Ilford's Technical information sheet on the digital silver papers here:

My bottom line take on it is that this is a fairly standard silver gelatin
paper.  As with the older materials, processing differences will affect how
it ages.  Assuming the processing here was not sloppy, my best guess is
that these differences would not have a significant impact on the tests at
this stage.

At any rate, here are a few notes from the Ilford materials:

"ILFORD GALERIE FB DIGITAL SILVER is a premium
quality black and white, panchromatic photographic
paper that has a neutral image colour. It is coated onto a
double weight Baryta coated fibre base. Overall Product
weight is 310gsm.
...

"The
results are equal to those seen when using conventional
black and white printing materials and exposing
equipment."


"OPTIMUM PERMANENCE
DISH PROCESSING
The standard fixing and washing recommendations will
give excellent print permanence for all commercial needs.
When optimum permanence is needed, perhaps for
archival storage of prints, the following fixing and
washing sequences ...

Ilford also recommends toning for more print protection:
"...  It
is recommended that prints made for display are toned to
protect them from the oxidising gases that are found in
many environments."


[For long term storage Ilford also has recommendations.]

"Briefly
the main conditions are; freedom from chemical
contamination, either airborne or from storage containers,
also protection from high levels of ultra-violet radiation,
particularly sunlight but also fluorescent lighting. ..."
