4. WHAT IS PAINT?
Any pigmented liquid that is liquefiable, or
solid mastic composition that, converts to a
solid film after its application in thin layers
to a substrate. Its main purpose is to protect,
color or provide texture.

5. COMPOSITION OF PAINT
There are 4 main components of paint:
 Pigment;

6. Remnants of paint from a
crime scene can reveal a
significant amount of
information upon
subjecting to forensic
analysis. Paint is generally
transferred as a trace
evidence from accused to
the crime scene or victim’s
body. It can be used
purposely to form a link
between the accused or the
suspect to the crime scene.
