Zusammenfassung:	Embodiments of the present disclosure include a polyvinyl ester-based latex having polyvinyl ester-based particles with vinyl ester groups that have been partially hydrolyzed to a predetermined degree, and methods of modifying and forming the polyvinyl ester-based latex of the present disclosure. Embodiments of the present disclosure also include coating compositions that include the polyvinyl ester-based latex of the present disclosure and an optical brightening agent (OBA), where the polyvinyl ester-based particles act as a carrier for the OBA in a coating composition for a print media substrate. Des modes de réalisation de la présente invention concernent un latex à base de polyester de vinyle ayant des particules à base de polyester de vinyle contenant des groupes ester de vinyle qui ont été partiellement hydrolysés jusqu'à un degré prédéterminé, et des procédés pour modifier et former le latex à base de polyester de vinyle selon la présente invention. Des modes de réalisation de la présente invention comprennent également des compositions de revêtement qui comprennent le latex à base de polyester de vinyle selon la présente invention et un agent azurant optique (OBA), les particules à base de polyester de vinyle servant de support à l'OBA dans une composition de revêtement pour substrat de support d'impression.
