Popis:	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.
