.....how long can exposed photo paper used as negative be stored before
processing?
Any special storage requirements?

Dennis,
The latent image in black & white emulsions is stable enough at normal room
temperatures to remain virtually unchanged for several months....at low
temperatures/ humidity, several years. However, high temperature/
humidity and exposure to chemical fumes can cause rapid deterioration and
complete loss of latent image within days (M J Langford-1977).
NB colour materials are much less tolerant/ forgiving.
