    • A foamed, opacifying element having a target light blocking value (LBVT) and a target porous substrate is prepared by determining the light blocking value (LBVs) of the target porous substrate; calculating the LBVT-S difference; choosing a foamable aqueous composition; determining a dry coating weight for the chosen foamable aqueous composition (when foamed); and using the dry coating weight to form the single dry opacifying layer as the only layer disposed on the target porous substrate, such that the single dry opacifying layer has light blocking value that is equal to LBVT-S, ± 10%. The chosen foamable aqueous composition comprises the essential components (a) through (e) described herein. The desired foamable aqueous composition can be chosen from a set of similar compositions to achieve the desired LBVT with the noted target porous substrate using suitable mathematical formula relating dry coating weight to light blocking value and a suitable data processor.
    • 通过确定目标多孔基材的光阻值(LBVs)制备具有目标遮光值(LBVT)和目标多孔基材的发泡不透明元件; 计算LBVT-S差值; 选择可发泡的含水组合物; 确定所选可发泡含水组合物(当发泡时)的干涂层重量; 并且使用干涂层重量形成作为设置在目标多孔基材上的唯一层的单干透明层,使得单干透明层具有等于LBVT-S的光阻值, 10%。 所选的可发泡含水组合物包含本文所述的基本组分(a)至(e)。 可以从一组相似的组合物中选择所需的可发泡含水组合物,以使用关于干涂覆重量与遮光值有关的合适数学公式和合适的数据处理器来实现具有所述目标多孔基底的期望的LBVT。
