Patent number: 5599648Abstract: Surface reforming of a polymeric article containing a polymerizable compound is effectively performed by polymerizing the polymeric article in contact with a surface reforming medium because the transfer of the material constituting the surface reforming medium to the polymeric article is enhanced by the polymerization. The surface reforming can be performed locally selectively, i.e., imagewise. The remaining un-polymerized part may be subjected to further surface reforming, e.g., by using another type of surface reforming medium or attachment of powder, to provide an enhanced contrast of surface property. Such an enhanced contrast of surface property can be effectively used, e.g., for production of a printing plate.Type: GrantFiled: November 26, 1993Date of Patent: February 4, 1997Assignee: Canon Kabushiki KaishaInventors: Yuji Kondo, Masato Katayama, Akihiro Mouri

Patent number: 5533452Abstract: A printing method for an in situ plate production process in which a photosensitive plate blank having a polymerization layer between a support and a release film is fixed to a plate cylinder either before or after forming a polymerization-nonpolymerization pattern in the polymerization layer. The polymerization layer can be a thermal development-type photosensitive layer for forming the pattern. The release film is then peeled apart from the plate blank to leave a printing plate on the plate cylinder, which can be used for printing and for an inking step. The printing pattern of the plate can be formed by selective removal of the unpolymerized part or by selective transfer of the release film to the polymerized part of the polymerization layer.Type: GrantFiled: November 4, 1994Date of Patent: July 9, 1996Assignee: Canon Kabushiki KaishaInventors: Akihiro Mouri, Tsuyoshi Shibata, Yuji Kondo
