Abstract
Abstract Textile materials containing cellulose and synthetic fibers can be colored by impregnating or printing them with an aqueous composition containing an organic colorant, a surface-active agent, a carrier of limited water-solubility, an organic solvent and a thickener and completing the coloration procedure in usual manner. If the organic solvent is water-soluble then no carrier is necessary.

Claims Analysis
Total Claims: 19
Claim 1
Independent Claim
86 words
In a process for the coloration of a textile material containing cellulose and synthetic fibers in an aqueous organic medium the improvement comprising impregnating or printing said material with an aqueous composition consisting essentially of a pigment, a disperse dyestuff or a mixture of a pigment and a disperse dyestuff a surface-active agent, a carrier of limited water-solubility, an organic solvent and a thickening agent, said composition containing per kilogram of printing paste or liter of padding liquor 30 to 200 g of surface active agent.
Claim 2
Dependent Claim
86 words
In a process for the coloration of a textile material containing cellulose and synthetic fibers in an aqueous organic medium the improvement comprising impregnating or printing said material with an aqueous composition consisting essentially of a pigment, a disperse dyestuff or a mixture of a pigment and a disperse dyestuff a surface-active agent, a carrier of limited water-solubility, an organic solvent and a thickening agent, said composition containing per kilogram of printing paste or liter of padding liquor 30 to 200 g of surface active agent.
Claim 3
Dependent Claim
