Drying of a colloidal droplet on solid surface leaves a ring like deposits. The deposition pattern depends on the fluid flow inside the droplet during drying process. The 3D flow field inside the droplet of pinned contact line is reported using micro-PIV technique. Fluid flow towards the contact line is observed to be responsible for the ring like deposition pattern. The magnitude of the velocity is observed to be more near the contact line.
