摘要:
The present invention provides aqueous dispersions that, for example, include the reaction product of an oxirane-functional vinyl addition polymer having an oxirane functionality between 0.5 and 5; an acid-functional polymer having an acid number 30 to 500; and a tertiary amine. Also described are coating compositions containing the dispersion and methods of forming the dispersion.
摘要:
The present application relates to films and packaging articles having films bonded thereto. Also provided are methods of making and applying multilayered films. Exemplary polymeric films include a first layer adjacent the metal sheet having one or more polyester materials and a plurality of metal flakes disposed therein, and a second layer having a majority by weight of one or more crystallizable polyester-based polymers. Other exemplary films include a first layer adjacent the metal sheet having one or more amorphous polyester materials, and a second layer having a majority by weight of one or more crystallizable polyester-based polymers and an opacifying amount of titanium dioxide filler. Yet other exemplary films comprise an oxygen-scavenging material and include a first layer adjacent the metal sheet having one or more amorphous polyester materials, and a second layer having a majority by weight of one or more crystallizable polyester-based polymers.
