CORE-SHELL PARTICLE, AND TONER - A simplified explanation of the abstract

This abstract first appeared for US patent application 18324840 titled 'CORE-SHELL PARTICLE, AND TONER

Simplified Explanation

The patent application describes a core-shell particle with a crystalline release agent in the core and an organosilicon polymer shell. The particle has a specific size range and exhibits specific thermal properties.

• Core-shell particle with a core and a shell
• Core contains a crystalline release agent
• Particle size is between 20 and 500 nm
• Shell is made of an organosilicon polymer
• Differential scanning calorimetric measurement shows specific thermal behavior
• Maximum endothermic peak at temperature increase from 30°C to 120°C
• Maximum exothermic peak at temperature decrease from 120°C to 30°C
• Tc (peak temperature of exothermic peak) is at least 5°C lower than Tm (peak temperature of endothermic peak)

Original Abstract Submitted

A core-shell particle includes a core, and a shell on a surface of the core. The core includes a crystalline release agent. A value of a sum of a number-average value of Feret diameter of the core-shell particle and a standard deviation of the Feret diameter of the core-shell particle is 20 to 500 nm. The shell comprises an organosilicon polymer. In a differential scanning calorimetric measurement of the core-shell particle, a maximum endothermic peak is present when a temperature is raised from 30° C. to 120° C. at 10.0° C./min, a maximum exothermic peak is present when the temperature is lowered from 120° C. to 30° C. at 10.0° C./min, and Tc (° C.) is at least 5° C. lower than Tm (° C.) where Tm is a peak temperature of the maximum endothermic peak and Tc is a peak temperature of the maximum exothermic peak.
