Basically, glue!. The binder holds the pigment, or carries it, which is why it's also called a vehicle!. When exposed to air the binder, or binding medium, dries, leaving the pigment on the surface where it was applied!.

Acrylic paints use a polyvinyl acetate medium, which dries by evaporation!. This is why they look flatter when dry!. Oil paints have the pigments suspended in oil, which dries by oxidation (it reacts with oxygen) which is why they dry more slowly but don't contract!.Www@QuestionHome@Com
