Abstract: The invention relates to the use of crosslinked polymer microparticles having an average particle size of at most 5 mu m and a glass transition temperature (Tg) of at least +30 DEG C. in aqueous paint preparations as filler and/or as partial substitute of white pigments, in particular of titanium dioxide. Among other things, the corresponding paints show increased spreading power, less tendency for sedimentation and reduced crater formation.

Abstract: 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).

Abstract: Curable compounds carrying basic nitrogen groups and essentially comprising structural units derived from A) a compound containing on average at least one terminal 2-oxo-1,3-dioxolane group per molecule, with B) a disecondary amine containing hydroxyl groups in the beta -position to the secondary amino groups, it also being possible for this amine to contain blocked primary amino groups, and optionally C) a bifunctional amine containing at least one free primary amino group and optionally at least one secondary amino group, are used, in particular, in surface coating preparations, especially in electrodeposition coating compositions. The coatings obtainable using these compositions have, in particular optimised interlayer adhesion.

Abstract: Stable, aq. epoxy resin dispersions (I) contain (A) an epoxy resin obtd. by the condensation of (A-1) cpd(s). contg. at least two epoxide gps.; with (A-2) an aralkylated polyhydroxy-aromatic obtd. by reacting (A-2-1) polyhydroxy-aromatics with (A-2-2) aromatics contg. an alkylene gp.; (B) a dispersant; and (C) water. Also claimed are (i) the prodn. of (I) by reacting (A-1) with (A-2) to give an epoxy resin (A), dispersing (A) in water with addn. of emulsifier (B) and olefinic monomer(s) (D-1), and polymerising in presence of a radical initiator; and (ii) coatings obtd. by applying dispersion (I) to a substrate, followed by hardening.
