摘要

"Dyeing or printing materials made of natural and synthetic fibres polu00ecmeros hydrophobic.The present invention relates to a process for the dyeing or printing of materials made from natural polymers and synthetic hydrophobic fibers.Characterized in that it comprises the use of dyes of the formula in which R ~ 1 ~, is hydrogen, hydroxyl or a radical - nhco - R ~ 6 ~,In which R is C ~ 1 ~ 6 ~ ~ C ~ 6 ~ alkyl or not replaced or fenila replaced with C ~ 1 ~ C ~ 4 ~ alkyl or halogen, R ~ 2 ~ is hydrogen, hydroxyl or a radical W - R ~ 7 ~,In which w is nhco - or - S - and R ~ 7 ~ is C ~ 1 ~ C ~ 6 ~ alkyl or not replaced or fenila replaced with C ~ 1 ~ C ~ 4 ~ alkyl or halogen, R ~ 3 ~ is hydrogen.R ~ 4 ~ is hydrogen or hydroxyl; R ~ 5 ~ is hydrogen, halogen, metu00f3xi, fenu00f3xi or feniltio,Or R ~ 3 ~ R ~ 4 ~ combine to the formation of the radical of the formula in which the rings a and B may be independently contain other substituents.For the use of such dyes for the dyeing of materials manufactured's trichrome natural polymer or synthetic fibres and the hydrophobic dye in mass of plastic materials and the prod.Uu00e7u00e3o combinations solid plastic material of tone on tone and material of natural polymer or synthetic fiber material.
