But then I happened to read that lead in paint makes colors (particularly yellow and red) brighter and last longer; because lead costs less than alternates, cheaper toys are more likely to contain it.
可后来我偶然学到了一点知识：涂料中所含的铅有让色彩更艳丽、使油漆更耐用的作用，特别是红色及黄色涂料；而由于含铅涂料要比其他代用涂料便宜，因此，便宜的玩具含铅的可能性更高。
Some polyurethane resin coating contains more free TDI, brushed in besmear in the process of volatile, will lead to latex paint of yellow.
有的聚氨酯树脂涂料中含较多的游离tdi，在涂刷挥发过程中，将会导致乳胶涂料泛黄。
