摘要： The invention provides a dispersant for an aqueous dispersion of boehmite particles which comprises a compound having an anchoring moiety linked to a polymeric hydrophilic moiety, the anchoring moiety containing at least one acid and/or hydroxy group and having overall acidity or neutrality and the polymeric moiety having a lower affinity for a boehmite surface than the anchoring moiety. The anchoring moiety preferably contains at least two acid groups, preferably carboxylic acid groups, attached either in a [1,1], [1,2] or [1,3] relationship and is linked to the polymeric moiety, which is preferably derived from acrylamide or methacrylamide monomer units, preferably by a sulfur atom. The dispersant can reduce the viscosity of the boehmite dispersion and the tendency of the boehmite dispersion to increase in viscosity and/or form a gel or a yield stress material following periods of high shear stress. It may be used, for example, as a component of a coating material, a ceramic, paint, refractory material, filler, or in particular in an inkjet recording paper or film, wherein good porosity and gloss is maintained by the use thereof.
摘要翻译：本发明提供了勃姆石颗粒的水分散体的分散剂，其包含具有与聚合亲水部分连接的锚定部分的化合物，所述锚定部分含有至少一个酸和/或羟基并具有总体酸度或中性，并且聚合部分对勃姆石表面的亲和力比锚定部分低。锚定部分优选包含至少两个以[1,1]，[1,2]或[1,3]关系连接的酸基，优选羧酸基，并且与聚合部分连接，优选衍生自来自丙烯酰胺或甲基丙烯酰胺单体单元，优选为硫原子。分散剂可以降低勃姆石分散体的粘度，并且在高剪切应力下，勃姆石分散体的粘度增加和/或形成凝胶或屈服应力材料的趋势。它可以用作例如涂料，陶瓷，油漆，耐火材料，填料或特别是喷墨记录纸或膜中的组分，其中通过其使用保持良好的孔隙率和光泽度。

摘要： The invention relates to a novel kind of anthranilic acid compound that releases a UG as a function of chemical bond cleavage according to Formula (I): Q-(AAS)-UG where UG is an useful group and is chemically bonded to (AAS); (AAS) is an anthranilic acid switching group; and Q is a group in which the bond to (AAS) is broken so that the -(AAS)-UG fragment subsequently decomposes to the free UG. In one embodiment this invention relates to a multilayer silver halide photographic element comprising a support bearing a cyan dye image-forming unit comprised of at least one red-sensitive silver halide emulsion layer having associated therewith at least one cyan dye-forming coupler, a magenta dye image-forming unit comprising at least one green-sensitive silver halide emulsion layer having associated therewith at least one magenta dye-forming coupler, and a yellow dye image-forming unit comprising at least one blue-sensitive silver halide emulsion layer having associated therewith at least one yellow dye-forming coupler, wherein at least one layer additionally contains an anthranilic acid compound according to Formula (II): G-(TG1)q-(AATG)-(TG2)p-PUG where G is a group in which the bond to the timing group is cleaved upon reaction with oxidized developer; TG1 and TG2 represent any known timing or switching group and may be the same or different; q and p are independently 0 or 1; AATG represents an anthranilic acid timing group and PUG is a photographically useful group.
