Water-fastness of inks containing pigment and a polymeric dispersant is improved by the addition of core-shell or tetrafluoroethylene emulsion polymers. The printed ink images exhibit improved resistance to smudge or smear when handled or marked with highlight pens.
A new efficient and convenient synthetic process of perfluorinated vinylethers containing an ester group was developed by pyrolysis in the presence of α-trifluoromethyl moiety without loss of –COF functional group followed by alcoholysis in high yield.
