Abstract:
(EN) Provided are a polyester resin and a paint resin composition containing the same, which have very high curability and are capable of forming a paint film with excellent workability, retort resistance, content resistance and dent resistance. This polyester resin comprises a polycarboxylic acid component and a polyol component, and has the following conditions (i) to (iii): (i) the sum of the copolymerization ratio of a terephthalic acid component and a 2,6-naphthalenedicarboxylic acid component of the polycarboxylic acid component that constitutes the polyester resin is 80 mol% or more; (ii) the copolymerization ratio of the 2,6-naphthalenedicarboxylic acid component of the polycarboxylic acid component that constitutes the polyester resin is 2 to 80 mol%; and (iii) the sum of the copolymerization ratio of an ethylene glycol component and a 1,2-propylene glycol component of the polyol component that constitutes the polyester resin is 50 mol% or more, the 1,2-propylene glycol component being included in a greater amount than the ethylene glycol component.
(FR) L'invention concerne une résine de polyester et une composition de résine de peinture contenant celle-ci, qui ont une aptitude au durcissement très élevée et sont aptes à former un film de peinture ayant d'excellentes aptitude à la mise en oeuvre, résistance au passage en autoclave, résistance au contenu et résistance aux bosses. Cette résine de polyester comprend un composant acide polycarboxylique et un composant polyol, et a les conditions (i) à (iii) suivantes : (i) la somme du rapport de copolymérisation d'un composant acide téréphtalique et d'un composant acide 2,6-naphtalènedicarboxylique du composant acide polycarboxylique qui constitue la résine de polyester est de 80 % en moles ou plus ; (ii) le rapport de copolymérisation du composant acide 2,6-naphtalènedicarboxylique du composant acide polycarboxylique qui constitue la résine de polyester est de 2 à 80 % en moles ; et (iii) la somme du rapport de copolymérisation d'un composant éthylène glycol et d'un composant 1,2-propylène glycol du composant polyol qui constitue la résine de polyester est de 50 % en moles ou plus, le composant 1,2-propylène glycol étant compris dans une quantité supérieure à celle du composant éthylène glycol.
(JA)  非常に高い硬化性を持ち、なおかつ加工性も優れ、耐レトルト性、耐内容物性および耐デント性にも優れる塗膜を形成することのできるポリエステル樹脂、およびこれを含有する塗料用樹脂組成物を提供する。 ポリカルボン酸成分とポリオール成分からなり、次の(i)~(iii)の条件を有するポリエステル樹脂。(i)ポリエステル樹脂を構成するポリカルボン酸成分のうち、テレフタル酸成分と2,6-ナフタレンジカルボン酸成分の共重合比率の合計が80モル%以上である、(ii)ポリエステル樹脂を構成するポリカルボン酸成分のうち、2,6-ナフタレンジカルボン酸成分の共重合比率が2~80モル%である、(iii)ポリエステル樹脂を構成するポリオール成分のうち、エチレングリコール成分と1,2-プロピレングリコール成分の共重合比率の合計が50モル%以上であり、エチレングリコール成分よりも1,2-プロピレングリコール成分を過剰に含む。
