Abstract
The present invention relates to a heat-sensitive recording material having a high recording sensitivity, which is capable of providing excellent image quality even when recording is carried out at low energy, and causes reduced coating defects. The invention provides a heat-sensitive recording material obtained by forming, on a paper support, an undercoat layer and then a heat-sensitive recording layer, characterized in that: 1) the undercoat layer has at least two undercoat layers including a first undercoat layer and a second undercoat layer; and 2) the heat-sensitive recording layer has a thickness standard deviation of 0.30 or less, and also provides a method for producing the heat-sensitive recording material.
