A stable viscosity coating composition, a method of forming the stable viscosity coating composition and a method for using the stable viscosity coating composition in a micro-molding imprint lithographic process, such as Step and Flash Imprint Lithography is disclosed. The stable viscosity coating composition may include at least one vinyl ether having at least one vinyl ether group (—OCR═CR), and a stabilizer, wherein the stabilizer may be 9-anthracenemethanol, a substituted 9-anthracenemethanol, phenothiazine, or a substituted phenothiazine. The coating composition may include a radiation sensitive photoacid generator (PAG). The method of forming the coating composition comprises combining at least one vinyl ether having at least one vinyl ether group (—OCR═CR), and at least one stabilizer. 2. The stable viscosity coating composition of claim 1 , wherein the at least one vinyl ether has the structure:{'br': None, 'sup': 1', '2', '3', '4', '5', '6', '7', '8, 'sub': 'n', 'C(R)(R)═C(R)OC(R)(R)(D)(R)(R)(R)\u2003\u2003(I);'}wherein D is a carbon atom or a silicon atom;wherein n is an integer from 0 to 6; and{'sup': 1', '2', '3', '4', '5', '6', '7', '8, 'wherein R, R, R, R, R, R, R, Rare independently a hydrogen atom, a fluorine atom or a hydrocarbyl substituent with a primary, a secondary or a tertiary carbon attachment point.'}3. The stable viscosity coating composition of claim 1 , wherein the at least one vinyl ether has the structure:{'br': None, 'sup': 9', '10', '11', '12', '13', '14', '15', '16', '17', '18, 'sub': o', 'p, 'C(R)(R)═C(R)OC(R)(R)C(R)(R)(R)(R)(R)\u2003\u2003(II);'}wherein E is a carbon atom or a silicon atom;wherein o and p are independently integers from 0 to 6 and a sum of o and p is less than or equal to 6; and{'sup': 9', '10', '11', '12', '13', '14', '15', '16', '17', '18, 'wherein R, R, R, R, R, R, R, R, Rand Rare independently a hydrogen atom, a fluorine atom or a hydrocarbyl substituent with a primary, a secondary or a tertiary carbon ...
