摘要： A method for producing a material containing a sensitizer dispersed therein, characterized in that a sensitizer for a thermal recording article in an aqueous emulsifying and dispersing agent solution is emulsified and converted to a fluid containing fine particles while heating the solution and melting the agent, and then rapidly cooling the resultant material containing emulsified and dispersed fine particles to crystallize the particles, wherein said sensitizer is selected from the group consisting of 1,2-bis (phenoxy) ethane, 1,2-bis (3-methylphenoxy) ethane, 1,2-bis (4-methylphenoxy) ethane, p-benzylbiphenyl, di-p-methylbenzyl oxalate and β-naphtyl benzyl ether. The method allows the production of a material in the form of fine particles containing a sensitizer dispersed therein with good volume efficiency in a short operating time, and said material is excellent in storage stability and can provide a thermal recording article which exhibits high sensitivity, is almost free from the stain of a ground portion, and exhibits good preservation stability of a recorded image.

摘要： The invention provides a heat-sensitive recording material, which is highly sensitive, is almost free of staining on the background, and gives a recorded image excellent in stability during storage, by using a finely divided sensitizer dispersion excellent in shelf stability produced in a short time with high volumetric efficiency. The invention relates to a method of producing a sensitizer dispersion, which comprises emulsifying and finely dividing a heat-sensitive recording sensitizer by melting under heating in an aqueous emulsifying dispersant, and then crystallizing the finely divided emulsified dispersion under rapid cooling, wherein the sensitizer is at least one member selected from the group consisting of 1,2-bis(phenoxy)ethane, 1,2-bis(3-methylphenoxy)ethane, 1,2-bis(4-methylphenoxy)ethane, p-benzylbiphenyl, di-p-methylbenzyl oxalate, and β-naphthyl benzyl ether.
