A light-attenuating composition and method of using it are described. The light-attenuating composition may be selectively applied to a radiant energy sensitive material on the substrate. Actinic radiation applied to the composite chemically changes portions of the radiant energy sensitive material not covered by the light-attenuating composition. The light-attenuating composition attenuates light in at least the UV range and is water-soluble or water-dispersible.
本文描述了一种光衰减组合物及其使用方法。光衰减组合物可有选择地应用于基底上的辐射能敏感材料。施加到复合材料上的阳极辐射会使未被光衰减组合物覆盖的辐射能敏感材料部分发生
化学变化。光衰减组合物至少能衰减紫外线范围内的光,并且是
水溶性或
水分散性的。
