Pigments, paper

In recent years, synthetic polymeric pigments have been promoted as fillers for paper. Pigments that ate based on polystyrene [9003-53-6] latexes and on highly cross-linked urea—formaldehyde resins have been evaluated for this appHcation. These synthetic pigments are less dense than mineral fillers and could be used to produce lightweight grades of paper, but their use has been limited in the United States.

Analytical chemists work routinely with dyes even if they are unaware of it. Most acid-base indicators are dyes, as are a number of products of presumptive tests discussed in Chapter 7. Histological stains used in biological disciplines are also dyes. As mentioned, dyes are oiganic compounds that are soluble in the media they are contained in (such as ink or paint). Dyes also have an affinity for the substrate they are being placed on (such as paper). Pigments, by contrast, are typically metallics or organometalUcs that contain a...
