This ink set, known here as the IRIS "Longevity Inks" were tested by
Henry Wilhelm and were shown to be less stable than the earlier IRIS
"Fine Art" ink set. Originally distributed by IRIS, they have been
withdrawn from the market because of their extremely poor
light-stabilty. Ilford is well aware of all this but they nevertheless
continue to advertise/market the inks in Europe.
