Abstract
A heat-sensitive recording paper is disclosed. The paper is comprised of a support base which is made of a paper having a density 0.9 g/cm.sup.3 or less and a heat-sensitive recording layer coated on the support base. The surface of the heat-sensitive recording layer has an optical contact ratio of 7% or more. By utilizing the particularly disclosed support base paper and adjusting the optical contact ratio of the surface of the heat-sensitive recording layer, the resulting recording paper can give high heat conductivity between the surface of the recording layer and a recording element. Accordingly, the recording paper has a fast response speed and can produce a high density image without disadvantages such as increased fog formation.
