Transparent functional pigments do not have any “color properties” in the visible light range. Their main field of application is based on their ability to absorb UV radiation. They can be used to protect organic materials such as plastics and coating resins as well as human skin (in the form of sun-creams). However, care must be taken when using these pigments, because the large surface area of the particles increases their reactivity. Figure 5.42 shows the dependence of the light scattering of anatase pigments on particle size. Primary particles <ca. 25 nm do not scatter light [5.194].
