Pigment

From PaperWiki
Jump to: navigation, search

A pigment is an insoluble material which can be added to pulp before it is formed into paper. White pigments boost brightness and opacity; coloured pigments and dyes control the shade or change the colour.

Pigments when added to pulp are more often referred to as filler.

The term pigment is more often used when this type of material is used in pigmented coatings or for colouring materials.
