Composite active golden yellow dye and application thereof

The invention discloses a composite active golden yellow dye and application thereof. The composite active golden yellow dye comprises two specific components shown as formula (I) and formula (II), and M in the components is H, Na, K or Li independently. The invention also provides application of the composite active golden yellow dye in nylon interwoven fabric dyeing and nylon-cotton interwoven fabric products.
