Thermal sheet production process

摘要

In a process for the production of thermal pane of the type having an electrically conductive circuit on a glass pane, a plurality of electrically conductive inks are produced, each of which has different resistivity. On at least one side of the glass pane a continuous circuit having a constant section along its length is formed by layering each of the inks along the length of the circuit at predetermined locations so that the resistivity of the circuit changes along the length thereof.
