    The invention relates to 1. A method of irreversibly coloring a coating composition containing a color former comprising the steps of a) providing a coating composition that consists of an UV curable resin, a thermosetting resin or an alkyd resin; b) mixing the coating composition with the color former whereby no color is formed; c) applying the colorless composition obtained in step b) to a substrate; d) in case of a thermosetting resin curing the resin between 100 and 300 DEG C, preferably between 100 and 150 DEG C, whereby no color is formed, in case of alkyd resin drying of the resin at room temperature, whereby no color is formed; e) exposure to UV or high energy radiation below 400nm whereby the color is formed.
