Abstract

Dye prepns. contg. at least one dye or optical brightener suitable for transfer printing, with particle size below 15 mu m. Use of dyes less finely milled than the usual 0.01-2 mu m and without usual thickeners, e.g. cellulose derivs., added during milling, allows more universal applicn., by stirring into any type of medium. Prepared printing pastes can be concentrated or modified without affecting their viscosity. Less dye is lost by absorption of fine particles into porous carriers. Pastes with high concns. of dye can be made, and absence of thickeners allows machines for printing the carrier to be run at up to twice usual speeds. The prepns. are esp. suitable for producing dark shades and for use on carpet materials, since they ensure a high applicn. of dye.
