AI Technical Summary
Technical Problem
Existing toner compositions face challenges in meeting environmental regulations due to the use of titanium dioxide, which requires labeling, and suffer from ghosting and reduced image density due to inadequate triboelectric charge management.
Method used
A core-shell structured external additive for toners, comprising tin oxide as the core and a shell coated with a silane-based compound and aluminum hydroxide, addresses these issues by providing an alternative to titanium dioxide and managing triboelectric charge.
Benefits of technology
The solution enhances environmental compliance, reduces ghosting, and increases image density, thereby improving print quality and durability.
