摘要： This invention discloses a heat sensitive recording material having a heat sensitive layer on a support; either of a color forming material or a developer which are contained in the heat sensitive layer is encased in a microcapsule. Since a plasticizer for a wall material of the microcapsule and a compound having an effect to depress the melting point of at least one member out of developers, a color forming reaction is carried out smoothly under a recording condition, therefore, a density of an obtained image is sufficient. Especially good results are obtained when a macromolecule substance selected from a group of polyurethane, polyurea, polyamide, polyester and polycarbonate is used as a wall material of the microcapsule. A coloring reaction assistant may be contained in any place of the heat sensitive layer.A preferable plasticizer can be selected from a group of phenols, alcohols, ureas, sulfonamides, carbamates and aromatic methoxy compounds.
