Title:
COLORED FINE PARTICLES, THEIR PRODUCTION AND ELECTROPHOTOGRAPHIC TONER
Document Type and Number:
Japanese Patent JP3188842
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To obtain colored fine particles excellent in dispersibility and stability of a charged state through simplified producing processes.
SOLUTION: When a polymerizable monomer compsn. prepd. by dispersing a colorant in at least a polymerizable monomer is suspended in an aq. dispersive medium and polymerized to obtain colored fine particles, the colorant is dispersed in the polymerizable monomer in the presence of a dispersant, the viscosity of the polymerizable monomer compsn. is regulated to ≤300cP and the viscosity of the compsn. after suspension in the aq. dispersive medium is regulated to ≤100cP.
