Title:
微小空洞中に封入された添加剤を具有するポリマー粒子
Document Type and Number:
Japanese Patent JP2011529203
Kind Code:
A
Abstract:
Porous particles comprising a polymer binder and at least one additive distinct from any pore stabilizing compound present in the particle, wherein: the polymer binder comprises a solid compositionally continuous phase having an external particle surface; discrete pores are dispersed within the solid compositionally continuous phase, forming internal pore surfaces; and the at least one additive is present primarily in the discrete pores. The additive may further preferably not be present in the solid compositionally continuous phase, and be substantially absent from the external particle surface. A toner set for forming a color electrophotographic image comprising a plurality of different colored toners, where at least one of the different colored toners comprise such porous particles comprising additives, and in a particular embodiment wherein at least two different colored toners each comprise different pigments present primarily in the internal pores. A process of making such porous particles.
