Visible Opaque Dyes are designed to block all light within the visible spectrum but still allow light to be transmitted outside of this visible region, such as the Ultra-Violet Near IR and IR Ranges. 

These dyes are often used in covert security applications such as the production of hidden barcodes and such.
