An approach to printing of flat textiles is presented in this work. A screen‐printing method was applied on a cotton fabric. An aqueous printing paste was prepared from thickening and crosslinking agents and an ultraviolet‐sensitive tetrazole ring‐based compound of 2,3,5‐triphenyltetrazolium chloride or nitrotetrazolium blue chloride. After the printing process, a pattern was just visible with the naked eye. The development of colour occurred after exposure of the textile to ultraviolet light of 253.7 nm and was caused by the transformation of 2,3,5‐triphenyltetrazolium chloride or nitrotetrazolium blue chloride salts into the corresponding formazans, which are insoluble in water. The printed designs were resistant to washing. The stability of the colour of the samples is discussed in the case of prolonged irradiation, both with ultraviolet light of 253.7 nm and with daylight. This method of printing is a recent proposition for creative textile designing. It also seems to indicate a likely type of dye that may be further developed as potentially attractive for ultraviolet‐assisted printing or dyeing of textiles.
