Abstract

Invnetia se refera la un procedeu de obtinere a unor solutii de coloranti metal-complecsi ai unor compusi azoici fara grupe sulfonice, stabile la stocare si în conditiile de vopsire a pieilor naturale prin procedeul de acoperire, procedeul constând în adaugarea la solutiile de coloranti metal-complecsi la 60 grade C, a polivinilpirolidonei K = 30, urmata de încalzire la 70 ... 80 grade C, mentinere timp de 2 ... 3 h la aceasta temperatura si apoi racire la temperatura camerei.
