The resistance of three silicone and one polyvinyl chloride maxillofacial materials to staining by tea, lipstick, and disclosing solution was measured by reflectance spectrophotometry. Changes in color caused by staining were larger than changes caused by color instability of the base elastomers or pigments under conditions of accelerated aging.
通过反射分光光度法测量了三种硅酮材料和一种聚氯乙烯颌面材料对茶、口红和显示液染色的抗性。在加速老化条件下，染色引起的颜色变化大于基础弹性体或颜料的颜色不稳定性引起的变化。
