摘要： A polymeric monomer (A) having as a main component thereof a (meth)acryl type monomer which is subjected to aqueous suspension polymerization in the presence of a compound (B) which is substantially insoluble in water and sparingly soluble in the polymeric monomer (A). The compound (B) has at least one, preferably two or more, structural units, selected from the group consisting of --SH, --S--S--, --COOH, --NO.sub.2, and --OH. The use of compound (B), in the suspension polymerization of the (meth)acryl type monomer, represses of the production of by-produced minute particles due to sympathetic emulsion polymerization. The suspension polymerization permits production of (meth)acryl type polymer particles having high heat stability and a small range of particle diameters.

摘要： Colored microfine globular particles are produced by causing carbon black to react with a polymer capable of reacting with the carbon black thereby forming a carbon black-graft polymer, dispersing this carbon black-graft polymer in a polymerizable monomer component, and then polymerizing the polymerizable monomer component. These particles, in the unmodified form, are usable as a toner for the development of images of static charge and, in a form incorporated in a varying component, are usable such as in resin composition, coating composition, thermosensitive transfer ink ribbon coating agent, thermosensitive transfer ink, or back-coating agent for magnetic recording medium.
