Abstract:
1. A method of using a stable viscosity coating composition, comprising: forming a transfer layer on a substrate from transfer layer material; coating the transfer layer with the stable viscosity coating composition to form a coating, the stable viscosity coating composition comprising at least one vinyl ether, a stabilizer and a photoacid generator; contacting the coating with a template having a relief pattern that includes recesses therein so that the coating essentially completely fills the recesses in the relief pattern in the template to transfer the relief pattern to the coating; exposing the coating to radiation through the template; forming a relief image in the coating by releasing the coating from the template, said releasing resulting in voids in the coating, wherein the relief image is a solidified reverse image replica of the relief pattern in the template; wherein: the at least one vinyl ether includes at least one vinyl ether group (CR2═CRO—), and wherein the at least one vinyl ether is represented by the structure: C(R wherein the stabilizer includes at least one of structures: wherein F comprises either a carbon or a silicon atom, S is sulfur and N is nitrogen; wherein q and r independently represent an integer from 0 to 6; wherein a sum of the integers q and r is ≦6; wherein each R wherein the alkyl substituents in the tris-trialkylsilyl group include linear, branched, cyclic or bicyclic alkyl substituents having 1 to 21 carbon atoms; wherein the aryl substituents in the tris-triarylsilyl group include phenyl, naphthyl or phenanthryl; wherein the alkaryl substituents in the tris-trialkarylsilyl group include tolyl; wherein the aralkyl substituents in the tris-triaralkylsilyl group include benzyl; wherein the alkenyl substituents in the tris-trialkenylsilyl group include vinyl; wherein the fluoroalkyl substituents in the tris-trifluoroalkyl group include linear or branched fluorinated alkyl groups having 2-12 carbon atoms, or fluorinated cycloalkyl groups having 3-17 carbon atoms; wherein the alkynl substituents in the tris-trialkynylsilyl group include ethynyl groups; and wherein any two of R
