    Abstract: The invention relates to paste resins containing (a) quaternary ammonium groups, (b) OH groups, (c) isocyanate radicals and (d) groups of the formula (I) in which R to R , independently of one another are hydrogen or a hydrocarbon radical having 1 to 10 carbon atoms, and X is hydroxyl or an isocyanate radical, the mean molecular weight (Mn) of these paste resins being from 500 to 10000. The invention furthermore relates to the preparation of these paste resins, to their use for pigment pastes and to these pigment pastes. water-thinable surface coatings, in particular electrodeposition coatings, which contain the pigment pastes according to the invention give defect-free surfaces and comparable coating thicknesses, even on different substrates.

    Abstract: Thermosetting coating compsn. comprises (A) oligomers and/or polymers contg. OH and/or epoxy gps. and (B) a mixt. of polycarboxylic acids contg. trimellitic acid. The mixt. (B) contains >=1 cpd. contg. ester groups and having formulae (I)-(III): In the formulate, R,R' and R" are opt. branched hydrocarbon gps. of valency 2-6, pref. 2, contg. 1-12, pref. 2-6C and opt. having up to 2 olefinic double bonds or contg. up to 3 ether bonds; x and y are 2-6, t is 1-5 and z and n are 0 or 1-5. The compsn. pref. contains as third component (c) a polymer of fluorinated vinyl monomers contg. is not >=2F, the ratio of A+B:C being 9:1-1:9, pref. 3:1-1:3. Used for coating a variety of substrates e.g. ceramics, wood, glass, concrete, plastics and esp. metals. The compsn. is highly reactive and can be applied as a powder or in soln. It cures at 120-200 degrees C pref. 120-180 degrees C within 30 mins. (cf. 180-200 degrees C for prior art compsns.) Compsns. contg. component (c) are partic. suitable for coil-coating. The compsn. is storage stable and (B) is soluble even in weakly polar solvent.
