PURPOSE:To obtain a heat-sensitive recording sheet with pictures having improved stability by using an usually colorless or light color dye precursor and a developer composed of benzyl p-hydroxybenzoate and benzyl p-benzyloxybenzoate. CONSTITUTION:Benzyl p-hydroxybenzoate (100wt%) and benzyl benzyloxybenzoate (15-60wt%) are separately or concurrently ground into fine particles by a grinder. In the same way, a dye precursor, a binder, pigment, etc., are ground into fine particles by a grinder, and the mixture is mixed with various additives as needed. These mixtures are mixed together and made into a heat-sensitive recording sheet. In this case, the percent (%) stands for the used proportions of constituent developers. |
