  An aqueous coating fluid is described comprising gelatin at a concentration of at least 1 wt% and a colloidal particle dispersed material phase at a volume fraction of at least 0.01, wherein at least 20% of the gelatin comprises a gelatin prepared from hydrolysis of ossein using sodium or potassium hydroxide. The present invention enables increasing the concentrations of a coating fluid containing gelatin and dispersed sub-micron colloidal materials, reducing the size of the sub-micron colloidal materials in such a coating fluid, and/or including higher molecular weight gelatin in such a coating fluid without detrimentally increasing the viscosity of such fluids. The invention further enables reducing the viscosity of an aqueous coating fluid containing gelatin and dispersed insoluble colloidal material, without needing to reduce the concentration of gelatin or colloidal materials, increase the size of the sub-micron colloidal materials, and/or reduce the molecular weight of the gelatin. Each such advantage may be achieved either individually, or in combinations to varying extents, without the need to fundamentally change the composition of the materials in the coating fluid.

  本发明描述了一种水性涂布液，该涂布液包含浓度至少为 1 wt%的明胶和体积分数至少为 0.01 的胶体颗粒分散材料相，其中至少 20% 的明胶由使用氢氧化钠或氢氧化钾水解骨素制备的明胶组成。本发明能够提高含有明胶和分散亚微米胶体材料的涂布液的浓度，减小亚微米胶体材料在涂布液中的尺寸，和/或在涂布液中加入更高分子量的明胶，而不会不利地增加涂布液的粘度。本发明还能进一步降低含有明胶和分散的不溶胶体材料的水性包衣液的粘度，而无需降低明胶或胶体材料的浓度、增大亚微米胶体材料的尺寸和/或降低明胶的分子量。这些优点可以单独实现，也可以不同程度地组合实现，而无需从根本上改变包衣液中材料的组成。

  An aqueous coating fluid is described comprising gelatin at a concentration of at least 1 wt% and gelatin hardener at a level from 1-200 effective µmole hardener per gram of coating fluid, wherein at least 20% of the gelatin comprises a gelatin prepared from hydrolysis of ossein using sodium or potassium hydroxide. Relative improvements are obtained in reducing the rate of chemical gelation of a coating fluid containing gelatin and a hardener, without the need for chemically modifying functional groups of the gelatin. The invention further enables an increase in coating fluid concentration, increase in the fluid viscosity, reduction in the ratio of added anionic polymer to gelatin, and/or increase in the pH of a coating fluid containing gelatin and a hardener, without detrimentally increasing the rate of chemical gelation of the coating fluid. The invention also enables the inclusion of relatively more reactive hardeners in a coating fluid containing gelatin, and/or the inclusion of relatively higher molecular weight gelatin in a coating fluid containing hardener, without detrimentally increasing the rate of chemical gelation of the coating fluid. Each such advantage may be achieved either individually, or in combinations to varying extents.

  描述了一种水性涂布液，包含浓度至少为 1 wt%的明胶和每克涂布液 1-200 有效微摩尔硬化剂水平的明胶硬化剂，其中至少 20% 的明胶包含使用氢氧化钠或氢氧化钾水解骨化皂制备的明胶。本发明在降低含有明胶和硬化剂的涂布液的化学凝胶速率方面取得了相对的改进，而无需对明胶的官能团进行化学修饰。本发明进一步提高了涂布液的浓度，增加了涂布液的粘度，降低了添加的阴离子聚合物与明胶的比例，和/或提高了含有明胶和固化剂的涂布液的 pH 值，而不会不利地增加涂布液的化学凝胶速率。本发明还可以在含有明胶的涂布液中加入反应性较强的固化剂，和/或在含有固化剂的涂布液中加入分子量较高的明胶，而不会不利地增加涂布液的化学凝胶速率。这些优点可以单独实现，也可以不同程度地组合使用。
