    摘要: What are disclosed are methods for making an aqueous dispersion of a synthetic resin copolymer, said dispersion having high pigment binding capacity and adaptable to use in the preparation of printing inks or pastes, said copolymer comprising a predominant amount of water insoluble monomers together with from 3 to 8 percent by weight of an acid component which is a water soluble acid or salt, which method comprises gradually adding said water insoluble monomers, together with a portion of said acid component, to an aqueous medium containing the balance of the acid component in the form of a dissolved water soluble salt; aqueous synthetic resin dispersions made by these methods; and printing inks comprising such an aqueous synthetic resin dispersion which has been neutralized and combined with such an amount of an organic solvent as converts the dispersion into a solution or colloidal dispersion of the synthetic resin.

    摘要: What is disclosed is making highly concentrated, bimodal, aqueous synthetic resin dispersions by the emulsion polymerization of ethylenically unsaturated monomers, in the presence of emulsifiers and free radical-forming initiators, by adding to a first latex containing a first dispersed synthetic resin and an aqueous phase, a second latex containing a second dispersed synthetic resin and an aqueous phase and a monomer phase containing a free-radically polymerizable monomer, and then polymerizing the monomer, the average size of the particles of said first resin differing by a factor between 2 and 15 from that of the particles of second resin, the total weight of the resins and monomers representing 100 parts by weight, and the total weight of the aqueous phases representing not more than 70 parts by weight.
