The core application of C.I. Vat Black 16 is to use existing indigo dyeing equipment to produce black or dark navy blue products with good light fastness but a vintage-style finish for denim and similar-style cotton products. It is a key specialized dye for the denim industry to extend into the black color series. It is not suitable for high-performance fields that have strict requirements for wet rubbing and chlorine bleach resistance.
