[Class 95] A water colour, particularly for use in painting on photographic prints, comprises a watersoluble dye, gum arabic, oxgall, glycerine and water, mixed into a paste.

The paste may be filled into a container with a sealed opening, or it may be dried out in a tray, to form a sheet which can be cut up into pieces for fitting into the usual pans of paint boxes.
