A protective coating is applied to a thermally reactive material layer in laminate manner. The coating includes a fluorocarbon sizing agent which causes beading of any adverse material and prevents penetration thereof into the thermally reactive material. A combined color developing and dye formulation includes bisphenol, wax, clay and dye in a binder of polyvinyl alcohol which effects a spreading of any adverse material on the surface of the coating.

Protective coating for thermosensitive material

A thermosensitive sheet includes a support layer or substrate, a thermally reactive coating or layer on the substrate, and an impervious cellulose based layer on the thermally reactive coating. The thermally reactive coating acts as an adhesive for laminating the cellulose based layer and the substrate. A method of providing the protective barrier is also disclosed.

Protective barrier and method of providing same for thermosensitive sheet

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.
