The correct statement among the options provided is:
a. A pigment is a colorant that forms direct bonds with a surface.
Explanation:
- A pigment is a colorant that is insoluble in the medium in which it is used (such as paint or ink). Pigments are typically suspended in a binder (like oil, acrylic, or water) to create a paint or ink.
- Pigments do not form direct bonds with a surface but are instead held in place by the binder once the medium dries or sets.
- Dyes, on the other hand, are colorants that dissolve in a medium (like water or other solvents) and form direct bonds with the surface of the material they are applied to.
- Paint is a mixture of pigments and a binder, applied to surfaces to provide color and protection, but the pigments themselves do not form direct bonds with the surface.
