    • PURPOSE:To form a resin film having no thick spot, by applying molten resin to mold release paper preheated in the width direction thereof. CONSTITUTION:In coating mold release paper with heated molten resin, said mold release paper is heated in the width direction thereof (pref., a means for heating said mold release paper while dividing the width direction is used) to be coated with said resin. EFFECT:The cooling of the resin during coating can be prevented and, because there is no abrupt lowering in viscosity, a thin film is obtained. In addition, a resin temp. can be set to a relatively low temp. and this method is especially suitable in using thermosetting resin.
    • 目的:为了形成没有厚点的树脂膜,通过将熔融树脂施加到在其宽度方向上预热的脱模纸。 构成:在具有加热的熔融树脂的涂布脱模纸中,将所述脱模纸在其宽度方向上加热(优选的是用于加热所述脱模纸,同时使用宽度方向分开),以涂覆所述树脂。 效果:可以防止涂布时树脂的冷却,并且由于粘度没有突然降低,所以获得了薄膜。 另外,树脂温度 可设定相对较低的温度。 该方法特别适用于使用热固性树脂。

    • PURPOSE: To provide a pressure-sensitive recording sheet which has an uniformly- coated surface, by a method wherein a free fall perpendicular curtain is formed using an applying liquid, in whch physical properties, such as static surface tension, is adjusted into several values, to produce the pressure-sensitive recording sheet.
      CONSTITUTION: Through addition of a surface active agent to a liquid, whose main component is a microcapsule, being covered with a high molecular cell material being insoluble in both water and an oily liquid, and in which the microcapsule is dissolved or dispersed together with a binder and a protective agent, an oily liquid, in which a basic colorless color former is dissolved, is adjusted so that the static surface tension of the liquid is below 42dyne/cm, a rise in a surface tension from a static surface tension due to a surface expansion is below 5dhne/cm, and the passage through 50-mesh screen is 98%. The applying liquid 1 so obtained is caused to flow out through a slit 6 as it is fed to a tank 2 by means of a quantative pump to form a free fall perpendicular curtain being uniform in the direction of a width. Air current is shut off by an air-shielding plate 11 to convey a web 9 and the applying liquid 1 is applied to the web 9.
