ABSTRACT:
A pressure-sensitive recording sheet, comprising: a synthetic resin support sheet; a color developer layer coated on one face of the support sheet; a color former layer overcoated on the color developer layer and containing a microcapsulated color former; a first water-impermeable layer adhering on the other face of the support sheet through an adhesive; and a transparent second water-impermeable layer covering directly over the color former layer; and wherein the outer peripheries of the first and second water-impermeable layers are liquid-tightly closed to protect the support sheet, the color developer layer and the color former layer from attack by any aqueous liquid. The pressure-sensitive recording sheet or the support sheet is shaped to have a horseshoe-like contour to be used as an occlusion pressure detecting sheet. A wax coating layer may be provided on at least one surface of the occlusion pressure detecting sheet to record the dental arch pattern.
