http://www.mam-a.com/products/gold/archive.html make gold substrate
CD-R which are supposed to last for a hundreds of years (ofcoarse CD-R
have not been around for that long), So who knows. Gold substrate are
supposed to last long because silver with corode over time.
There are other companies that make Gold substrate CD-R.

Sun light and air can both degrade CD-R so you can look into dark
nitrogen storage for your archival disks.
