Method for producing a defined three-dimensional relief-type structure on a surface of a provided medium

摘要

The method for the production of defined three-dimensional relief-like structure (1, 2) on a surface of a carrier (3) to be allocated useful as embossed printing, comprises allocating two reaction components (10, 13) with a pH value of less than 7. The reaction components react in reactive contact area with one another and produce the desired structure on the carrier. The first reaction component is allocated in the form of a polyisocynate on the basis of toluylene diisocyanate and the second reaction component is allocated in the form of alcohol containing fluid dye carrier or ink. The method for the production of defined three-dimensional relief-like structure (1, 2) on a surface of a carrier (3) to be allocated useful as embossed printing, comprises allocating two reaction components (10, 13) with a pH value of less than 7. The reaction components react in reactive contact area with one another and produce the desired structure on the carrier. The first reaction component is allocated in the form of a polyisocynate on the basis of toluylene diisocyanate and the second reaction component is allocated in the form of alcohol containing fluid dye carrier or ink. The reaction components comprise a portion of carboxylic acid. A local hardening or local foaming is carried out during the reaction of the components. The quantity portion of the second reactive component is 1% compared to the total quantity of both reaction components. The second reaction component is subjected two-dimensionally with the contour of the desired structure defined with the first reaction component. The components overlap itself for triggering of the reaction in a pattern (16), which corresponds to the desired structure. The reaction components are sputtered as fluid droplets (14, 15) on the carrier. An independent claim is included for a three-dimensional relief-like structure.
