摘    要:利用分光光度计对国内外铜金粉的颜色进行了测试, 研究了铜金粉的成分、 微观状态对颜色的影响。 结果表明: 铜金粉颜色可以用色彩三要素进行描述,其中铜金粉的色相只与合金成分有关, 而与铜金粉片的大小、 形状及粒度分布无关; 明度和纯度与铜金粉片在油墨层中定向排列状态、 片的大小、 形状及粒度分布有关,而与成分无关; 合金成分的微小波动不会引起铜金粉色相的明显改变。

Abstract: Spectrophotometer was used to measure the color of the bronze powders made in home and abroad, and some factors that have influence on color were analyzed. The results show that the three factors in color are suitable to the colorful description about bronze powder. The pigment’s hue is more relative to the composition of alloy than the particle diameter, shape, and size distribution; however, the particles’ morphologies and location have great influence on the brightness and chromatic value. Besides, it is found that the metallic pigment’s hue is insensitive to the variation of the composition of alloy.
