Aqueous synthetic resin dispersions, process for preparation and use thereof

摘要

The aq. synthetic resin dispersions (I) contain: (a) an ionic epoxy resin derived from bisphenol A substd. with aralkyl gp(s)., (b) a capped polyisocyanate, and (c) a polymer of radically polymerisable olefinic monomer(s). Also claimed are: (i) a process for the prodn. of (I) from a mixt. of vinyl monomer (c), resin (a) and blocked di or poly-isocyanate (b), by converting the mixt. into an aq. dispersion and polymerising with a radical initiator; and (ii) articles coated with the dispersion (I).
