LOW VOC, WATER-BASED COATING COMPOSITIONS SUITABLE FOR PROTECTING METAL CONTAINING SUBSTRATES INCLUDING FOOD AND BEVERAGE PACKAGES

摘要

The present invention provides coating compositions and methods of using these compositions to form tough, abrasion resistant, and water resistant coatings on metal-containing substrates. Coating compositions of the present invention are preferably derived from one or more ingredients comprising at least one copolymer, referred to herein as Copolymer I, that preferably comprises (a) one or more repeating units (Repeating Unites) A) comprising at least one hydrophilic ester functionality and at least one polar functionality; and (b) one or more additional kinds of copolymerizable repeating units (Repeating Unites) B).
