Embossed micro-structure with cured transfer material method

摘要

A method of making an embossed micro-structure includes providing a transfer substrate, an emboss substrate, and an embossing stamp having one or more stamp structures. Transfer material is coated on the transfer substrate. The transfer material on the transfer substrate is contacted with the stamp structures to adhere transfer material to the stamp structures. A curable emboss layer is coated on the emboss substrate. The stamp structures and adhered transfer material are contacted to the curable emboss layer on the emboss substrate to emboss a micro-structure in the curable emboss layer and transfer the transfer material to the embossed micro-structure. The curable emboss layer is cured to form a cured emboss layer having embossed micro-structures corresponding to the stamp structures and having transfer material in the embossed micro-structures. The stamp structures is removed from the cured emboss layer, substantially leaving the transfer material in the micro-structure.
