    Abstract: A liquid coating composition based on a polymer containing acetoacetate groups and a polyamine in the form of the corresponding aldimine or ketimine, the polymer containing acetoacetate groups being obtained by reacting a polyepoxide containing hydroxyl groups, or a polyepoxide which is partially or completely reacted with monocarboxylic acids, with acetoacetic acid derivatives. These liquid coating compositions are suitable in particular as binders in two-component fillers for automotive refinishing or as two-component primers.

    Abstract: A process for preparing polymer non-aqueous dispersions to be formulated together with a binder component in coating compositions, which comprises the steps of: (1) emulsion polymerizing a hydroxy group containing .alpha.,.beta.-ethylenically unsaturated monomer, a polyfunctional .alpha.,.beta.-ethylenically unsaturated monomer and an .alpha.,.beta.-ethylenically unsaturated monomer different therefrom by using a water-soluble polymerization initiator, preferably a persulphate, in a soap free system or in the presence of an ester group containing anionic or cationic surfactant; adding an organic solvent, preferably comprising an amphipathic organic solvent, to a resultant polymer aqueous dispersion; and then adding a basic compound catalyst when the anionic surfactant is used or an acidic compound catalyst when the cationic surfactant is used, to thereby hydrolyze completely said surfactant and water-soluble polymerization initiator at a temperature not exceeding 95.degree. C. as in the condition of suspension; (2) adding an acidic or basic compound to said suspension to neutralize said basic or acidic compound catalyst: then after adding dispersion stabilizing resin, further adding an amine salt of organic acid, followed by leaving said suspension to stand to separate into organic and water layers; and isolating the organic layer from the water layer; and (3) removing residual water in the organic layer. The resultant polymer nonaqueous dispersion comprises polymer particles having a total ionic group concentration (I) less than 2.times.10.sup.-5 mol/g particle, a hexane tolerance (HT) from 5 to 40 exclusive and a degree of swelling in acetone (S) less than 10, and used with a binder component comprising a polyol resin and a curing agent for preparing coating compositions.
