ABSTRACT:
By using, in production of microcapsules, a partially esterified product of a styrene-maleic anhydride copolymer as an emulsifier, advantages are obtained that coloring of emulsion can be reduced/prevented at the time of emulsification and, when the microcapsules produced are used in a carbonless copying paper, a desensitizer component is not transferred to a lower paper and accordingly color development is not hindered.
