Artists Colors

This traditional use for ultramarine in all types of media is still an important application. Unique color properties, stability, and safety are highly prized. 

Ultramarine pigments are widely used in plastics and surface coatings for toys, children s paints and finger paints, modeling compositions, colored paper, crayons etc. They comply with major regulations and standards.

Ultramarine pigments ate used in printing inks, textiles, mbber, artists colors, cosmetics, and laundry bluing. Because of their thermal stabiHty they are also used to color roofing granules.

Good overall fastness and considerable tinctorial strength broaden the scope of P.Y.83 application. The list includes office articles, artists colors, and solvent-based wood stains, in which the pigment is frequently combined with red pigments and carbon black to produce shades of brown. 

Naphthol pigments are broad in scope in many fields. Special applications include cleaners and detergents, office articles, and artists colors, as well as match-head compositions and fertilizers. 

Naphthol AS pigments are used to an appreciable extent in special areas, such as in office articles, artists colors, cleaning agents and detergents, including soaps. They are used to color paper, both mass colored paper and surface coated paper. 

P.R.8 is used in a variety of special media outside the paints, printing inks, and plastics field, which is also true for other members of this class of pigments. One such application is in the paper industry, where the pigment is used for mass coloration and surface coating formulations. It also lends itself to application in artists colors and office articles. 

P.R.10 is used to a certain extent in office articles, artists colors, and cleaners. 

The paint industry employs P.R.22 in air drying systems, in emulsion paints, and occasionally in industrial finishes although there is some danger of blooming, and the appropriate limit has to be observed. Again, P.R.22 is much less lightfast in these media than P.R.l 12. Areas of application include paper mass and surface coloration, colored pencils, artists colors, and other purposes. 

P.R.146 is a suitable candidate for a variety of special applications. The list includes wood stains, in which it is frequently blended with yellow pigments, especially with P.Y.83, and also with black to afford shades of brown. The products are fast to overcoating and stable to nitro and acid catalyzed and polyester varnishes. Intense shades match step 5 on the Blue Scale for lightfastness. Other areas of application include office articles and artists colors, cleaning agents, paper mass coloration, laundry markers, etc. In connection with cosmetics, the pigment frequently lends color to soaps. 

P.O.38 is broad in scope. The list of applications includes special media, such as wax crayons, artists colors, and wood stains, including those that are solvent based. The products are very lightfast (step 7 on the Blue Scale) and fast to overcoating. Blends of P.O.38 with yellow pigments, such as P.Y.83 or P.Y.120, or with carbon black produce useful shades of brown. 

An important application of P.Gr.8 is in the coloration of rubber. The pigment, however, is not suitable for use in blends which contain large amounts of basic fillers. It is somewhat sensitive to cold vulcanization. The colored articles usually perform well in general application but are not entirely fast to aromatic hydrocarbons and to some fats, and they are sensitive to acid and sulfur dioxide. P.Gr.8 also colors some plastics, especially LDPE and polystyrene. Heat stable up to 220°C, P.Gr.8 grades equal step 2-3 on the Blue Scale for lightfastness. Other areas of application include wallpaper and artists colors. 

P.R.89 affords a very bluish shade of red, referred to as pink. It exhibits good tinctorial strength and good lightfastness. Full shades in a combination nitro lacquer, for instance, equal step 7-8 on the Blue Scale. Somewhat poor overall fastness restricts the applicability of P.R.89. The pigment was considered a spe-cialpurpose product for artists colors. It used to be employed also in spin dyeing viscose products. 

P.R.83, listed under Constitution No. 58000 1, continues to be used only in the USA. The pigment affords brilliant, bluish shades of red. Traces of iron as an impurity adversely affect the full shades and shift the color towards duller and bluer shades. The pigment is not fast to common organic solvents, especially to esters and ketones. It therefore lacks stability to overcoating. Its lightfastness, particularly in tint, is poor. P.R.83 is used in paints for toys, in packaging printing inks, especially for soap and butter, and in artists colors. 

P.Y.24 is also sold for use in other areas in which high lightfastness is a prime concern. It is thus used in media such as solvent-based wood stains and in artists colors. 

There are a number of other media which are also pigmented with P.V.23. The list includes office articles and artists colors, such as drawing inks and fiber-tip pen inks, wax crayons, oil paints, and high quality water colors, water- or solvent-based pigmented wood stains, cleaning agents, and mass colored paper. 

Prussian blue, in the form of printers inks, artists colors, and paints, soon flooded the market. It also stimulated interest in other potentially useful substances that might be derived from the potash, iron, and animal-residue mixtures. One of these, known as red prussiate of potash, did turn out to be very useful. When combined with ferric ions, it didn t produce a dramatic color until it was exposed to direct sunlight. Then it turned blue. Prussian blue. The discovery revolutionized archi-... 

Uses. The most important areas of use of pigments are paints, varnishes, plastics, artists colors, printing inks for paper and textiles, leather decoration, building materials (cement, renderings, concrete bricks and tiles—mostly based on iron oxide and chromium oxide pigments), leather imitates, floor coverings, rubber, paper, cosmetics, ceramic glazes, and enamels. 

The use in coating media is also.prohibited since 01.01.96. Use in artists colors and ceramic products is still permitted. 

Cinnabar, or vermilion (sp. gr. 7.5 to 8.1), is the stable modification of mercuric sulfide at all temperatures up to its sublimation point (about 580°C.). Its chemical properties are about the same as those of the black modification, and its stability makes it useful as a pigment for artists colors.

Cd and its compounds find applications in several industrial materials electrode materials in Ni-Cd batteries (about 70% of total produced Cd), pigments in ceramics, glasses, paper, plastics, artists colors (13%), stabilizers for polyvinyl chloride and related polymers (7%), coatings on steel, aluminium, and other nonferrous metals (8%), and specialized alloys (see Alloys) and others (2%).
