摘 要: 利用分光光度計(jì)對(duì)國內(nèi)外銅金粉的顏色進(jìn)行了測(cè)試， 研究了銅金粉的成分、 微觀狀態(tài)對(duì)顏色的影響。 結(jié)果表明： 銅金粉顏色可以用色彩三要素進(jìn)行描述，其中銅金粉的色相只與合金成分有關(guān)， 而與銅金粉片的大小、 形狀及粒度分布無關(guān)； 明度和純度與銅金粉片在油墨層中定向排列狀態(tài)、 片的大小、 形狀及粒度分布有關(guān)，而與成分無關(guān)； 合金成分的微小波動(dòng)不會(huì)引起銅金粉色相的明顯改變。
關(guān)鍵字: 銅金粉； 顏色； 色相； 明度； 純度

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.
Key words: bronze powder; color; hue; brightness; chromatic value
