Abstract
Official abstract text for this publication.
A coating composition comprising a polyglycidyl ether of a 2,2′-biphenol that is substantially free of bisphenol A, bisphenol F and their derivatives and residues is disclosed. Food packages coated at least in part with such coatings are also disclosed.
First claim
Opening claim text (preview).
The invention claimed is: 1. A food or beverage container containing a coating contacting the food or beverage in which the coating is the cured reaction product of a chain-extended polyglycidyl ether of 2,2′-biphenol, wherein the coating is substantially free of bisphenol A and/or derivatives and/or residues thereof and bisphenol F and/or derivatives and/or residues thereof. 2. The food or beverage container of claim 1 in which the polyglycidyl ether of 2,2′-biphenol is further chain extended with a polyol. 3. The food or beverage container of claim 2 in which the polyol is a dihydric phenol. 4. The food or beverage container of claim 3 in which the dihydric phenol is 2,2′-biphenol. 5. The food or beverage container of claim 1 in which the 2,2′-biphenol is of the structure: in which R 1 , R 2 , R 3 , R 4 , R 5 , R 6 , R 7 and R 8 may be the same or different and are independently hydrogen and hydrocarbyl. 6. The food or beverage container of claim 1 in which the polyglycidyl ether of 2,2′-biphenol is phosphated. 7. The food or beverage container of claim 1 , which is a metal can. 8. The food or beverage container of claim 6 , which is a metal can.
