Summary:Process for the continuous dyeing of a textile material web made of polyamide fibers using an 1:2 metal complex dyestuff, by padding the dyestuff together with a thermally crosslinkable bindersystem on the basis of a combination of acrylic acid derivatives with a highly etherified precondensation product of melamine and formaldehyde, a crosslinkable protective colloid in the presence of a catalyst or an acid-yielding agent that give an acid effect only under heat, from an aqueous liquor under weakly alkaline conditions, and fixing it on the material by means of dry heat.
