    摘要: An aqueous coating composition containing polymeric binder comprising particles of polyurethane-acrylic hybrid polymer dispersed in aqueous medium containing i) polyurethane polymer, preferably from 0.1 to 75 wt% ii) copolymer of ethylenically unsaturated addition copolymerisable monomers, preferably from 25 to 99.9 wt% characterised in that the polyurethane polymer comprises the reaction product of a) a polyisocyanate b) a compound containing at least two moieties reactive with the isocyanate moieties of the polyisocyanate c) a compound containing at least one dispersing moiety and at least one moiety reactive with the isocyanate moieties of the polyisocyanate d) a chain extender compound e) a urethane diol, being the reaction product of a cyclic carbonate and a compound containing an amino group and a further group selected from amino and hydroxy, said urethane diol comprising up to 80 wt% of the polyurethane polymer. The coatings have improved abrasion, water and stain resistance. Also an aqueous dispersion and a urethane prepolymer for use in making the dispersion.

    摘要: An aqueous dispersion of polyurethane-addition polymer hybrid particles, where the isocyanates used to make the polyurethane polymer portion of the particles comprise a mixture of aromatic polyisocyanate and aliphatic polyisocyanate wherein the aromatic isocyanate is free of sterically hindered isocyanate moieties. The dispersions are suitable for use in coatings, including varnishes, paints, inks and adhesives.
