    Abstract

    Reliable, discriminating spot tests can be important in rapidly determining differences involving paint sample comparisons. Reagents offering high color intensity with a broadranged spectrum obviously produce the best basis for sample analysis. The Le Rosen reaction [1, pp. 137–140] is such a test, offering definitive discrimination of many aromatic compounds. Application of this test to small paint samples offers a clearer differentiation than sulfuric acid [2] and a wider applicability than diphenylamine-type reagents, both accepted color-solubility tests for paint classifications.
