Title: LOW VISCOSITY MONOMER FOR PATTERNING OPTICAL TAPE
Abstract:
A method for forming an optical tape for data storage from a substrate film includes a step of patterning a curable liquid composition onto a side of the substrate film. Characteristically, the curable liquid composition includes a free radical photoinitiator and a polymerizable component that includes at least one acrylate. The curable liquid composition is illuminated with actinic radiation to form a patterned imprint layer disposed over the substrate film. A multilayer data recording assembly is placed over the imprint layer. An optical tape made by the method is also provided.
