摘要

本研究使用了十四种来自商业来源的还原染料。它们的耐光性采用(a)蓝色等级，(b) CIE系统和(c) Hunter L,a,b等级进行测量。从所得结果来看，Hunter L,a,b标度比CIE标度更容易评价耐光性;对于单个颜色，首选ΔA和ΔE来测量耐光性，对于不同的颜色，首选ΔL和ΔC。

Colour difference analysis of lightfastness for some vat dyes

Fourteen vat dyes from a commercial source were used in this investigation. Their lightfastness was measured by (a) the Blue Scale, (b) the CIE system, and (c) the Hunter L,a,b scale.

From the results obtained, it was found that the Hunter L,a,b scale was easier for evaluating the lightfastness than the CIE system; for individual colours ΔA and ΔE were preferred for measuring the lightfastness, and for different colours ΔL and ΔC were preferred.
