Patent number: 8420730Abstract: The present disclosure provides a capsulated colorant including a colorant and a polymer resin coating the colorant, wherein the polymer resin is obtained by polymerization of a polymerizable composition including a basic monomer, a macromonomer and a polymerizable unsaturated monomer; a method of preparing the capsulated colorant; and an ink composition including the capsulated colorant.Type: GrantFiled: March 2, 2010Date of Patent: April 16, 2013Assignee: Samsung Electronics Co., Ltd.Inventors: Jong-In Lee, Sang-Eum Shim -
Patent number: 8404084Abstract: A filler treatment process enhances the fixation of anionic latex on filler in a short time. Anionic polymer dispersions (latex) are added to papermaking filler slurries at ambient temperature and then mixed with water of temperature higher than the glass transition temperature (Tg) of the latex used. The anionic latexes applied by this process are totally and irreversibly fixed or bound onto the filler particles and the treated filler particle agglomerate to form an aggregated filler slurry which is stable over time. The latex-treated filler slurry can be added to papermaking furnishes at any point prior to the headbox of the paper machine or stored for later use. The latex-treated filler slurry improves filler retention, only slightly reduces sheet strength and improves sizing performance.Type: GrantFiled: August 30, 2011Date of Patent: March 26, 2013Assignee: FPInnovationsInventors: Makhlouf Laleg, Roderick Collins, Danielle Gagne, Steven Middleton

Publication number: 20130066011Abstract: A method of preparing a low odour polymer latex composition comprises polymerising a monovinylidene monomer such as styrene and a conjugated diene such as butadiene in the presence of a linear alkyl thiol chain transfer agent. The resulting polymer latex is treated with an oxidising agent to oxidise residual chain transfer agent to volatile decomposition products that are then removed by steam stripping.Type: ApplicationFiled: December 16, 2010Publication date: March 14, 2013Inventors: Bernard Fouchet, Gerold Lohmüeller, Patric Eckerle
