Do holograms fade evetually?

Question

A friend of mine gave me a hologram several years ago ( probably close to 10 years now) I used to have it on my wall, with the special light shining on it, and it looked great. Then I moved and it was in storage for probably 5 years. The other day, I took it out of storage and shone the light on it, and could barely see it anymore.

Answer 1

All printed materials fade after extensive exposure to ultraviolet light (sunlight). If the ink was fluorescent (glows under a black light), that has an even shorter life than average pigments, and will decompose naturally, even without being exposed to UV light.
