Pigmented inks

Emulsion—Suspension Polymerized Pigment Ink. Polymerization of a polar prepolymer as the internal phase in an oil-based external phase (24) gives a fluorescent ink base in which spherical fluorescent particles are dispersed. This base is suitable for Htho and letterpress inks (qv). An...

PCBs are synthetic chemicals that exist as oils or waxy substances they do not occur naturally. They were once used in many products including hydraulic fluids, pigments, inks, plasticizers, lubricants, and heat transfer fluids, but their primary use was as a dielectric fluid in electrical equipment. Because of their high thermal stability, chemical stability, and electrical insulating properties, PCB fluids were used extensively in transformers, fluorescent light...

Isohexides exhibit excellent properties as plasticizers for polyvinyl alcohol polymers.2 Compounds obtained from isosorbide and trialkylaluminum proved to be highly active cocatalysts for polymerization of alkenes. Such derivatives, which were supposed to be oligomeric O-aluminum-isosorbides, are of glass-like appearance and exhibit pyrophoric properties.255 Isosorbide is a component of mixtures used for water-based pigment inks, having excellent dispersion stability, which is necessary for ink-jet printing.256 257...

Conventional water-based and non-aqueous inkjet inks are mixtures of several components, including volatile solvents, dissolved materials, and dispersed solids (for pigment inks). When the ink reaches the nozzles prior to jetting, the volatile components may evaporate from the nozzle. Therefore, the liquid in the vicinity of the nozzle can have a composition which differs from that of the bulk ink which is further back in the print head supply channels. This disparity causes differences in the physicochemical properties of the ink (e.g., an increase in viscosity or decrease in surface tension)... 

The major advantage of the microporous coatings is the speed with which they absorb inks as a result of their porosity. This instantaneous absorption provides, in effect, instant drying. Additional characteristics of the microporous layer are the high water fastness and its compatibility with both dye and pigment inks. 

Since the PS reference sample is almost monodisperse, a cumulant analysis of that material would yield a very small Q, say Q < 0.03. That is, all the correction terms are negligible and Eqs. (17) collapse to Eqs. (12). But cumulant analysis is a useful way to handle practical samples such as pigments, inks, microemulsions, swollen micelles, globular proteins, and spherical virus particles, where there is a size distribution but one that is not very broad (say Q < 0.3). This analysis should be made for the milk data using a non-linem teast-squares fitting of Eq. (17a), neglecting /1.3 and all higher order terms. Report the F, D, and R values as well as the second cumulant /t2 aiid the polydispersity index Q. 

Short drying time is a particular advantage with heat sensitive materials. Porosity and small size are desirable when the material subsequently is to be dissolved (as foods or detergents) or dispersed (as pigments, inks, etc.). Table 9.17 has some data on size distributions, bulk density, and power requirements of the several types of atomizers. 

Applications of this process at an industrial scale have been in the area of removal of light colloidal systems such as emulsified oil, ions, pigments, ink, and fibers from water (36,37). The advantages of this process are the clarity of the treated wastewater and the disadvantages are the low throughput, the emission of H2 bubbles, electrode costs and maintenance, and the voluminous sludge produced (24). 

Use Reagent in analytical chemistry, aniline black, textile mordant, enamels, chromate pigments, inks.
