摘要： In a thermal recording sheet including a substrate having thereon a thermal color developing layer containing colorless or pale colored basic achromatic dye and an organic color developer, the thermal color developing layer contains aluminium hydroxide and a urea-formaldehyde resin pigment. The thermal recording sheet is small in abrasion of the recording head and adherence of depositions to the head even after long-run recording, and friction staining in unrecorded portion due to the recording head and change in gloss in unrecorded portion during recording are small.
