Method for producing a multi-layer body, and multi-layer body
First Claim
1. A process for the production of a multi-layer body having at least one partially shaped functional layer in register relationship with at least one further partially shaped layer, wherein a first layer in the form of a first photoresist lacquer layer is formed on a carrier layer and partially exposed, the exposed first layer is developed and structured and then using the structured first layer as a mask layer the at least one partially shaped functional layer and/or the at least one further partially shaped layer is formed.

Abstract
Described are various processes for the production of multi-layer bodies having at least one partially shaped functional layer and at least one further partially shaped layer and the multi-layer bodies produced in that way. The multi-layer body has at least one partially shaped functional layer in register relationship with at least one further partially shaped layer, which preferably supplement each other to provide a geometric, alphanumeric, pictorial, graphic or figurative colored representation.

- 31. A multi-layer body comprising at least one partially shaped functional layer in register relationship with at least one further partially shaped layer, wherein a first layer in the form of a first photoresist lacquer layer is produced structured in pattern form on a carrier layer and using the structured first layer as a mask layer the at least one partially shaped functional layer and/or the at least one further partially shaped layer is formed.

54. A process for the production of a multi-layer body having at least one partially shaped functional layer in register relationship with at least one further partially shaped layer, the process comprising the steps of:
-
providing a first photoresist lacquer layer on a carrier layer; partially exposing the first photoresist lacquer layer with radiation to form exposed regions of the first photoresist lacquer layer and unexposed regions of the first photoresist lacquer layer; removing one of the exposed regions or the unexposed regions of the first photoresist lacquer layer from the carrier layer to form a structured first photoresist lacquer layer; providing a second photoresist lacquer layer on the carrier layer; using the structured first photoresist lacquer layer as a mask layer to partially expose the second photoresist lacquer layer with radiation to form exposed regions of the second photoresist lacquer layer and unexposed regions of the second photoresist lacquer layer; and removing one of the exposed regions or the unexposed regions of the second photoresist lacquer layer from the carrier layer to form a structured second photoresist lacquer layer in register relationship with the structured first photoresist lacquer layer.
