d)If thermal paper touches anything which includes phthalic acid ester plasticizer for a long period, it can reduce the image formation ability of the paper and can cause the printed image to fade. When storing thermal paper in a card case or sample notebook, be sure to use only products made from polyethylene, polypropylene, or polyester.
e)If thermal paper touches diazo copy paper immediately after copying, the printed surface may discolor.
