One party of powdered lecithin was wet with two -three parts of water. The mixture is stirred well after five minutes at 20 deg C. An equal amount of a commercial watercolor paint (tube) is added and the mixtures stirred to a creamy texture.
At this paint, 1-2 drops of dammar resin ( 20% m/v) in linseed oil is added and the mixture stirred well. The paint flowed well of the brush and applied to bristol paper directly. The paint became dry to the touch after one houer at 20 deg C.
