  • TITANIUM DIOXIDE-FREE CIGARETTE TIPPING INKS
    Publication number: 20230002973
    Abstract: The present invention provides a method for printing high opacity images or coatings using solvent based inks comprising hollow polymeric microspheres, wherein the inks do not contain titanium dioxide. The International Agency for Research on Cancer (IARC) has classified titanium dioxide as “possibly carcinogenic to humans,” The method of the present invention allows one to avoid the use of inks that rely on titanium oxide for high opacity, which has become of importance for articles that come into contact with one's mouth, for example, cigarette tipping papers.

  • SELF-DISABLING TAMPER-EVIDENT GIFT CARDS
    Publication number: 20220415112
    Abstract: The present invention provides self-disabling tamper evident gift cards, and methods for making and using the gift cards. The gift cards comprise a hidden lower level activation code, and an upper level activation code that is visible. The gift cards incorporate one or more features that render either the lower level or upper level, or both, activation codes unreadable once the lower level activation code is revealed. This prevents card activation at a later time after a first instance when the activation code is accessed.

  • Encapsulated materials with improved properties
    Patent number: 11447640
    Abstract: Described herein are polymer-encapsulated materials and a method for encapsulating materials with polymer via emulsion polymerization. The encapsulated materials include colorants (e.g., pigments and dyes, and in particular fluorescent dyes), optical brighteners, downconverters and upconverters. The encapsulated materials are produced by the emulsion polymerization of ethylenically unsaturated monomers. The polymer-encapsulation method described herein does not require the preparation of a miniemulsion homogenized with special equipment, such as an ultrasonification device, and the resulting polymer-encapsulated materials exhibit optical properties superior to polymer-encapsulated materials prepared by processes that include the preparation of a miniemulsion prepared with such special equipment, such as an ultrasonification device.
