Paper coatings impart a variety of properties, both decorative (whiteness, opacity, etc.) and functional (smoothness, absorption rate, etc.). A typical coating has two principal constituents: a dispersion of pigments in water and an adhesive or binder.

Traditionally coatings were based on clays such as China clay (kaolin) and bentonite, however, in modern paper coatings calcium carbonate is more common. Other materials are also used to obtain certain properties. These include:

Talc - for smoothness.

Silica - for applications requiring good water absorption rate - e.g. ink jet paper.

Titanium dioxide - for whiteness and opacity.

Resins - control of ink absorption rate.
