Zusammenfassung:	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.
