The optically variable pigments were produced by wet chemical method, and Ti coated mica having interference colors acted as host materials.
采用具有干涉色的云母钛作为基质材料,通过湿化学法制备随角异色功能颜料。
The UV absorb capability of 5%Nd_2O_3/TiO_2/Mica is higher than that of mica titanium, and UV shielding characteristic works well with the best pearl effect of green-mauve optically variable.
而且具有绿-淡紫随角异色效应。
Optically variable pigment has preferable color travel effect and higher chroma, they can be widely used in cosmetics, plastics, oil paint and other decorate product.
随角异色颜料由于具有较强的变色效果和高的色度,在化妆品、塑料、涂料等装饰领域的应用受到人们的青睐。
In this paper, Claisen condensation of isochroman?4?one as starting material with diethyl oxalate is carried out to form β?diketone compound of isochroman?4?one.
以异色满酮 4为起始原料 ,经Claisen缩合得其 β 二酮衍生物 ,再与水合肼进行Knorr反应环合成 3 乙氧甲酰基和 3 肼甲酰基异色满并吡唑衍生物 ,通过酰肼与糠醛反应成腙后 ,分别与巯基乙酸和氯乙酰氯反应合成了标题化合物 。
