Document Type and Number:
Japanese Patent JP6877685
Kind Code:
B2
Abstract:
The invention relates to a composite aggregate resin particle group, a method for preparing the particle group, and composition containing the particle group. Composite aggregate resin particles are useful for an additive having a certain extinction effect on coatings and resin forming products in an observation view. White points exist in a surface or foreign body sensation exists during touch, and then subjects exist in the quality of the coatings and the resin forming products. The invention provides a composite aggregate resin particle group which can maintain excellent extinction effect acquired by composite aggregate resin particles and can improve the quality of the resin forming products and the coatings. Raw material aggregate resin particles formed by micro resin particles and ethylene polymer are composited into amorphous composite aggregate resin particles which form the particle group. The volume mean grain size of the composite aggregate resin particles is 2-150 [mu]m, and spherical particles in particles having grain size greater than the volume mean grain size accounts for less than 0.3%.
