Improvements introduced in the object of the main patent no. 184,681, granted on november 19, 1948, by the process of making pigments that have fluorescent properties by which the organic substance containing nitrogen in the form of -nh 2, = nh, or n, to which the main patent refers, is not a single one but the mixture of two or more groups -nh2, = nh or n (1 mol) and the other one only of these groups (1 mol); these two substances are dissolved in a medium ph, 7-9, by an aldehyde (3 moles) in aqueous solution, adding 0.25 to 5% on the whole of a dye of those mentioned in the main patent, heating the whole (60 to 120 degrees centigrade) for about 48 hours, after which, after cooling the resulting solid mass, it is pulverized to the desired degree of fineness.
