    • A daylight fluorescent pigment based on condensation resins which contain a compound of the formula ##SPC1##In which R.sub.1 is hydroxyalkyl of 1-8 carbon atoms or unsubstituted or substituted phenyl, carboxylic acid amide, cyano, nitro, sulfonic acid amide, alkylsulfone of 1-6 carbon atoms, acetylamino or unsubstituted or substituted benzoylamino or the triazolyl or benzimidazolyl radical, R.sub.2 is a straight-drained or branched alkylene radical of 1-8 carbon atoms which may contain as a bridging member between two alkylene moieties the phenylene or cyclohexylene radical or an oxygen or cycloalkylene and zis 1, 2 or 3. Compared with known pigment dyestuffs of the naphthalic acid imide series they have the advantage that they can be prepared with a dyestuff which is technically obtainable in an easy way. The daylight fluorescent pigments of this invention have a very good fastness to bleeding, a very high tinctorial strength, an improved fluorescence intensity and a very good brilliance. They are advantageously suited for the dyeing of lacquers and varnishes, printing pastes, inks, and plastic materials.
    • 一种基于缩合树脂的日光荧光颜料,其含有下式的化合物:其中R 1为1-8个碳原子的羟基烷基或未取代或取代的苯基,羧酸酰胺,氰基,硝基,磺酰胺,1-6碳烷基砜 原子,乙酰氨基或未取代或取代的苯甲酰氨基或三唑基或苯并咪唑基,R2是1-8个碳原子的直链或支链亚烷基,其可以包含作为亚烷基部分之间的桥连构件,亚苯基或亚环己基或氧 或亚环烷基和Zis 1,2或3.与已知的萘二甲酰亚胺系染料相比,它们具有可以用技术上可以容易地获得的染料来制备的优点。 本发明的日光荧光颜料具有非常好的出血牢度,极高的着色强度,改善的荧光强度和非常好的亮度。 它们有利于染色漆和清漆,印刷浆料,油墨和塑料材料。
