Abstract: The polyesters (I) are obtd. by reacting: (a) 5-50 pts. wt. linear or branched (cyclo)aliphatic di or polyhydric alcohol(s), (b) 2-40 pts. wt. at least di-basic aromatic carboxylic acid(s), (c) 0-40 pts. wt. 2-alkenyl-dicarboxylic acid anhydride(s), (d) 10-30 pts. wt. at least di-basic linear or branched aliphatic carboxylic acid(s), (e) 0-15 pts. wt. linear or branched aliphatic hydroxy-acid, (f) 0-15 pts. wt. linear or branched aliphatic polyamine with at least 1 prim. and at least 1 sec. or tert. amino gp., (g) 0-15 pts. wt. glycidyl ester of a branched aliphatic monocarboxylic acid or glycidyl ether of a branched aliphatic alcohol, and (h) 0-15 pts. wt. polyhydroxyamine. Also claimed are: (i) aq. dispersions of polyesters (I), (ii) polyester solns. contg. (I) with a solvent contg. water-miscible organic solvent(s) (pref. half-ethers of aliphatic diols) and water, (iii) processes for the prodn. of these dispersions and solns., (iv) electrophoretic coating baths contg. (I), and (v) a process for coating galvanised steel sheet in an electrophoretic coating bath contg. (I).

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: Aq. pigment pastes (I) are claimed, contg.: (A') an aq. dispersion of resin (A) with isocyanate-reactive functional gps.; and (B') an aq., solvent-free dispersion of a solubilised, capped isocyanate (B) which, in the case of cationic solubilisation, is produced from a polymeric or oligomeric polyisocyanate.

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.
