LASER POST-TREATMENT OF METAL EFFECT PIGMENT SURFACES TO LOCALLY INCREASE RADAR AND/ OR LIGHT TRANSMISSION
Post-treatment method and/or fine patterning method of effect pigment-containing or metal-containing particle-containing objects, for example car body parts or cosmetic containers or layers, for example paint layers or printing ink layers, by means of energy input (e.g. heat input, preferably by laser light), whereby the hiding power of metal-containing pigment platelets or metal-containing particles is permanently reduced by their change in shape factor. In the treated surfaces, this change in shape factor causes a permanent local increase in transparency, translucency or transmission for electromagnetic waves, in particular radar wave, radio wave and/or light wave transmission, and/or a local reduction in reflectance, for example for the production of painted radomes. The process differs from conventional laser marking in that the transmission for electromagnetic waves of normally reflective metal-effect pigment surfaces or metal-containing particles is permanently increased by the change in shape factor caused by the laser beam, whereby pigment platelets or particles are changed either by direct melting and/or by triggering an auxiliary chemical reaction in such a way that their metal core is at least partially melted, possibly chemically transformed and/or destroyed.

LASER POST TREATMENT OF METAL EFFECT PIGMENT SURFACES FOR LOCALLY INCREASING RADAR AND/OR LIGHT TRANSMISSION
The invention relates to a post treatment method and/or fine pattern method for objects containing effect pigments or metallic particles, such as car body parts or cosmetic containers or coatings, such as varnish coatings or printing ink coatings, by means of energy input (heat input, for example, preferably using laser light), wherein the covering power of pigment platelets or particles containing metal is permanently reduced by the form factor alteration thereof.

The method differs from conventional laser marking in which the transmission for electromagnetic waves from normally reflecting metal effect pigment surfaces or particles containing metal is permanently increased by the form factor alteration caused by the laser beam, wherein pigment platelets or particles are altered either by direct melting and/or by triggering a chemical auxiliary reaction such that the metal core thereof is melted, chemically converted as applicable and/or destroyed, at least in part.

Abrégé
The invention relates to a method for modifying the surface of powdery particles by means of silane compounds. According to the invention, in order to perform the method economically, said method comprises the steps of introducing the powdery particles into a reaction mixture comprising a silane component and a liquid alcoholic component, wherein the liquid alcoholic component comprises an alcoholic reactive component, and then chemically reacting the silane component and the alcoholic reactive component in the presence of the particles, wherein reaction products formed during the reaction are deposited on the surface of the particles, a primary particle preparation thus being formed.
