    Abstract: Coating formulations capable of forming coatings exhibiting minimal or no blushing may comprise an aqueous carrier fluid, an amine-terminated polyamide, a resin, an acid catalyst, and a water-soluble fluorescent compound. The resin may comprise at least one compound selected from the group consisting of an aminoplast melamine-based resin, a benzoguanamine-based resin, a cresolformaldehyde-based resin, and any combination thereof. Such coating formulations may be curable in at least about 1 minute at 200° F. Coatings formed therefrom may comprise a crosslinked reaction product of the amine-terminated polyamide and the resin. The water-soluble fluorescent compound may be compliant with 21 CFR § 175.300 (2019), of which quinine is a representative example. Such coatings that are compliant with 21 CFR § 175.300 may be disposed upon a surface in contact with a foodstuff, such as upon at least a portion of an easy-open end of a can or similar container.

  • Publication number: 20230257628
    Abstract: Surfactants are commonly employed to prepare aqueous polymer emulsions (latex emulsions) used for forming polymer coatings. Migration of surfactants following polymer coating deposition can be problematic, and poor surface adhesion may occur in some cases. Polymer emulsions leading to improved surface adhesion and other advantageous properties may comprise: an aqueous fluid, a plurality of core particles, a polymer layer formed around at least a majority of the plurality of core particles, and one or more surfactants. The polymer layer comprises a polymer formed from one or more ethylenically unsaturated monomers. The one or more surfactants comprise at least one reactive surfactant having an ethylenic unsaturation that is covalently incorporated within the polymer. The at least one reactive surfactant is absent from the core particles when the polymer layer is formed thereon. The polymer layer is substantially uniform in composition.

  • Publication number: 20220033674
    Abstract: Electrophotographic printing techniques offer excellent image quality, but image adhesion to a desired substrate may be problematic in many instances. Primer coatings for improving image adhesion to a substrate may be formed from primer compositions comprising a fluid and an amine-functionalized copolymer dispersed in the fluid as an emulsion, in which the amine-functionalized copolymer has an amine number of about 10 to about 180 mg KOH/g copolymer. The fluid may be aqueous or organic. Suitable amine-functionalized copolymers may be formed by an emulsion polymerization reaction of one or more first ethylenically unsaturated monomers lacking an amine group and one or more second ethylenically unsaturated monomers bearing at least one amine group. The at least one amine group comprises a side chain of the amine-functionalized copolymer.

  • Publication number: 20220025196
    Abstract: Aqueous primer compositions suitable for electrophotographic printing and inkjet printing are frequently incompatible with one another, such that coated substrates for each printing technique need to be stockpiled separately. Aqueous primer compositions containing components to facilitate both electrophotographic printing and inkjet printing and that remain compatible with each other may comprise a polyvalent metal salt dispersed in an aqueous fluid, and an amine-functionalized copolymer dispersed as an emulsion in the aqueous fluid, in which the amine-functionalized copolymer has an amine number of about 10 to about 180 mg KOH/g copolymer and a glass transition temperature of about 0° C. to about 50° C. Suitable amine-functionalized copolymers may be formed by an emulsion polymerization reaction of one or more first ethylenically unsaturated monomers lacking an amine group and one or more second ethylenically unsaturated monomers bearing at least one amine group.
