摘要

A Fluorescent Yellow AZO Pigment exhibits a Spectral response to incident Radiation, in which the maximum Response between ounty 520 560 nanometers and Lengths.Exceeds the response to 600 nanometers. The fluorescenteam aril pligmento AZO Crystallite size has increased.Other Objects of the invention are printing inks, Plastic Coatings and compositions containing Said Pigment.A process for the preparation depigmentos azo fluorescenteamaril comprises: (a) Prepare a solution of tetrazo 3,3 dichlorobenzidine by adding 33 diclorobenzidina to u00e1cidoclorhu00eddrico and Sodium nitrite; (b) preparing a suspension of a Coupler coupling Dissolving in a solution of sodium dehidroxido,And forming unprecipitado suspended Suspension Coupling with acetic acid; (c) reacting the solution tetrazo 33 elprecipitado dichlorobenzidine with suspended to form a Pigment intermediary; (d) filter that termediario Wash with water; (e) the intermediary; (f) Dry dichointermediario; (g) TrainingA Slurry of the intermediary in a Solvent; and (H) the intermediary heat in Slurry, Said calentamientoopcionalmenterealizado under P resion.Other Objects of the invention are an improved method for the manufacture of Thermoplastic materials or Packing tape; an improved poliolefu00ednico Thermoplastic material and an article of manufactureImproved ion tool in the process of packaging.
