초록 ▼

The invention relates to binders for cathodically depositable coating compositions for the electrocoating lacquering process using cationic synthetic resins, which binders have been obtained by polymerizing (A) 5 to 95% by weight of ethylenically unsaturated polymerizable monomers in the presence of (B) 95 to 5% by weight of a cationic synthetic resin in an aqueous phase, the total amount of the components (A) and (B) being 100%. Esters of acrylic acid and/or methacrylic acid are preferable for use as component (A). The invention also relates to a process for preparing the binders and to their use for cathodically depositable electrocoating lacquers.

In a binder for cathodically depositable coating compositions containing at least a cationic synthetic resin as a binder and a crosslinking agent and which are depositable on application of a voltage onto an electrically conductive substrate connected as a catode and which produce crosslinked coatings after stoving having surface quality and good corrosion protection, the improvement consisting essentially of an aqueous binder dispersion product obtained by emulsion polymerization: (A) 5 to 95% by weight of ethylenically unsaturated polymerizable monomers in the presence of, (B) 95 to 5% by weight of a cationic synthetic resin consisting of a saturated cationic synthetic resin in an aqueous phase, the total amount of components (A) and (B) being 100%, wherein component (A) is a mixture of (a1) 10 to 99% by weight of an alkyl ester of acrylic acid, an alkyl ester of methacrylic acid or a mixture thereof said esters having an alkyl group containing 1 to 4 carbon atoms; (a2) 1 to 30% by weight of ethylenically unsaturated compounds having functional groups selected from the group consisting of derivates of esters of methyacrylic acid containing hydroxyl groups, esters of methacrylic acid having epoxide groups, esters of methacrylic acid having tertiary amino groups, esters of acrylic acid containing hydroxyl groups, esters of acrylic acid having epoxide groups, esters of acrylic acid having tertiary amino groups and mixtures thereof; and (a3) 0 to 80% by weight of other ethylenically unsaturated polymerizable monomers selected from the group consisting of aliphatic vinyl compounds, vinyl esters, vinyl esters of a1), (a2) and (a3) being 100%, and component (B) is a resin containing epoxide groups said resin comprising bisphenol A as a reactant, and said resin having been reacted with compounds selected from the group consisting of amines, ammonium salts, sulfide/acid mixtures, phosphine/acid mixtures or mixtures thereof.
