Abstract
A process for dyeing and printing hydrophilic fibrous material by the transfer printing process using carriers that are treated with at least one transferable, metallizable dye or color former and optionally a binder that is stable below 230.degree. C, which comprises impregnating the material to be dyed or printed with a solution which contains A. at least one organic solvent with a boiling point higher than 100.degree. C and B. at least one compound that yields complex forming metals, drying the impregnated material and bringing it into contact with the treated carrier, then subjecting both material and carrier to a heat treatment, and subsequently providing the resultant print with an aftertreatment.
