METHOD FOR PRODUCING UNIFORM POLYMETHYLMETHACRYLATE LAYERS

摘要

A method for producing smooth uniform polymethylmethacrylate (PMMA) layers having a thickness of greater than 20 mu m. The PMMA layers are produced utilizing a solution of polymethylmethacrylate in an ester of lactic acid. The PMMA layers are particularly suited for micro-structuring techniques which utilize high-energy, ionizing radiation. The PMMA layers exhibit a good adhesion to metallic, semi-conducting and insulating substrates.
