INK AND COATING COMPOSITIONS FOR PACKAGING APPLICATIONS INCLUDING FUNCTIONALIZED HOMOPOLYMERS OR COPOLYMERS OF VINYL ALCOHOLS

摘要

The present invention describes an ink or coating composition comprising a functionalized homopolymer or copolymer of vinyl alcohol according to the formula: P-(R)n. P includes a straight or branched chain polymer backbone comprising a homopolymer or copolymer of vinyl alcohol, a monomer, and a reactive coupling group comprising a ketone- or ketoester-containing functional group. R includes an aminosilane- and/or aminosilanol-containing side chain attached to the polymer backbone via the reactive coupling group. There also is described a laminated package including the ink or coating composition. Further there is described a functionalized homopolymer or copolymer of vinyl alcohol used in inks and coatings.
