Printing ink applications

Epidemiological and Human Dosimetry Studies. The potential for occupational exposure exists in the use of 3,3 -dichlorobenzidine in the synthesis of 3,3 -dichlorobenzidine-based pigments for printing ink applications and to a lesser extent in paints. Workers exposed to 3,3 -dichlorobenzidine (and simultaneously to other chemicals) have complained of gastrointestinal upset, upper respiratory infection. 

The bland taste of rice starch, its whiteness and its small granule size have provided it with the advantages necessary in the manufacture of smooth gravies, sauces and puddings, having excellent mouthfeel and flavor profiles. Non-food uses of rice starch are also based on its small granule size they include textile size, cosmetic and printing ink applications.

For printing ink application, however, their very high opacity could be of interest in certain specialty applications. 

One-half of the MEK produced is used as a solvent by the coatings industry. It is also used as a chemical intermediate. MEK is also used in printing ink applications. 

Industrial nonfood applications are as foundry core binders, as stabilizers for drilling muds ( oil-field chemicals), as components in glue mixtures, in the processing of paper and cardboard, as carrier for water in soluble colors and printing inks. Applications in food industries are for convenience foods, such as sauces, puddings, custards, filling creams, flour blends for cake and cookies. 

Other Applications. PEO has also been used as an antistat additive (178,179), water-soluble packaging material of seeds and fertilizers (180), and rheology modifier in aqueous flexographic printing inks (qv) (181). 

Nonfood Uses. Vegetable oils are utilized in a variety of nonedible applications, but only a few percent of the U.S. soybean oil production is used for such products (see Table 13). Soybean oil is converted into alkyd resins (qv) for protective coatings, plasticizers, dimer acids, surfactants (qv), printing inks, SoyDiesel fuel (methyl esters used to replace petroleum-based diesel fuel) and other products (76). 

Other applications of spirooxazine compounds include toys, cosmetics, printing inks, and clothes. 

Prussian blue (PB ferric ferrocyanide, or iron(III) hexacyanoferrate(II)) was first made by Diesbach in Berlin in 1704.88 It is extensively used as a pigment in the formulation of paints, lacquers, and printing inks.89,90 Since the first report91 in 1978 of the electrochemistry of PB films, numerous studies concerning the electrochemistry of PB and related analogs have been made,92 with proposed applications in electrochromism1 and electrochemical sensing and catalysis 93... 

Carbon blacks are principally made by the chemical decomposition of natural gas or oil. Two classes predominate the furnace blacks (95% of black usage) which are active, and thermal blacks (5% of usage) which are inactive. There are a substantial number of blacks for special applications such as electrically conducting and printing ink blacks. The latter are of too fine a particle size for rubber use. The nomenclature used for carbon blacks includes the ASTM designation and the industry type as illustrated in the next table.
