Aqueous coating compositions with improved transparency

一种透明度和光雾改进的水性涂料组合物，含有：(a)含水载体介质；(b)透明氧化铁颜料颗粒，由成分(c)加以稳定；(c)多种丙烯酸类共聚物颜料分散剂的混合物；(d)成膜聚合物粘结剂；以及(e)粘结剂所用的交联剂。 An aqueous coating composition having improved transparency and reduced haze containing: (a) an aqueous carrier medium; (b) transparent iron oxide pigment particles stabilized by (c) a mixture of acrylic copolymer pigment dispersants of (i) an acrylic copolymer dispersant having a hydrophilic stabilizing segment and a hydrophobic adsorbing segment having acid groups attached thereto; and (ii) an acrylic copolymer dispersant having a hydrophilic stabilizing segment and a hydrophobic adsorbing segment having phosphate groups attached thereto; and (iii) an acrylic copolymer dispersant having a hydrophilic stabilizing segment and a hydrophobic adsorbing segment having alkyl amino groups and preferably benzyl groups attached thereto; (d) a film forming polymeric binder; and (e) a crosslinking agent for the binder. Pigment dispersions of the forgoing acrylic copolymer dispersant combination and process for forming the dispersions also are part of this invention.
