    • In one embodiment the present invention includes a computer-implemented for determining whether or not a data object is frozen. The method comprises accessing, by a user on a computer, a first data object of a plurality of data objects in one or more computer software applications. The plurality of data objects are assigned to a plurality of entities, where each entity specifies a category, and each of the plurality of data objects belong to a specific entity. The method determines if the first data object is frozen based on a relationship between the first entity and a second entity.
    • 在一个实施例中,本发明包括用于确定数据对象是否被冻结的计算机实现。 该方法包括由计算机上的用户访问一个或多个计算机软件应用中的多个数据对象的第一数据对象。 多个数据对象被分配给多个实体,其中每个实体指定类别,并且多个数据对象中的每一个属于特定实体。 该方法基于第一实体和第二实体之间的关系确定第一数据对象是否被冻结。

    • This invention refers to a novel process for the synthesis of polyethylene imine (PEI)-based pigment dispersants characterized by a “grafting from” approach, allowing the manufacture of solvent based dispersant systems. The polyethylene imine (PEI)-based pigment dispersant can be presented by the formula (I) X-(T)m-P-(T)n-H wherein P is a polyethyleneimine (PEI) back-bone; T is a residue —CO-A-O— wherein A is C2-C12 alkylene optionally substituted with C1-C6 alkyl with the proviso that each linkage between P and T is an amide bond and each linkage between X and T is an ester bond, X is a modifier or terminator residue R—CO— wherein R is a linear or branched, saturated or unsaturated alkanecarboxylic acids having from 1 to 22 carbon atoms or an unsaturated fatty acid residue or a hydroxycarboxylic residue or a polyester residue obtained from polycondensation of hydroxycarboxylic acids, or an acid terminated polyether; n, m independently are a number from 1 to 100.
    • 本发明涉及一种用于合成以“接枝”方式为特征的聚乙烯亚胺(PEI)的颜料分散剂的新方法,允许制造基于溶剂的分散剂体系。 基于聚乙烯亚胺(PEI)的颜料分散剂可以由式(I)X-(T)m-P-(T)n-H表示,其中P是聚乙烯亚胺(PEI)背骨; T是残基-CO-AO-,其中A是任选被C 1 -C 6烷基取代的C 2 -C 12亚烷基,条件是P和T之间的每个连接是酰胺键,X和T之间的每个连接是酯键,X 是改性剂或终止剂残基R-CO-,其中R是具有1至22个碳原子的直链或支链饱和或不饱和烷烃羧酸或不饱和脂肪酸残基或羟基羧酸残基或由羟基羧酸缩聚获得的聚酯残基 ,或酸封端的聚醚; n,m独立地为1至100的数。
