    • The process for producing microcapsules comprises forming capsules having a wall film composed of an amine-aldehyde polycondensate in a system in which a hydrophobic core substance is dispersed or emulsified in an acid aqueous solution containing an anionic colloidal substance, said anionic colloidal substance being an anionic water-soluble copolymer composed of acrylic acid, styrenesulfonic acid, and alkyl acrylate or alkyl methacrylate. The present invention decreases the large particles present in the capsule slurry, and provides microcapsule which are excellent in emulsification power, emulsification stability, particle size distribution, impermeability of capsule-wall film and workability.
    • 制造微胶囊的方法包括在疏水性核心物质在含有阴离子胶体物质的酸性水溶液中分散或乳化的体系中形成具有由胺 - 醛缩聚物构成的壁膜的胶囊,所述阴离子胶体物质为阴离子性 由丙烯酸,苯乙烯磺酸和丙烯酸烷基酯或甲基丙烯酸烷基酯组成的水溶性共聚物。 本发明减少胶囊浆料中存在的大颗粒,并提供乳化力,乳化稳定性,粒度分布,胶囊壁膜的不渗透性和加工性优异的微胶囊。

    • There is an image processing apparatus for use in a facsimile, electronic file, reader, digital copier, or the like. This apparatus has an image discriminating function and a high operating speed and comprises a pixel data input circuit and a circuit for processing the pixel data inputed from input circuit, in which the processing circuit has a discriminating circuit for detecting an amount of change in density level of the input pixel data for every pixel and discriminating the content of the image of the objective pixel data and a selector for selecting the processing mode of the projective pixel data in accordance with the result of the discrimination. Either half-tone processing mode or the non-half-tone processing mode is selected by the selector on the basis of the result of the discrimination. The non-half-tone processing mode is continuously selected for a predetermined period of time irrespective of the result of the discrimination.
