Multiple copy thermal record sheet |
摘要 |
A thermal-sensitive record sheet copy system provides multiple copies by applying a coating to one record sheet. The single coating formulation includes ingredients which react to heat to provide a tacky condition having a desirable adhering property and thereby produce images on the two sheets. The coating includes a binder of synthetic polyterpene in the mixture in combination with a thermochromic dye and a phenolic resin.
