Developments in printing ink formulations: A new series of polyfunctionally substituted pyridine azo‐ and hydrazono derivatives for screen printing of textiles
Abstract
A new series of polyfunctionally substituted pyridine azo‐ and hydrazono dyes suitable for screen printing of polyester, cotton and polyester/cotton blend fibres have been synthesised. The prints are characterised by high depth of colour and good fastness to light and wet processings. Proofs of structure of the synthesised compounds based on microanalytical and spectroscopic data are given and discussed. The effect of substituents on the electronic absorption spectra and on the dye/fibre binding mechanism has been studied.
