I have K25 and K64 slides dating back to the early 1960s. All are as good
today as they were when processed with no loss of colour or saturation or
shifting towards magenta or green. The cardboard mounts have also withstood
the test of time. The slides have been stored in darkness in the original
clear plastic / yellow lid boxes from Kodak, slotted slide boxes, or achival
plastic sleeves at 60 F or less. What might account for a shifting towards
magenta and green? .......... faulty manufacturing, improper storage.
All of my other slides from the same era..... Agfa and Perutz in particular
...... have shown horrible shifts in colour and have faded dramatically.
