Publication number: 20140024763Abstract: The invention provides a process for producing a pigment-encapsulating polymer dispersion, comprising the steps of dispersing a liquid containing a monomer, a hydrophobe and a polymerization initiator into a water medium with a dispersant to obtain a monomer emulsion, and mixing the monomer emulsion with a pigment dispersion containing a self-dispersible pigment to which a hydrophilic group is bonded directly or through another atomic group and which is dispersed by the hydrophilic group, subjecting the resultant mixture to a shearing treatment and then polymerizing the monomer.Type: ApplicationFiled: June 27, 2013Publication date: January 23, 2014Inventors: Masanori Jinnou, Takahiro Mori, Satoru Kobayashi, Shinichi Sakurada, Yutaka Kurabayashi

Publication number: 20130251895Abstract: An image recording method includes recording an intermediate image by applying an ink to an intermediate transfer body and transferring the intermediate image onto a recording medium while heating the intermediate image. The ink contains a coloring material and polymer fine particles which are a mixture of a crystalline polymer and an amorphous polymer. In transferring the intermediate image, the intermediate image is heated to a temperature equal to or higher than a melting point of the crystalline polymer and equal to or higher than a glass transition point of the amorphous polymer.Type: ApplicationFiled: March 13, 2013Publication date: September 26, 2013Applicant: CANON KABUSHIKI KAISHAInventors: Masanori Jinnou, Naofumi Shimomura, Satoru Kobayashi

Publication number: 20130251416Abstract: An image recording method includes recording an intermediate image by applying an ink to an intermediate transfer body, and transferring the intermediate image onto a recording medium while heating the intermediate image. The ink contains a coloring material and polymer fine particles which have an interpenetrating polymer network structure constituted by a crystalline polymer and an amorphous polymer. In transferring the intermediate image, the intermediate image is heated to a temperature equal to or higher than a melting point of the crystalline polymer and equal to or higher than a glass transition point of the amorphous polymer.Type: ApplicationFiled: March 13, 2013Publication date: September 26, 2013Applicant: CANON KABUSHIKI KAISHAInventors: Akiko Tominaga, Masanori Jinnou
