    • A peel-apart type instant film unit comprising an image receiving sheet separably adhered in a heat sealing manner to a mask member which is peeled apart from the former after the development thereof. There is provided therebetween a weak sealing layer comprising an adhesive layer of a thermoplastic polymer having hydrophilic groups and a separating layer which is alkali resistant and has a good separation property relative to the adhesive layer. The weak sealing layer can provide an easy separation between the separating and adhesive layers so as perfectly to transfer the adhesive layer to the image receiving sheet to provide a fine appearance and a writeable image frame on the image receiving sheet. The mask member is made of any polyethylene compounded paper sheets and is provided with a processing liquid-resisting layer inside the weak sealing layer for the purpose of preventing the permeation of processing liquid thereto.
    • 一种剥离型即时胶片单元,其包括以热封方式可分离地粘附到在其显影之后从前者剥离的掩模构件的图像接收片。 在其间设置有弱密封层,该密封层包括具有亲水基团的热塑性聚合物的粘合剂层和耐碱性并且相对于粘合剂层具有良好分离性能的分离层。 弱密封层可以在分离层和粘合剂层之间提供容易的分离,从而完美地将粘合剂层转移到图像接收片材,以在图像接收片材上提供精细的外观和可写入的图像帧。 掩模构件由任何聚乙烯复合纸制成,并且在弱密封层内设置有防止加工液渗透的处理液层。

    • A closing tape prevents winding looseness of a roll photo film and a light-tight sheet which are wound around a spool. After an adhesive agent layer formed on one end of the closing tape is adhered to a surface of the light-tight sheet, an adhesive agent layer formed on the other end of the closing tape is adhered to a surface of the closing tape. The adhesive agent layer consists of multiple adhesive dots. The respective dots are formed by heat sensitive adhesive agent filled in the respective cells of a gravure roll to coat on the closing tape by gravure coating. Adhesive force is stabilized due to uniformity in size and thickness of the dots. Moreover, the cells are provided at same intervals and heat sensitive adhesive agent having optimum viscosity is used, so that the adjacent dots are prevented from connecting each other.
    • 闭合带防止卷绕在卷轴上的卷筒胶片和不透光片材的卷绕松动。 在封闭带的一端形成的粘合剂层粘附到不透光片的表面之后,形成在封闭带的另一端上的粘合剂层粘附到封闭带的表面上。 粘合剂层由多个粘合剂点组成。 相应的点由填充在凹版辊的各个单元中的热敏粘合剂形成,以通过凹版涂布涂覆在封闭带上。 由于点的尺寸和厚度的均匀性,粘合力被稳定。 此外,以相同的间隔设置电池,并且使用具有最佳粘度的热敏粘合剂,从而防止相邻的点彼此连接。
