Abstract:
PCT No. PCT/EP97/00150 Sec. 371 Date Jul. 20, 1998 Sec. 102(e) Date Jul. 20, 1998 PCT Filed Jan. 15, 1997 PCT Pub. No. WO97/26289 PCT Pub. Date Jul. 24, 1997An aqueous binder vehicle dispersion and coating media, which can be used for multi-layer coating, wherein the dispersion is obtainable by the reaction of I. 20 to 97% by weight of a polyurethane(-urea) resin containing groups which are reactive towards a chain extender IV), having a number average molecular weight (Mn) of 1000 to 10,000, and 8 to 80 milliequivalents per 100 g of ionic groups, groups which can be converted into ionic groups and/or hydrophilic groups, II. 0 to 30% by weight of a polyester resin having a number average molecular weight (Mn) of 500 to 5000, and having the same groups as in I) which are reactive towards IV), and III. 3 to 80% by weight of a (meth)acrylic copolymer containing 0 to 40 milliequivalents per 100 g of ionic groups, groups which can be converted into ionic groups with the same charge as in I) and/or hydrophilic groups, having the same groups as in I) and II) which are reactive towards IV), wherein at least 50% by weight of III) has been produced in the presence of at least part of components I) and/or II), with IV. one or more chain extenders, and conversion into the aqueous phase.
