I knew this stuff was going to be a problem years ago when I pulled some receipts out of my wallet and they had turned basically totally white (except for the advertisements on the back of the receipt...). The thing is that I can't figure out how they faded in my wallet as temps shouldn't have been much above body temp or MAYBE 10 degrees higher at the most - I don't keep it in the sun, hot car or similar.
I went back through some receipts from 3-5 years ago that have been in a file drawer and they have faded to the point that they are unreadable and they have been in climate controlled rooms (80 degree max, 65 min).
I was wondering if anyone else had issues like this and knows why they fade even when high temps aren't present.
When a flame is applied the paper turns blackish but often fades to light grey after cooling. I haven't figured out how this stuff works yet- anyone know the deal?
I would think businesses who store these for tax purposes would hate these things as they degrade so quickly. Sure makes proof of purchase for returns more difficult in some cases. Anyone know what businesses do to deal with this - both for storage/tax purposes and for customer issues?
