Title: Jerry F. Stone: Innovator in Jet Inks and Waterfast Inks
Introduction
Jerry F. Stone is a notable inventor based in Georgetown, KY (US). He has made significant contributions to the field of ink technology, holding a total of 3 patents. His innovative work focuses on enhancing the performance and reliability of jet inks and waterfast inks.
Latest Patents
One of Jerry's latest patents is titled "Jet inks avoiding solid formation." This invention involves the addition of hydroxyethylated polyethyleneimine to jet ink containing an anionic dye. This addition prevents the formation of whiskers overnight. To address excessive viscosity during start-up, the invention utilizes low molecular weight polyethyleneimine or a low molecular weight hydroxyethylated amine combined with high molecular weight polyethyleneimine.
Another significant patent is for "Waterfast aqueous inks." This waterfast ink formulation includes 3.0% Food Black 2, 2.5% highly hydroxyethylated polyethyleneimine, 10.0% ammonium benzoate, and the remainder being water. The invention operates by facilitating a polar neutralization between the dye and the polyimine upon the loss of water after printing, resulting in a strong affinity of the dye to paper. This technology is applicable to any dye with anionic solubilizing groups that do not contain quaternary ammonium and to any ammonium salt.
