摘要:
The invention relates to a process for the preparation of a polymeric relief structure comprising the steps of coating a substrate with a coating composition comprising one or more radiation-sensitive ingredients, locally treating the coated substrate with electromagnetic radiation having a periodic or random radiation-intensity pattern, forming a latent image, and polymerizing and/or crosslinking the resulting coated substrate, wherein the coating composition comprises one or more RAFT agents.

摘要:
Disclosed is a method for generating conductive surface patterns on a substrate by coating the substrate with a predetermined pattern of electrically conductive particles or of particles of a material that can be converted by heating into an electrically conducting material, and sintering or melting the coated substrate by means of electromagnetic radiation and by applying an antenna for said electromagnetic radiation in the vicinity of the predetermined pattern.The process is easy to implement, needs only low energy, is very fast and can be used to generate electrically conductive patterns at low cost.
