TL;DR: In this paper, a semi-solid, thixotropic hectograph printing ink containing non-drying semi solid oleaginous material, film-forming binder material at least partially dissolved in a relatively high boiling organic solvent having dispersed therein hectograph dyestuff and finely-divided fusible, waxy particles, printing the hectograph composition in image form onto a master sheet or as a continuous or spot layer on a foundation.
Abstract: Novel thixotropic hectograph printing ink and process for printing hectograph master sheets or transfer sheets therewith comprising preparing a semi-solid, thixotropic hectograph printing ink containing non-drying semi-solid oleaginous material, film-forming binder material at least partially dissolved in a relatively high boiling organic solvent having dispersed therein hectograph dyestuff and finely-divided fusible, waxy particles, printing the hectograph composition in image form onto a master sheet or as a continuous or spot layer on a foundation and heating such as by means of infrared radiation to heat the composition to a temperature above the melting point of the waxy particles to fuse the composition and render it smooth, smear-resistant and stable
