COLORED PARTICULATE BLENDS AND METHODS FOR PRODUCTION AND USE THEREOF

To provide colored powder particulates for forming printed materials with coloring in additive manufacturing.SOLUTION: Colored particulate blends may be produced by combining thermoplastic polymer particulates that differ from one another in color. Such colored particulate blends may comprise: a first plurality of thermoplastic polymer particulates comprising a first thermoplastic polymer and a first colorant blended with the first thermoplastic polymer in an interior of the thermoplastic polymer particulates, and a second plurality of thermoplastic polymer particulates comprising a second thermoplastic polymer and, optionally, a second colorant blended with the second thermoplastic polymer in an interior of the thermoplastic polymer particulates. The first plurality of thermoplastic polymer particulates have a first color, and the second plurality of thermoplastic polymer particulates have a second color different than the first color, and the second colorant, if present, is different from the first colorant. The colored particulate blends are visually homogenous and appear as a single color different from the first color and the second color.SELECTED DRAWING: Figure 1 【課題】付加製造において、着色を有する印刷物を形成するための着色粉末粒子を提供する。【解決手段】着色粒子ブレンドは、色が互いに異なる熱可塑性ポリマー粒子を組み合わせることによって製造することができ、第１の熱可塑性ポリマーと、熱可塑性ポリマー粒子の内部で第１の熱可塑性ポリマーとブレンドされた第１の着色剤とを含む第１の複数の熱可塑性ポリマー粒子と、第２の熱可塑性ポリマーと、任意選択的に、熱可塑性ポリマー粒子の内部で第２の熱可塑性ポリマーとブレンドされた第２の着色剤とを含む第２の複数の熱可塑性ポリマー粒子とを含んでもよい。第１の複数の熱可塑性ポリマー粒子は第１の色を有し、第２の複数の熱可塑性ポリマー粒子は第１の色とは異なる第２の色を有し、第２の着色剤は、存在する場合、第１の着色剤とは異なる。着色粒子ブレンドは視覚的に均質であり、第１の色及び第２の色とは異なる単一の色として見える。【選択図】図１
