Applications for Printing Inks

In the United States, approximately two-thirds of flexographic ink is water based one-third is solvent based in an estimated flejrographic ink market of 200000 tons. The major volume of water based flexo ink consumed in the United States is for printing corrugated containers. The total US ink market for all six printing processes Hsted above is estimated at over 1.1 million tons for year 2000 or approximately 4.5 bilHon US. 

In Latin America less than one-third of flexographic ink is water greater than two-thirds solvent based in an estimated flexographic ink market of 34 000 tons. The total Latin American ink market for aU printing processes is over 125 000 tons for year 2000 or approximately 750 million US.

P.Y.97 is used in a variety of fields. Even in pastel shades, it is used in industrial finishes while its full shades lend color to automobile refinishes. In emulsion paints, both its medium and full shades are suited to exterior application. The printing ink industry uses P.Y.97 in high grade printing products, especially where excellent fastness is required, such as in stable posters, etc. It lends itself without difficulty to all printing techniques. However, lack of fastness to monostyrene and acetone and therefore a certain tendency to bleed in these media precludes its application in deco printing inks, i.e., for decorative laminates. 

P.O.67 is also recommended for printing inks, especially for flexo inks on NC base. Special pigment preparations for this application are on the market. 

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. 

Of the 10% of carbon black used for nonrubber applications, about 35% is used for plastics, 30% for printing inks, 10% coating, and 5% for paper. In plastics, carbon black... 

Present usage of triarylmethane dyes, ca 1996, is confined mainly to nontextile applications. Substantial quantities are used in the preparation of oiganic pigments for printing inks, pastes, and for the paper printing trade, where cost and brilliance of shade are more important than lightfastness. 

For a wide range of applications, however, chloride and sulfate pigments are exchangeable and for various appUcations sulfate pigments may offer superior properties (e. g. for printing inks due to the less abrasive character of sulfate pigments). 

Additive used for thermoplastic applications requiring lubrication, slip and anti-blocking properties. Commonly used in polyethylene and polypropylene films, as a lubricant in polyvinyl chloride, mold release agent, dyestuff dispersant for printing inks and surface coatings, and a blending agent for polyamide resins. 

In industrial applications liquid fatty acid esters are well known as plasticizers for pyroxyline varnishes and as secondary plasticizers for PVC. They are used as thinners and carrier oils and have become established as green solvents (see Chapter 10) for printing inks (Table 9.1.9) and for industrial surface cleaning due to their low volatility, environmental compatibility and contribution to work hygiene and industrial safety. ...

The Cg, Cio and C12 dibasic acids, as their butyl, hexyl, 2-ethylhexyl and octyl esters, are used as plasticizers for PVC, as engine lubricants and as intermediates in the production of polyamides, polyesters and polyurethane adhesives, coatings, fibres, inks and resins. The C2i-diacid is used primarily as a surfactant. By condensation with diamines, dimer acids are used extensively to furnish polyamide resins. Their major applications are printing inks, hot-melt adhesives and coatings. Reactive polyamides are used as curing agents for epoxy resins.
