摘要： A powder coating is provided, comprising a particulate material having a particle distribution satisfying the following requirements:(a) the volume 50% diameter is from 7 .mu.m to 20 .mu.m;(b) the proportion by volume of particles having a particle diameter of not less than 30 .mu.m is not more than 20%; and(c) the proportion by population of particles having a particle diameter of not more than 5 .mu.m in the particulate material is not more than 65%, the particulate material also has an external additive attached to the surface thereof, the percent coverage by the external additive (determined by an equation described in the specification) being from 30 to 200%. The powder coating can provide a film having a reduced thickness with an improved leveling, thus improving working efficiency. In addition, the fractions of the powder coating from the coating process can be recycled and re-used, thereby reducing the total cost.
摘要翻译：提供粉末涂料，其包含具有满足以下要求的颗粒分布的颗粒材料：（a）体积50％直径为7μm至20μm; （b）粒径不小于30μm的粒子的体积比不大于20％; 和（c）颗粒材料中粒径不超过5μm的粒子的比例不超过65％，颗粒材料也具有附着在其表面上的外部添加剂，百分比覆盖率外部添加剂（由说明书中描述的等式确定）为30至200％。粉末涂料可以提供具有减小的厚度的膜，并且改善流平性，从而提高工作效率。此外，涂层工艺中的粉末涂层的分数可以再循环使用，从而降低总成本。

摘要： A powder coating is provided, comprising a particulate material having a particle diameter satisfying the following requirements:(a) the volume 50% diameter be from 7 to 15 .mu.m;(b) the proportion by volume of the particles having a particle diameter of not less than 20 .mu.m and those having a particle diameter of not less than 30 .mu.m in the particulate material be not more than 10% and 0%, respectively; and(c) the proportion by population of the particles having a particle diameter of not more than 5 .mu.m in the particulate material be not more than 50%, the particulate material having an external additive attached to the surface thereof, the percent coverage by the external additive determined by the following equation described in the specification being from 30 to 100%. The powder coating can provide a film having a reduced thickness with an improved leveling and hence make it possible to improve the working efficiency and re-use the fractions of the powder coating recycled from the coating process, realizing the reduction of the total cost.

摘要： A pressure-fixable toner is produced by: dispersing or dissolving a mixture containing (a) a colorant and/or magnetic particles, (b) a pressure fixable binding material, and (c) a capsule wall-forming resin, in an organic solvent; dispersing the resulting dispersion or solution in a dispersion-stabilizing solution; heating the dispersion to evaporate off the solvent; dispersing the resulting encapsulated toner in a lower alcohol to remove the solvent remaining within the encapsulated toner; and thereafter drying the toner. The toner can be used to develop images in electrophotographic systems.
