PURPOSE:To improve a color development property, by coating liquid containing a given surface active agent on one side of a microcapsule sheet. CONSTITUTION:A surface active agent has both a given hydrophobic group and hydrophilic atomic groups, such as di-1-dimethyl-3-methylpentyl sulfosuccinate, dihexyl sulfosuccinate, di-1-dimethyl-hyptylsulfosuccinate, and 0.0001-10pts.wt., based on 100pts.wt. a microcapsule solid matter, the surface active agent is mixed. In the mixture, a high-molecular material, whose molecular weight is a bout 1,000-10,000,000, such as stylenebutadien rubber latex, Arabia rubber, is used as a binder. The microcapsule sheet, which is excellent in high-speed coating apitude, is reduced in smearing at a coating and a processing time, and excellent in a coloring capacity, can be obtained through application of a given surface active agent. |
