Uncoated Teslin SP substrate can act as a receiver sheet with certain carbonless (CB) forms. Scotchmark® CB forms from 3M have performed well with Teslin substrate as a receiver. The initial blue-black color fades to red-violet in fluorescent lighting, but the image remains readable after six weeks of office exposure (40-45 hours light time/week). PPG Industries does not have information concerning image stability under outdoor exposure.
