<P>PROBLEM TO BE SOLVED: To provide a microcapsule, which can freely design various capsule performances (live preservation property, heat sensitivity, coloring density, texture fog, humidity dependence property, and the like), their manufacturing method and a recording material using them. <P>SOLUTION: In a water system medium, an oil drop containing a monomer having at least a coloring component and a monomer having an ethylene unsaturated double is dispersed in a water system medium, a coloring component intensive microcapsule featured to form a microcapsule wall on an oil drop interface by polymerizing a monomer having polymerization having an unsaturated double bond by dispersing an oil drop containing a monomer having at least coloring component and an ethylene unsaturated double bond in an aqueous medium. Its manufacturing method and a heat sensitive recording material using that, as the monomer having the ethylene unsaturated double bond, a multi functional monomer having two or more pieces of ethylene unsaturated double bonds should have preferably contain 90 mol% or under. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
