The present invention is directed to water soluble or dispersible polyester compositions, comprising a polyalkylene glycol monoalkyl ether, having mixed nonionic and ionic stabilization prepared in a conventional single step random condensation polymerization. The present invention is also directed to aqueous coating compositions, useful for finishing automobile and truck exteriors, containing a polyester resin with mixed ionic and nonionic stabilization. The coating is especially useful for forming metallic glamour latex based finishes on automobile and truck exteriors that have excellent chip resistance and appearance.
L'invention concerne des compositions de polyester hydrosolubles ou dispersables dans l'eau, qui renferment un polyalkylène glycol monoalkyl éther, à stabilisation mixte ionique/non ionique, élaborées de façon conventionnelle en polymérisation par condensation aléatoire selon une étape. L'invention concerne également des compositions de revêtement aqueuses, utiles pour les finitions d'extérieurs d'automobile et de camion, qui renferment une résine de polyester à stabilisation mixte ionique/non ionique. Le revêtement est particulièrement utile pour des finitions métalliques à base de latex, esthétiques, sur des extérieurs d'automobile et de camion, ayant une excellente résistance à l'arrachage d'éclats et une apparence remarquable.
