PRODUCTION OF POLYMERIC PARTICLES AND ROUGH COATINGS BY INK JET PRINTING

A method for producing polymer particles is disclosed in which a fluid preparation is ejected in drop form from a nozzle of an ink jet print head. At least one nozzle ejects droplets in response to electrical signals, and radiation from a radiation source is directed on the droplets in flight, where...

Zusammenfassung:A method for producing polymer particles is disclosed in which a fluid preparation is ejected in drop form from a nozzle of an ink jet print head. At least one nozzle ejects droplets in response to electrical signals, and radiation from a radiation source is directed on the droplets in flight, whereby the fluid preparation is at least partially cured by irradiation, so that particles are obtained from the fluid drops before impact or collection. The fluid preparation contains a prepolymer, an oligomer, monomers, or reactive diluents as well as at least one photoinitiator. The fluid preparation has a polymerizable group that is radically polymerizable. Further, a printed product and a device for making the printed product are disclosed. The printed product has a rough polymeric coating that is composed of spherical or largely spherically shaped polymer particles.
