    Abstract: The invention provides a method of forming a monolayer of substantive particles including the steps of applying to a substrate a curable composition having substantive particles contained therein, the substantive particles having a particle size on at least one dimension thereof of at least 1 micrometer and being in two or more groups of different sizes; exposing the substantive particle-containing curable composition to a source of energy suitable for effecting polymerization of the curable composition for a sufficient time to effect polymerization of a layer of the curable composition having a thickness of no more than 50% of the height of the largest substantive particles; and optionally, removing uncured curable composition. The invention also provides a method of forming a monolayer of substantive particles in a non-random array where the curable composition comprises a ferrofluid composition. The latter method further comprises the step of subjecting the particle-containing curable ferrofluid composition to a magnetic field for a sufficient time to array the particles in a non-random manner in the composition prior to the exposure.

    Abstract translation: 本发明提供了一种形成单层实质性颗粒的方法,包括以下步骤:将具有其中所含的实质性颗粒的可固化组合物施用于基材,所述实体颗粒的至少一个尺寸的颗粒尺寸至少为1微米, 两组或两组以上不同大小; 将含有实质的含颗粒的可固化组合物暴露于适于实现可固化组合物聚合足够时间的能量源,以实现可固化组合物层的厚度不超过最大厚度的50% 实质粒子 并且任选地,除去未固化的可固化组合物。 本发明还提供了以非随机阵列形成单层实质性颗粒的方法,其中可固化组合物包含铁磁流体组合物。 后一种方法还包括以下步骤:使含有颗粒的可固化铁磁体组合物经历足够的时间以在曝光之前以非随机方式将组合物排列在组合物中。
