    摘要: The invention relates to a process for preventing the gelation of concentrated aqueous photoactivator solutions containing sulfonated zinc or aluminium phthalocyanines. The process comprises passing a crude solution containing these compounds, when preparing the solutions, through a semipermeable asymmetrical membrane having a pore diameter of 1 to 500 .ANG.. This membrane consists of a basic structure of cellulose acetate, polyacrylonitrile or a copolymer of acrylonitrile and other ethylenically unsaturated monomers. This basic structure is modified in specific manner with ionic groups. The concentrated photoactivator solutions so obtained have excellent storage stability, do not gel, and contain exceedingly small amounts of inorganic and organic impurities.

    摘要: A process for the preparation of formulations of water-soluble organic dyes starting from an aqueous salt-containing suspension of the untreated dye and using membrane separation methods, which process comprises substantially freeing the aqueous suspension of the untreated dye from by-products and reducing the salt concentration by more than half in a first membrane separation treatment, then diluting the dye suspension in a further optional step and effecting deionization and concentration in a second membrane separation treatment and converting the concentrate so obtained into a liquid or solid commercial formulation. This multi-step membrane separation process, e.g. ultrafiltration combined with hyperfiltration, results in a high rate of permeation through the membrane and avoids operating problems caused by membrane clogging.
