Abstract: Amino-containing polymer systems which are suitable for the preparation of binders (vehicles) for printing inks can be obtained by synthesising a polymer or polymer mixture A from at least one compound from each of the following groups: (a) epoxides, carbonates and epoxide carbonates, (b) amines and (c) phenols, and at least partially neutralising the resultant polymer or polymer mixture A and transferring it into water, and optionally preparing a water-insoluble polymer B by polymerisation of ethylenically unsaturated monomers in the presence of the polymer or polymer mixture A.

Abstract: Aqueous synthetic resin dispersions containing A) an ionic resin, preferably a cationic resin, B) a masked polyisocyanate and C) a polymer comprising at least one free-radical-polymerizable ethylenically unsaturated monomer. These synthetic resin dispersions are used as binders in electrodeposition coating baths.

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 binders obtained by simultaneous reaction of A) urethanes or ureas, B) acrylic or methacrylic compounds containing hydroxyl groups, C) paraformaldehyde and D) if appropriate, polyols, wherein, in the case where no polyol D) is also reacted, the reaction is carried out in the presence of an acid ion exchanger, and in the case where a polyol D) is also reacted, the reaction is carried out in the presence of an acid ion exchanger or a strong acid. These binders are suitable as coating compositions which can be cured by electron beams or by UV light.
