Ultra-fine particle design
technologies, with emulsion polymerization and suspension
polymerization for micron- and sub-micron-level polymers,
play vital roles in the polymerized toner and latex businesses.
ZEON plans to further develop this technology through
the Information Materials Laboratory I and the Latex Laboratory.
Information Materials Laboratory I
ZEON developed the world's first polymerized toner.
In contrast to conventional kneading and pulverizing methods,
polymerized toner is directly manufactured through mixing
colorant carbon into raw material monomer, and then polymerizing
and drying the material to produce uniform ultra-fine
particles of less than 10 microns.
Although polymerized toner was previously
regarded as a dream toner due to its excellent properties,
manufacturing was delayed due to the technical difficulties
of development. However, ZEON's accumulated expertise
in polymerization technology enabled the company to develop
the world's first polymerized toner on a commercial basis.
Since then, the kinds of laser and LED printers using
Zeon's polymerized toner has steadily increased, with
the company receiving high marks for the toner's high-quality
printing.
