<p>A heat-sensitive recording material that utilizes the color forming reaction between at least one basic dye and a developer that is capable of forming a color upon contact with said basic dye is characterized in that the heat-sensitive recording layer of said material contains both dihydroxydiphenyl ether represented by the formula (I): <CHEM> and a compound represented by the general formula (II): <CHEM> (where R is H or CnH2n+1, with n being an integer of 1 - 5). This heat-sensitive recording material has a sufficiently high sensitivity for color formation to make it suitable for use in a broad range of practical applications and it also exhibits enhanced keeping quality and whiteness.</p> |
