This invention discloses a heat sensitive recording material having excellent transparency and anti-scratch property, which comprises on a support a heat sensitive layer and a protective layer successively, in which said heat sensitive layer is prepared by coating a composition containing an emulsified dispersion prepared by dispersing a color developer dissolved into an organic solvent slightly soluble or insoluble in water and microcapsules containing a colorless or light colored electron donating dye precursor and then drying the coat, and said protective layer is comprised of at least a modified polyvinylalcohol with silicon and a colloidal silica; a preferred mixing ratio of the modified polyvinylalcohol with silicon to the colloidal silica is 0.5-3 calculated by parts by weight.
