MANUFACTURING METHOD FOR REVERSIBLE IMAGE DISPLAY MEDIUM

摘要

PROBLEM TO BE SOLVED: To provide a manufacturing method for a reversible image display medium capable of displaying an image of high contrast and good quality with a developer moving smoothly in each container cell as well as a method for the medium of which two substrates are easily removable so as to use repeatedly. SOLUTION: The manufacturing method for a reversible image display medium of which dry process developer DL including at least two kinds of dry process developing particles having triboelectric property, different electrostatic charge polarities and different optical reflection densities from each other is put in cells 16 between two substrates 11 and 12 is as follows; one side of the first substrate 11 is prepared to have projecting and recessing surface including recesses for the cells 16; After the developer DL is put in the recesses on the one side of the first substrate, the second substrate 12 is glued to the one side of the first substrate 11; the adhesion is performed by decompressing the inside of the cell 16 so as to contact the two substrates tightly to each other or by gluing them with a hot-melt adhesive of which appearing temperature of adhesiveness is lower than softening temperature of the developer or with a reactive hot-melt adhesive.
