WAERMEEMPFINDLICHES AUFZEICHNUNGSMATERIAL MIT FARBSTOFFVORLAEUFERBESTANDTEIL.

摘要

A support is prepared which has a high oil absorption degree (by JIS-P8130) of 10 seconds or less, by incorporating a highly oil absorbent pigment (e.g., CaCO3) into the support (e.g. of paper) or into a subbing layer thereon or using as support a porous film of high molecular weight. A coating solution is applied containing dispersions of electron-donating colorless dye precursor, an electron-accepting developer compound, and optionally a sensitizer these heat-fusible components having a low fused viscosity at 150 DEG C of 10 cp or less, preferably 5 cp or less. The coating solution is coated on the support to make a heat-sensitive recording material suitable for use in a facsimile machine.
