hot sThermal PaperIt is a special fine paper that is coated with a
material formulated to change color when exposed to heat.It is used
in thermal printers, particularly in inexpensive or lightweight
devices such as adding machines, cash registers, and credit card
terminals.The surface of the paper is coated with a solid-state
mixture of dye and a suitable matrix; a combination of a fluoran
leuco dye for example. When the matrix is heated above its melting
point, the dye reacts with the acid, shifts to its colored form,
and the changed form is then conserved in a metastable state when
the matrix solidifies back quickly enough. The reactant acid in
thermal paper is often bisphenol A (BPA).Usually, the coating will
turn black when heated, but coatings that turn blue or red are
sometimes used. While an open heatsource, such as a flame, can
discolor the paper, a fingernail swiped quickly across the paper
will often generate enough heat from friction to produce a mark.
Multicolor thermal paper first became available in 1993 with the
introduction of the Fuji Thermo-Autochrome (TA) system.
