When ink is exposed to sunlight it can be bleached out by it due to the UV-rays of the light. The energetiv UV-light is able to split up oxygen molecules O-O into so called radicals O2 --UV--> 2 O. this atomar oxygen is very reactive an destroys the ink, more chemically: it oxidises the ink.

It's in a way quite the same when you're washing clothes with bleach to remove tomatoe taints or so - there are formed radicals from the bleach which oxidise the color molecules of the tomatoe and destroy it this way to leave a bright piece of cloth after wash.
