PURPOSE:To obtain the titled soft, porous film for rain coat and the like by a method wherein vinyl chloride resin powder being dispersed in water along with plasticizer, water repellent is applied to the base material with surface releasability to form a coating film and the film is heated, melted then cooled. CONSTITUTION:A hundred weight parts of vinyl chloride resin powder are dispersed in water along with 20-80 weight parts of plasticizer (such as dioctylphthalate etc.) and 0.1-10 weight parts of repellent (such as silicone emulsion etc.), then, this dispersion liquid is applied to a base having surface peeling properties (such as release paper etc.) to form a coating film. The base provided with this coating film is heated in a hot stove etc. water is volatiled, particle surface of polyvinyl chloride resin powder is melted, neighboring particle surfaces stick to one another, then, cooled to obtain the desired film. |
