    • A method for monitoring the coating weight, uniformity, defects or markings present in a coating of a composition applied to a substrate comprises the steps:(a) providing a substrate with a functional coating of a composition comprising an effective amount of uvescer that absorbs radiant energy, i.e., has excitation energy, of wavelength .lambda..sub.1 and emits radiant energy of wavelength .lambda..sub.2 ;(b) scanning the coating with radiant energy having a wavelength within wavelength .lambda..sub.1 ;(c) detecting the radiant energy of wavelength .lambda..sub.2 emitted by the coating; and(d) optionally, correlating the emitted radiant energy to independently measured standard coating weights or thicknesses, of the coating so as to measure coating weight, thickness, uniformity, defects, or markings.The invention also provides novel siloxane polymers containing fluorene uvaphores which are useful in the coating comopsition of the invention.
    • 用于监测施用于基材的组合物的涂层中存在的涂层重量,均匀性,缺陷或标记的方法包括以下步骤:(a)向基底提供包含有效量的吸收辐射的清洁剂的组合物的功能性涂层 能量,即具有波长λ1的激发能,并发射波长λ2的辐射能; (b)用波长λ1的辐射能扫描涂层; (c)检测由涂层发射的波长λ2的辐射能; 和(d)任选地,将所发射的辐射能量与涂层的独立测量的标准涂层重量或厚度相关联,以便测量涂层重量,厚度,均匀性,缺陷或标记。 本发明还提供了可用于本发明的涂料组合的含有芴uvap的新的硅氧烷聚合物。
