Abstract:
1. A method of producing a microparticulated 1,2-bis(3-methylphenoxy)ethane sensitizer composition for a thermal recording medium dispersed in water, which comprises: preparing a crystalline composition which comprises 1,2-bis(3-methylphenoxy)ethane as a main component and said composition comprising 50 ppm to 5.0 mass % of 1-(3-methylphenoxy)-2-(4-methylphenoxy)ethane and/or 1,2-bis(4-methylphenoxy)ethane as milling improving substances, and milling said crystalline composition with water, thereby producing a microparticulated dispersed 1,2-bis(3-methylphenoxy)ethane sensitizer composition.
