  • Printed test strips to determine glucose concentration in aqueous liquids
    Patent number: 11976317
    Abstract: The present invention provides devices, and a method for preparing the devices, for measuring glucose concentration in a liquid sample. The devices are typically in the form of test strips. The test strips are printed with a reagent varnish comprising glucose oxidase, peroxidase, chromogen, and neutralizer. The chromogen in the reagent varnish changes color when the reagent varnish is exposed to glucose.
    Type: Grant

  • Anion-based aqueous printing inks with improved deinkability
    Patent number: 5932629
    Abstract: An aqueous printing ink composition containing finely dispersed pigments and a synthetic polymer binder, the binder containing: (a) finely dispersed, aqueous-basic insoluble emulsion (co)polymers having a number average molecular weight of from about 10,000 to 1,000,000 and a glass transition temperature of up to 0.degree. C., in intimate admixture with (b) aqueous-basic soluble or dispersible (co) polymers having a number average molecular weight lower than that of the (co)polymers of component (a) and a glass transition temperature of at least 0.degree. C.
