts) for the acidic colorants derived from diazamines sulfonées de colorants acides dérives de dinzos d'amines sulfonées, which are insoluble in oils and hydrocarbons that have little solubility in alcohol and are hydrolyzed by alkalis, their hardness is weak or medium in light due to the presence of a group (Cap a acid) in it, the most important of which is lithol red, which turns to orange or violet, and red lacquer (C) and its coloring ability is high, and it is more resistant to heat, but it is more expensive than orange

- Azo dyes derived from beta-oxynaphtoic acid.

rubis lithol and calcium, barium and manganese salts have pigments close to red lyol and their colors are flatter and more solid in light, and they are insoluble in oils and all organic solvents, and are used in oil paints, fatty varnishes, glyceric, phthalic and cellulosic lacquers, but they are sensitive to alkali. The most important of which are ruby ​​liol, permanent red or fixed red 2-b - rouge permanent) and marrons-toners glycerophtaliques rubis Lithol

E - Azobeta oxyniftarilide dyes

The pigments are azoïques of B-oxynaphtarylides

It includes red pigments of different colors, some of which tend to violet, and all of them are solid in light and heat, and are used for Duco car paints. Likewise, almost all of them are neutral, do not dissolve directly in water, and are not affected by acids or alkalis. Therefore, they are used in emulsion-shaped coatings, which are insoluble in oils and hydrocarbons, and can be brushed on a large area, including fixed red, naphtol reds, and toluidine bordeaux. ) and stable carmine red, red and bordeaux, and chromophthal violet, the latter being solid in heat and solvents. Bordeaux carmins cromophtal

- Azo compounds of naphtosulfonic acids

Les azoïques des acides naphtosulphoniques

They are orange, red and Bordeaux acids, and their salts of calcium and barium are used as insoluble in water or as tension dyes. They do not disintegrate in organic liquids and are generally of little hardness in light and alkalis. And in cellulosic lacquers, glycer, and glycerophtaliques
Only ponceau de slidine red, ecaclate-pigment 3 B, and Helio Bordeaux toner are used, and their hardness is reasonable to light. Its hardness is reasonable to light

- Lactate, anthraquinone and indigo dyes

Les laques et pigments anthraquinones et indigoïdes

d'alizarine (a) the colored lacs of the anther aquinone) for the red alizarine laque rouge and for the violet alizarine J..etc. It is based on aluminium (aluminum oxide), which is usually used in printing inks, cellulosic lacquers, and glycers. It is consistent with its hardness in light and organic liquids, despite its weak color.

anthraquinones

indanthrone (b) indanthrone dyes (neutral dyes that do not dissolve directly) and the oldest and most important of them is indanthrone, and their colors vary greatly, but they are often alive, and their ability to color is weak. They are used in car duo due to their hardness in light and heat, their resistance to acids and alkalis, and their insolubility in water, oils and organic solvents.. However, their prices are high, the most important of which are: flavanthrone (yellow) and bromine derivatives of pyranthrone, as well as anthan throne and its halogen derivatives flavanthrone

All neutral dyes derived from antherquinone and indigo, and some water-soluble lacquers derived from anthraquinone, include:

(orange) and anthrones (blue)..etc

(c) Indigo dyes, their general characteristics and trade names are similar to the above, and they are halogen derivatives (chlorine, bromine, and iodine) and methyl indigo. They are pink, red, and violet dyes with vivid colors and are used in emulsion paints and enamel coatings.

thioindigo sulfur

l'indanthrone

sulfonés phtalocyanine de cuivre, which are its metallic compounds, especially copper, and its chlorine and sulphonic derivatives, all of which are blue and green dyes that are solid in light, heat, chemical agents, and solvents. Copper lucyanin is a blue-reddish or greenish dye, and its coloring ability is high, and it is very hard in light and heat (up to 5600 C), and it is resistant to chemical agents, acids, alkalis, and proven and stored materials, and it is insoluble in water and organic liquids. It can replace Prussian blue and sky blue in all kinds of paints

Phtalocyanins

Phtalocyanine de cuivre chlorée is an emerald green pigment that has the same properties as the above.
