Abstract
Official abstract text for this publication.
A resin particle composition includes resin particles, polishing agent particles having an average circle-equivalent diameter of 0.1 μm to 3.0 μm, and silica particles having a compression aggregation degree of 60% to 95% and a particle compression ratio of 0.20 to 0.40.
First claim
Opening claim text (preview).
What is claimed is: 1. A resin particle composition, comprising: resin particles; polishing agent particles having an average circle-equivalent diameter of 0.1 μm to 3.0 μm; and silica particles having a compression aggregation degree of 60% to 95% and a particle compression ratio of 0.20 to 0.40; wherein the silica particles are surface-treated with a siloxane compound having a viscosity of 1,000 cSt to 50,000 cSt, and the surface attachment amount of the siloxane compound is from 0.01% by weight to 5% by weight. 2. The resin particle composition according to claim 1 , wherein an average circle-equivalent diameter of the silica particles is from 40 nm to 200 nm. 3. The resin particle composition according to claim 1 , wherein a particle dispersion degree of the silica particles is 90% to 100%. 4. The resin composition according to claim 1 , wherein the siloxane compound is silicone oil. 5. The resin particle composition according to claim 1 , wherein an average circularity degree of the silica particles is 0.85 to 0.98. 6. The resin particle composition according to claim 1 , wherein the silica particles are sol-gel silica particles. 7. The resin particle composition according to claim 1 , wherein a ratio (Da/Dsi) of the average circle-equivalent diameter (Da) of the polishing agent particles to the average circle-equivalent diameter (Dsi) of the silica particles is from 0.5 to 75.
