The electron donors are arylsulfinate salts having a cation that contains at least one carbon atom and either a positively charged nitrogen atom or a positively charged phosphorus atom. Methods of polymerization are also provided that can be used to prepare polymeric material with the initiator systems. The initiator systems can be thermal initiator systems, photoinitiator systems, or combinations thereof.Type: GrantFiled: September 26, 2003Date of Patent: April 18, 2006Assignee: 3M Innovative Properties CompanyInventors: Rajdeep S. Kalgutkar, Michael C. Palazzotto

Patent number: 6984262Abstract: Described is a coating composition adapted to enhance the adhesion of a polymeric coating or film applied to a substrate. The coating composition is interposed between the substrate and the polymeric coating and comprises (a) at least one coupling agent, partial hydrolysates thereof or mixtures thereof in a concentration greater than 25 weight percent, based on the weight of the total composition, and (b) an adhesion enhancing amount of an epoxy-containing material having at least two epoxy groups. The coating composition is substantially free of photochromic materials and colloidal particles chosen from silica, alumina or mixtures thereof. Also described is a process for using the coating composition and articles coated with the composition and additional coatings and films which can be photochromic.Type: GrantFiled: July 16, 2003Date of Patent: January 10, 2006Assignee: Transitions Optical, Inc.Inventors: Eric M. King, James P. Colton, Jessica A. Hoch
