    Abstract: PROBLEM TO BE SOLVED: To provide a colorant for toner which has high concealing property, excellent color developing property and coloring property, and constant charging property, and to provide a toner and a developer containing the colorant for toner. SOLUTION: The colorant for toner is made of composite particles, which comprise pigment particles dispersed in a polymer phase containing a structural unit derived from polymerizable crosslinking monomers and a structural unit derived from water-soluble monomers and which have at least one vacancy in the particle. The toner contains at least a binder resin and the colorant for toner. The developer contains the toner and a carrier. COPYRIGHT: (C)2010,JPO&INPIT

    Abstract: PROBLEM TO BE SOLVED: To provide a copolymer latex excellent in printing aptitude, etc., and especially, even if the printing velocity range is over a wide range, forming coated paper excellent in the printing aptitude. SOLUTION: This copolymer latex is provided by containing (B) a copolymer obtained by the emulsion polymerization of a second monomer component consisting of prescribed amounts of (d) an aliphatic conjugated diene-based monomer, (e) a vinyl cyanide monomer, (f) an ethylenically unsaturated carboxylic acid monomer and (g) another monomer copolymerizable with the (d) through (f) [provided that, (d)+(e)+(f)+(g)=100 mass%] in the presence of a polymer (A) obtained by emulsion-polymerizing prescribed amounts of (a) an aliphatic group diene-based monomer, (b) an ethylenically unsaturated carboxylic acid monomer and (c) another monomer copolymerizable with the (a) and (b) [provided that (a)+(b)+(c)=100 mass%], and having 50 to 120 nm number-average particle diameter of the copolymer (B).
