Title: The Innovations of Henry G. Boswell
Introduction
Henry G. Boswell is a notable inventor based in Jacksonville, FL (US). He has made significant contributions to the field of printing inks, holding a total of 5 patents. His work primarily focuses on modified rosin esters, which have applications in gravure printing ink formulations.
Latest Patents
Boswell's latest patents include a binder for use in gravure printing ink formulations. This binder comprises a modified rosin ester resinate prepared by forming a rosin-dienophile adduct. The adduct is then reacted with a polyfunctional hydroxy compound to form an ester, which is further reacted with an acrylic-containing polymer to create a hard rosin ester. The polymer-modified rosin ester resinate is formed by reacting the prepared hard rosin ester with a rosin-dienophile adduct and an acrylic-containing polymer. This process involves reacting the product with reactive zinc, followed by a reaction with lime. The resinate product is dehydrated by refluxing, and its viscosity is adjusted with a hydrocarbon solvent.
