Also, the pAP dyes will very likely be very pH sensitive. This is due to the acid nature of the -OH group instead of a -NH2 group. Again, couplers were not designed to allow for this ionization.

Good luck guys. And Athril, lose the dust and lint!

PE thanks for your insight/advice. Always helpful.
