Abstract
Abstract A jet printing ink composition comprises 2 to 60 wt.% of a binder precursor of an alkoxysilane having the formula R4-nSi(OH)n (n=0 to 2; and R represents a C1-C4 alkoxy group, methoxyethoxy, ethoxyethoxy or phenoxy group) or an oligomer thereof; and 25 to 95 wt.% of a solvent for said alkoxysilane or oligomer thereof; 0.001 to 5 wt.% of a solvent soluble acid; and 0.1 to 8 wt.% of a solvent soluble dyestuff, if necessary, further comprises up to 2 wt.% of a solvent soluble inert silicone oil for inhibiting blotting and up to 3 wt.% of an electroconductive agent.
