Abstract
The present invention is directed to an embossing tool having a microstructure on its surface wherein the surface of the embossing tool has a thin layer of gold or an alloy thereof. Such an embossing tool not only can reduce adhesion between the surface of the embossing tool and a cured material, but also does not cause any significant change to the profile of the microstructure.
