Deep Eutectic Solvents (DESs) are essentially non-volatile. I am developing dye paint formulations using them. The own shown has a biochemical DES , PVP polymer ( polyvinylpyrrolidinone) , yellow food coloring and a very small ammoiunt of water. The paint is homogeneous and applied to poster-board.
The paint can be left open to the air and only the water will evaporate. More water can be added , if desired. The PVP will form a thin film. The paint has no odor. Uniform application is being observed.
This is under development. I want to see if UV radiation will occur with dyes under these conditions.
One coat applied to poster board/ let dry 30 minutes ( 20 deg C) and apply a second coat.
