Abstract
A method for producing images () on a substrate () with colour bodies thereon, the colour bodies losing a colour effect due to a laser () and consisting of dyes or pigments contained in capsules (). Different colour bodies having at least three different colour effects are on or in the substrate (). The method includes: (a) producing a colour chart (), with individual colour effect of individual colour bodies contained as a function of the spatial coordinates thereof on or in the substrate; and (b) spatially resolving radiation, which opens the colour effect of colour bodies of individual capsules and releases dyes by a laser () at a single frequency on the basis of the colour chart () in order to produce a resultant colour effect. Substrates, like security documents, can be produced this method.
