Abstract
Abstract A process of dyeing or printing of synthetic fiber materials by means of disperse dyes carried out in the presence of at least one derivative of a metal having an atomic number in the range of 24 through 30 to prevent or diminish the degradation of the dye during the dyeing or printing process, and ready-to-use colorant compositions for this process.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
74 words
A process for dyeing materials containing synthetic fibers by means of disperse dyes which comprises carrying out the dyeing by the exhaustion method in the presence of at least one metallic salt of an inorganic or organic acid, the metal having an atomic number in the range of 24 through 30, said metallic salt being added in an amount of 0.2 to 2% by weight expressed as metal in relation to the disperse dye.
Claim 2
Dependent Claim
74 words
A process for dyeing materials containing synthetic fibers by means of disperse dyes which comprises carrying out the dyeing by the exhaustion method in the presence of at least one metallic salt of an inorganic or organic acid, the metal having an atomic number in the range of 24 through 30, said metallic salt being added in an amount of 0.2 to 2% by weight expressed as metal in relation to the disperse dye.
Claim 3
Dependent Claim
22 words
The process according to claim 1 wherein the metallic salt is an inorganic or organic salt of nickel, cobalt, zinc or manganese.
Claim 4
Dependent Claim
27 words
A process according to claim 1 wherein the metallic salt is a chloride, sulfate, nitrate, phosphate, formate, acetate or oxalate or a salt of an anionic dispersant.
Claim 5
Dependent Claim
