ABSTRACT:
Solvent hectograph compositions which are resistant to rapid thickening and gelling during storage in the presence of ambient humidity comprising a cellulose ether film-forming binder material, at least one oleaginous material which is substantially incompatible with said binder material and a major amount by weight of particulate spirit-soluble solid hectograph imaging material, the volatile solvent for said binder material being a lower aliphatic ester which is a substantial non-solvent for said imaging material and which has a partial miscibility with water, the process of making such compositions and the process of producing pressure-sensitive transfer elements from said compositions.
