Yes. They are laminated with adhesive, just as laser videodiscs were.
The adhesive leaks O2 even when it's working well, and as it degrades
it leaks worse.
Hi
It sounds like the only way to deal with this is to store
disk in an innert environment. N2 or argon are reasonable
options. Only expose the disk to UV and O2 when actually
used to recover data. They should last for 1000's of years
this way.
