Title (EN) METHOD FOR MANUFACTURING CORE-SHELL STRUCTURE FINE PARTICLES AND TONER
(FR) PROCÉDÉ DE PRODUCTION DE FINES PARTICULES À STRUCTURE CŒUR-COQUILLE ET TONER
Abstract: front page image
(EN)The method for manufacturing core-shell structure fine particles, includes adding metal salt into an aqueous medium containing shell particles A and core particles B to thereby attach the shell particles A to the surface of each of the core particles B and the toner contains the core-shell structure fine particles. (1) The zeta potential of the core particles B and the zeta potential of the shell particles A are the same polarity. (2) |Zeta potential of the core particles B when adding metal salt|< |Zeta potential of the shell particles A when adding metal salt| (3) (Median diameter based on the volume of the core particles B)>(Median diameter based on the volume of the shell particles A).
(FR)Cette invention concerne un procédé de production de fines particules à structure cœur-coquille, ledit procédé comprenant l'ajout d'un sel métallique dans un milieu aqueux contenant des particules de coquille A et des particules de cœur B pour fixer ainsi les particules de coquille A à la surface de chacune des particules de cœur B ; et un toner contenant lesdites fines particules à structure cœur-coquille. (1) Le potentiel zêta des particules de cœur B et le potentiel zêta des particules de coquille A ont la même polarité. (2) |Potentiel zêta des particules de cœur B lors de l'ajout du sel métallique|< |Potentiel zêta des particules de coquille A lors de l'ajout du sel métallique| (3) (Diamètre médian basé sur le volume des particules de cœur B)>(Diamètre médian basé sur le volume des particules de coquille A).
