Abstract
A heat-sensitive color-developing layer of a heat-sensitive recording medium and a coating liquid for forming the heat-sensitive color-developing layer each contain a leuco dye, a color developing agent and a polyvinyl alcohol resin containing an acetoacetyl group and a sulfonic acid group or a combination of a polyvinyl alcohol resin containing an acetoacetyl group and a polyvinyl alcohol resin containing a sulfonic acid group. Therefore, the heat-sensitive recording medium and the coating liquid for forming the heat-sensitive color-developing layer are excellent in light resistance, and free from unintended color development and discoloration even when exposed to ultraviolet radiation.
