    • A composite particle that can be easily converted to cured particle or half cured particle by the use of carbodiimide resin without changing of the configuration of matrix particle of, for example, a thermoplastic resin, excelling in mechanical and functional characteristics by virtue of the reaction capability inherently possessed by a carbodiimide group. In particular, a composite particle comprising matrix particle (A) having a functional group capable of reacting with a carbodiimide group and carbodiimide resin (B), characterized in that the functional group of the matrix particle (A) couples with the carbodiimide group of the carbodiimide resin (B) and that the composite particle is provided with an outer shell layer of carbodiimide resin (B) having an average thickness diameter (L), defined by the following formula [1], ranging from 0.01 to 20 mum: L = (L2 - L1)/2 [1] wherein L1 represents the average diameter of matrix particle, and L2 represents the average diameter of composite particle.
    • 通过使用碳化二亚胺树脂,可以容易地转变为固化颗粒或半固化颗粒而不改变例如热塑性树脂的基质颗粒的构型,由于反应能力而具有优异的机械和功能特性的复合颗粒 固有地由碳二亚胺基团拥有。 特别是,含有具有能够与碳二亚胺基反应的官能团的基质颗粒(A)和碳化二亚胺树脂(B)的复合颗粒,其特征在于,基质颗粒(A)的官能团与碳化二亚胺 碳二亚胺树脂(B),并且该复合颗粒具有由下式[1]定义的平均厚度直径(L)的碳二亚胺树脂(B)的外壳层,其厚度范围为0.01至20μm:L = (L2-L1)/ 2 [1]其中L1代表基质颗粒的平均直径,L2代表复合颗粒的平均直径。
