Дневные флуоресцентные пигменты на основе меламинотолуолсульфамидформальдегидного олигомера для эмалевых красок

Abstract

The article considers the availability of daylight fluorescent pigments based on melaminetoluolsulfamideformaldehyde oligomer with the use of certain derivatives of 4-dialkilaminonaphthalimides. For this purpose we used derivatives which form chemical bonds with the polymer matrix. This approach provides the possibility of obtaining new chemical structures with increased light fastness, brightness, purity of color, and also increases migratory resistance of certain polymers in bulk during coloration (e.g., polyethylene, polypropylene, etc.). Colorimetric characteristics of enamel paints by means of obtained pigments were defined.
