The invention relates to a card-shaped data carrier consisting of at least one layer (). Visually readable information in the form of a changed optical characteristic is introduced into the layer. Said characteristic is changed by irreversibly changing the material by means of a laser beam. The absorption capacity of said layer () for at least one wavelength (&#x3bb;&#xb1;&#x3bb;) is at least partially reduced due to the laser radiation.

Card-shaped data carrier and method for producing same

A description is given of a method for applying colored information to an object (), the object having at least two different chromophoric particles, at least in a layer (A) close to the surface, which change the color of this layer (A) under the influence of laser radiation, According to the invention, at least one beam guiding means () is provided in order to guide a first laser beam () having the wavelength (&#x3bb;) and at least one further laser beam () having a wavelength (&#x3bb;), which is different from the wavelength of the first laser beam, via the two-coordinate beam deflection device () and the focusing device () onto the layer (A) of the object ().

Method for applying colored information on an object

The invention relates especially to a method for producing a product that is secure against fraud, i.e. a security product. The inventive method for producing a security product with a high degree of protection against fraud or tampering is characterized as follows: in a first step, a non-personalized and/or non-individualized support is provided with a non-personalized and/or non-individualized security element ( ); in a second step and/or in further steps, the non-personalized and/or non-individualized support and the non-personalized and/or non-individualized security element ( ) are personalized and/or individualized; a structure ( ) that is optically effective in the security element ( ) produces at least two especially, color effects; at least one of the color effects ( ) only appears within a certain angular range to a vertical to the surface of the security element, and a personalizable and/or individualizable layer ( ) that is provided in the security element ( ) and/or a personalized and/or individualized layer that is provided in the security element ( ) shows personalization and/or individualization information.
