Process for printing synthetic, hydrophobic fibrous material according to the transfer printing principle

摘要

Process for printing synthetic, hydrophobic fibre material or blends of synthetic, hydrophobic fibre material with prepared cellulose materials or prepared cellulose materials by the transfer printing method with sublimable azo dyes of the formula II IMAGE where R1 is H, straight-chain or branched alkyl of 1 to 4 carbon atoms or straight-chain or branched alkenyl of 3 to 4 carbon atoms, R2 is straight-chain alkyl of 1 to 4 carbon atoms or straight-chain alkenyl of 3 to 4 carbon atoms.
