Title:
CORE-SHELL TYPE PARTICLE AND TOWER
Document Type and Number:
Japanese Patent JP2023176415
Kind Code:
A
Abstract:
To provide core-shell type particles that are highly effective as a mold release agent because the mold release agent can ooze out even with lighter pressure during fixing.SOLUTION: Core-shell type particles have a core and a shell on the surface of the core. The core contains a crystalline mold release agent. A sum of the number average value and standard deviation of a Feret diameter of the particles is 20 to 500 nm. The shell comprises an organosilicon polymer. In differential scanning calorimetry of the particles, a maximum endothermic peak exists when a temperature is raised from 30°C to 120°C at a rate of 10.0°C/min, a maximum exothermic peak exists when the temperature is lowered from 120°C to 30°C at a rate of 10.0°C/min, and when a peak temperature of the maximum endothermic peak is Tm (°C) and a peak temperature of the maximum exothermic peak is Tc (°C), the Tc is lower than the Tm by 5°C or more.SELECTED DRAWING: None
