    摘要： The invention provides an aqueous resin dispersion which can form a coating film excellent in adhesion to a polypropylene base material, and water resistance, and has excellent particle stability. Specifically, it provides an aqueous resin dispersion in which an olefin polymer (A), and a polymer (C) containing a constituent unit derived from a radically polymerizable monomer (B) represented by the following general formula (1) are dispersed in an aqueous medium. (In the general formula (1), R is a hydrogen atom or a methyl group, and X is a straight chain or branched alkylene group having 3 to 5 carbon atoms; and n is an integer of 1 to 20.)

    摘要： The present invention provides a durable, external surfactant free, cationic, water based jet ink polymer which when formulated into an ink jet ink results in a printing that has an excellent adhesion to metal or plastic substrates. Such a jet ink polymer is suitable performance replacement of solvent soluble polymers currently in commercial use. The hybridized copolymer comprises a hydrophobic functional polymeric backbone comprised of a polysiloxane polymer, a polyolefin polymer, or a functional polyvinyl polymer. The hybridized copolymer also comprises a plurality of copolymeric side chains attached to the backbone, comprising a polymerizable amine-containing unsaturated monomer, and a polymerizable unsaturated monomer. The use of the inks of the present invention enhances performance criteria such as print-head open time, ink stability, and resistance to typical water based cleaners.
