A limitation in using bismuth vanadate is the care needed in dispersing the pigment. As with other silica-encapsulated pigments, even partial shearing of the encapsulant will noticeably diminish thermal stability and durability. [Pg.137]

ITRI has developed and patented processes for preparing and utilizing stable aqueous colloidal sols of tin(IV) oxide and related materials. These products, which contain nanometer-scale particulate tin oxide, are useful precursors for the synthesis of ceramic bodies, powders, and coatings, and may And application in encapsulated pigments, electroconductive materials, catalysts, and transparent tin oxide Aims on glass and other substrates.

Some encapsulation methods of polymer-encapsulated pigments often do not perform well for thermal inkjet inks. A common method involves capsules formed with dissolved polymers that are adsorbed onto the pigment surface. [Pg.129]

Since the dissolved polymers are usually not crossUnked, the pol nner surfaces of such known encapsulated pigments t5rpically agglomerate under the high thermal shear and solvent conditions of the pen firing chamber, causing nozzle and ink channel blockages. [Pg.129]

Pol mer-encapsulated pigments are made by the polymerization at the surface of the pigment using a plurality of acidic monomers (20), cf. Table 4.4 and Figure 4.2. [Pg.129]

As mentioned previously, polymer-encapsulated pigments are of major implication in the coating industry and, consequently, a variety of monomers have been used to produce the shell, including vinyl acetate as well as combinations of vinyl acetate, isobutyl acrylate, styrene, -butyl acrylate, methyl methacrylate, acrylonitrile, and...
