SU655333A3 - Method of pigmenting high-molecular organic material - Google Patents

Description

N-methylpyrrolidone before boiling. After re-isolation and drying, 2.8% v / v are obtained. including pigment in the form of a light red soft powder. Pigment paints polyvinyl chloride in a very intense yellow-red hue with excellent strength to light and migration.

Examples 2-5. In example 1, get the pigments presented in table. one.

Example s 24-35. In tab. 3 shows other high-molecular-weight organic materials that can be pigmented by the pigments according to the proposed method with obtaining light-resistant and migration-resistant dyeing.

Claims (1)

Invention Formula The method of pigmenting high molecular weight organic material using a monoazo pigment is different from R1 to chlorine, methyl, hydroxymethyl, hydroxy to R2 or hydrogen or phenyl; X is amino or CH20; Y - oxygen, sulfur or imino group Table 3 In order to improve the light fastness of the color, a compound of the general formula 10 is oxygen or an imino group as a monoazo pigment.
