ANTIMICROBIAL COMPOSITES, FILMS, LABELSTOCKS AND LABELS

This invention relates to antimicrobial composites, films, labelstocks and labels. The antimicrobial composites comprise a mixture of (A) a terpolymer prepared from a mixture comprising (i) an olefin, (ii) at least one copolymerizable comonomer comprising ethylenically unsaturated organic acids or esters, vinyl esters of saturated carboxylic acids and mixtures of two or more thereof, and (iii) carbon monoxide, and (B) an antimicrobial composition which comprises at least one metal chlorite and at least one hydrophilic material capable of reacting with the metal chlorite when exposed to water. The composites which are described herein are useful in preparing films, labelstocks and labels which exhibit the desirable antimicrobial properties by providing a controlled release of chlorine dioxide gas over an extended period of time. La presente invencion se refiere a compuestos antimicrobianos, peliculas, portamarcadores y marcadores. Los compuestos antimicrobianos comprenden una mezcla de (A) un terpolimero preparado a partir de una mezcla que comprende (i) una olefina, (ii) por lo menos un comonomero copolimerizable que comprende esteres o acidos organicos etilenicamente insaturados, vinilesteres de acidos carboxilicos saturados y mezclas de dos o mas de estos, y (iii) monoxido de carbono, y (B) una composicion antimicrobiana que comprende al menos un clorito metalico y al menos un material hidrofilico capaz de reaccionar con el clorito metalico al exponerse al agua. Los compuestos que aqui se describen son utiles para preparar peliculas, portamarcadores y marcadores que exhiben las propiedades antimicrobianas deseables al proporcionar una liberacion controlada de gas de dioxido de cloro durante un periodo extendido de tiempo.
