白色颜料黄度分子式:CAS号:性质:指白色颜料的白度偏离特定的白色而向黄色调发展的程度,可用黄度指数(yellowness index;yellow factor)表示。其值YI=100(R-B)/G(R,B,G分别为红色光、蓝色光及绿色光的反射度,可作为三刺激色度计的读数)。利用国际照明委员会(CIE)三刺激值,上式可变为YI=(128X-106Z)/y。美国涂料协会规定的泛黄视觉等级为10级制,其中10级表示无泛黄,2级表示泛黄严重,1级表示已经由黄变棕。在许多情况下,希望白色颜料的黄度最小,甚至不带黄度,略带蓝相,即CIE Lab值中的6值为负值,L值(明度)要高。这对白色颜料的粒度及粒度分布以及杂质含量等提出了更高的要求。
