Abstract
A sensitizer particle dispersion containing stearic acid amide, a preparation method thereof, a mixed dispersion composition for a thermosensitive recording layer using the sensitizer particle dispersion, and a thermosensitive recording medium using the mixed dispersion composition are provided. The sensitizer particle dispersion can be safely prepared under atmospheric pressure by mixing stearic acid amide and another sensitizer at a mass ratio of 95:5˜51:49; co-melting the mixture by heat in emulsifier-dispersed water, whereby the mixture is unified and emulsified into particles, or emulsifying the co-melted mixture of stearic acid amide and the other sensitizer unified by co-melting the mixture by heat, into particles in emulsifier-dispersed water; and quenching the obtained emulsified dispersion, thus crystallizing sensitizer particles from the emulsified particles.
