  • Printing ink and coating compositions containing starch
    Patent number: 9382659
    Abstract: An aqueous printing ink and coating composition contains colorant, one or more high molecular weight starches and one or more water soluble acrylic polymers or co-polymers.
    Type: Grant
    Filed: December 2, 2005
    Date of Patent: July 5, 2016
    Assignee: Sun Chemical Corporation

  • SUBSTRATE PRINTED WITH A WATER-BASED URETHANE PRINTING INK WITH IMPROVED PERFORMANCE PROPERTIES
    Publication number: 20130337185
    Abstract: A substrate has a surface printed with an ink or coating composition with excellent adhesion and dry rub resistance, and very good oil and saline rub resistance (crock) properties using a multi-functional carbodiimide as a crosslinker for nonwoven substrates. The rub performance of the ink or coating printed on a nonwoven substrate has been found to be superior to that of a first Sun benchmark ink including pigments for four color printing. In another embodiment, a carbodiimide crosslinker such as multifunctional Carbodilite SV-02 is added to the compositions to further improve rub resistance (crock) and retain liquid characteristics post inoculation when compared to compositions using aziridine as a crosslinker. In a further embodiment, a thin polyolefin film exemplifying a backsheet of a hygiene product was printed with the same crosslinked ink or coating composition and compared with a second Sun benchmark set of inks.
