A german Ilford employee stated this repeatedly at another forum. And you can test it for yourself - a bit of Alkali solution should be enough to trigger the hydrochinone... but MG4 wonīt react to it.

So far I have used only one paper of this type - Fomaspeed Variant 3. It is much faster that MG4, it gets very soft after 2 years of storage and an undeveloped piece blackens within a few hours if exposed to sunlight.

BTW - a very nice paper.
