Organic coatings are generally utilized to improve dispersability and flow characteristics of titania pigments. A fascinating array of substances are either used commercially or have been claimed as useful in the patent literature [6], Organics held in place simply by electrostatic forces [7] as well as those cemented to the surface by use of covalent bonds are known [8], The latter are inert to diffusion through the polymer matrix. Said diffusion can lead to end-use problems that include such phenomena as loss of low-temperature heat seal and poor printability. 

Rare earths are used in the paints and pigments industry (i) as coating materials for pigments to enhance their durability and performance characteristics, (ii) in the manufacture of ceramic pigments and (iii) in the manufacture of driers for organic coatings. 

Blue pigments. The most common organic blue pigments in the coating industry is copper phthalocyanine (Fig. 7.11) [10]. This is a bright,...
