Novel Deep-Eutectic Solvent (DES) / Linseed Oil Paint

 I use a 1:2 mol ratio of choline chloride: urea.  I heat the mixture for 30 minutes at 80 deg C until a clear liquid forms.  Cool to room temperature before use.

I place a  few drops of dye ( yellow food coloring is shown here) in  2 ml. of the DES.  I then add 1-2 ml of boiled linseed oil and stir well.

It seems the linseed oil is forming a micro-dispersion in the DES/dye. it applies beautifully to poster-board  or wood.  It will dry over 30 minutes to the touch.  No odor. The DES/linseed oil will not change over 2-3 days at 20 deg in an open beaker.
