前記基材層の少なくとも一方の面に設けられ、かつ、上記[1]乃至[6]いずれか1つに記載のガスバリア性重合体を含むガスバリア層と、
を備えるガスバリア性積層体。
本実施形態において、ガスバリア性重合体は、ポリカルボン酸およびポリアミン化合物を含む混合物を加熱硬化してなる。そして、かかるガスバリア性重合体の赤外線吸収スペクトルにおいて、1493cm-1における測定点と1780cm-1における測定点とを結ぶ直線をベースラインとして設定し、1660cm-1における吸収強度をI(1660)とし、1625cm-1における吸収強度をI(1625)としたとき、下記式(1)で示されるRが1より大きい。
R=I(1660)/I(1625)-{-0.65×(全アミン/COOH)+0.4225} (1)
(上記式(1)中、「全アミン」は、混合物中のポリアミン化合物に含まれる1級、2級および3級アミノ基のモル数の合計であり、「COOH」は、混合物中のポリカルボン酸に含まれる-COOH基のモル数である。)
すなわち、本発明者らは、ポリカルボン酸およびポリアミン化合物を含む混合物を加熱硬化してなるガスバリア性重合体について、生産性およびレトルト処理後のガスバリア性を向上させるために鋭意検討を重ねた。その結果、I(1625)に対するI(1660)の比という尺度が、ガスバリア性重合体の生産性およびレトルト処理後のガスバリア性の向上のための設計指針として有効であることを見出した。
さらに具体的には、ポリカルボン酸およびポリアミン化合物を含む混合物を加熱硬化してなるガスバリア性重合体は、ポリカルボン酸およびポリアミン化合物を含む混合物の架橋体により構成される。この架橋体には、イオン架橋およびアミド架橋の2種類の架橋構造が存在し、これらの架橋構造の分布状態の制御がガスバリア性能を向上させる観点において重要であることが明らかになった。架橋構造のうち、イオン架橋とは、ポリカルボン酸に含まれるカルボキシル基とポリアミン化合物に含まれるアミノ基とが酸塩基反応を起こすことによって生成するものである。また、アミド架橋とは、ポリカルボン酸に含まれるカルボキシル基とポリアミン化合物に含まれるアミノ基とが脱水縮合反応を起こすことによって生成するものである。そして、本発明者らがさらに検討したところ、上記の2種の架橋構造のうち、アミド架橋の形成状態が、架橋体のIRスペクトル中のI(1625)およびI(1660)に反映されること、そして、I(1625)に対するI(1660)の比という尺度を設計指針とすることにより、レトルト処理後のガスバリア性に優れる架橋体を短時間で効率良く形成できることが明らかになった。
式(1)において、Rが1より大きいことは、架橋体中にアミド架橋点が好ましい分布状態で形成されており、架橋体のレトルト処理後のガスバリア性に優れるとともに、かかる架橋体が短い熱処理時間で効率良く形成されることを示していると考えられる。
<スペクトル(SBN')>=<スペクトル(SBN)>-α*<スペクトル(SSN)>
ここで、αは、基材の影響を除くための係数で、0≦α<1である。αの具体的な決定方法については実施例の項で後述する。そして、上記の解析を通じて有られたスペクトル(SSN')において、1660cm-1におけるIR強度がI(1660)、1625cm-1におけるIR強度がI(1625)である。
(全アミン/COOH)は、ガスバリア性組成物中のカルボキシル基のモル数に対する全アミン成分のモル数の比であり、ポリカルボン酸およびポリアミン化合物の配合比率から計算することができる。一方、配合比率が不明な場合は、たとえば、ガスバリア性重合体の組成分析により近似的に決定することができる。具体的には、ガスバリア性重合体がポリアクリル酸またはポリメタクリル酸とポリアミン化合物との混合物を加熱硬化して形成されるとき、得られたガスバリア性重合体中のNおよびOの原子比率をX線光電子分光法(XPS)で求めることにより、(全アミン/COOH)を以下の式にて算出することができる。
(全アミン/COOH)=[N]/{0.5*[O]}
(上記式中、[N]および[O]は、それぞれ、ガスバリア性重合体中のNおよびOの原子比率である。)
また、Rの上限に制限はないが、ガスバリア性重合体の生産性向上の観点から、Rはたとえば1.50以下、であり、好ましくは1.40以下である。

また、本実施形態において、ポリメタクリル酸とは、メタクリル酸の単独重合体、メタクリル酸と他のモノマーとの共重合体の両方を含む。メタクリル酸と他のモノマーとの共重合体の場合、ポリメタクリル酸は、重合体100質量%中に、メタクリル酸由来の構成単位を、通常は90質量%以上、好ましくは95質量%以上、より好ましくは99質量%以上含む。

まず、ポリカルボン酸に、塩基を加えることによりポリカルボン酸のカルボキシ基を完全にまたは部分的に中和する。次いで、カルボキシ基を完全にまたは部分的に中和したポリカルボン酸にポリアミン化合物を添加する。このような手順でポリカルボン酸およびポリアミン化合物を混合することにより、ポリカルボン酸およびポリアミン化合物の凝集物の生成を抑制でき、均一な混合物を得ることができる。これにより、ポリカルボン酸に含まれる-COOH基とポリアミン化合物に含まれるアミノ基との脱水縮合反応をより効果的に進めることが可能となる。
ポリカルボン酸の中和物は、ポリカルボン酸の水溶液に塩基を添加することにより調製するが、ポリカルボン酸と塩基の量比を調節することにより、所望の中和度とすることができる。本実施形態においてはポリカルボン酸の塩基による中和度は、ポリアミン化合物のアミノ基との中和反応に起因するゲル化を十分に抑制する観点から、好ましくは30~400当量%であり、より好ましくは40~300当量%、さらに好ましくは50~250当量%である。

加熱処理の方法については、上記の観点から選択され、たとえば、混合物を硬化させられるもの、硬化したガスバリア用塗材を加熱できる方法であればよい。具体例として、オーブン、ドライヤー等の対流伝熱によるもの、加熱ロール等の伝導伝熱によるもの、赤外線、遠赤外線・近赤外線のヒーター等の電磁波を用いる輻射伝熱によるもの、マイクロ波等内部発熱によるものが挙げられる。乾燥、加熱処理に使用する装置としては製造効率の観点から乾燥と加熱処理の双方をおこなえる装置が好ましい。その中でも具体的には乾燥、加熱、アニーリング等に利用できるという観点から熱風オーブンを用いることが好ましく、また、フィルムへの熱伝導効率に優れているという観点から加熱ロールを用いることが好ましい。また、乾燥、加熱処理に使用する方法を適宜組み合わせてもよい。熱風オーブンと加熱ロールを併用してもよく、たとえば、熱風オーブンで混合物を乾燥後、加熱ロールで加熱処理をおこなえば加熱処理工程が短時間となり製造効率の観点から好ましい。また、熱風オーブンのみで乾燥と加熱処理をおこなうことが好ましい。熱風オーブンを用いて、混合物を乾燥させる場合、加熱処理温度は160~250℃、加熱処理時間は1秒~10分、好ましくは加熱処理温度が180~240℃、加熱処理時間が2秒~8分、より好ましく加熱処理温度が200℃~230℃、加熱処理時間が2秒~6分、さらに好ましくは加熱処理温度が200℃~220℃、加熱処理時間が3秒~5分の条件で加熱処理をおこなうことが望ましい。さらに上述したように加熱ロールを併用することで短時間での加熱処理が可能となる。なお、ポリカルボン酸に含まれる-COOH基とポリアミン化合物に含まれるアミノ基との脱水縮合反応を効果的に進める観点から、加熱処理温度および加熱処理時間は、混合物のウエット厚みに応じて調整することが重要である。
本実施形態において得られるガスバリア性重合体は、生産性に優れるとともに、レトルト処理後のガスバリア性に優れるものである。さらに具体的には、本実施形態により、レトルト処理後の酸素ガスバリア性に優れるガスバリア性重合体を短時間の加熱処理で得ることができる。

得られた積層体について、以下の評価をおこなった。評価結果を表2および表3にあわせて示す。表2および表3には、ポリカルボン酸として、それぞれ、重量平均分子量10万および80万のものを用いた場合を示す。
得られた積層体について、それぞれ1cm×3cmの測定用サンプルを切り出した。次に、その積層体のガスバリア性重合体層側表面の赤外線吸収スペクトルを赤外線全反射測定(ATR-IR法)により得た。測定には、日本分光社製FT/IR-460装置を用い、多重反射測定ユニットATR PRO410-M(プリズム:Germanium結晶、入射角度45度、多重反射回数=5)を装着し、室温で、分解能2cm-1、積算回数150回で測定した。PET基材も測定サンプルとして用意し、同じようにして、PET基材表面の赤外線吸収スペクトルを測定した。
得られた積層体の赤外線吸収スペクトルには、PET基材の影響を含むため、一般的な差スペクトル解析法によりPET基材の影響を除いた。具体的には、以下に示す手法を用いた。
積層体とPET基材の赤外線吸収スペクトルは、1493cm-1における測定点と1780cm-1における測定点とを直線(ベースライン:N)で結び、1493cm-1~1780cm-1の波数範囲において、赤外線吸収スペクトルとNとの差スペクトルを得て、それぞれスペクトル(SBN)、スペクトル(SSN)とした。さらに、積層体とPET基材の赤外線吸収スペクトルの1325cm-1における測定点と1355cm-1における測定点とを直線(ベースライン:M)で結び、1325cm-1~1355cm-1の波数範囲において、得られた赤外線吸収スペクトルとMとの差スペクトルを得て、それぞれスペクトル(SBM)、スペクトル(SSM)とした。スペクトル(SBM)のIRピークは、PET基材だけの影響で現れるIRピークとなるように波数範囲を選び、スペクトル(SBN)におけるPET基材の影響を除くための基準ビークとした。スペクトル(SBM)及びスペクトル(SSM)について、1325cm-1以上1355cm-1以下のピーク面積をそれぞれ面積(ABM)、面積(ASM)とし、係数αを次式から計算した。係数αは、0≦α<1となる。
α=面積(ABM)/面積(ASM)
この係数αを使って、1493cm-1から1780cm-1の波数範囲において、次式に従った差スペクトル解析を行い、PET基材の影響を除いたスペクトル(SBN')を得た。
<スペクトル(SBN')>=<スペクトル(SBN)>-α*<スペクトル(SSN)>
そして、上記の解析を通じて有られたスペクトル(SBN')の1660cm-1におけるIR強度をI(1660)、1625cm-1におけるIR強度をI(1625)とし、IR強度比I(1660)/I(1625)を計算した。
また、スペクトル(SBN')において、1493cm-1以上1780cm-1以下の波数範囲における全ピーク面積をA、1598cm-1以上1690cm-1以下の波数範囲における全ピーク面積をBとしたとき、アミド結合の面積比率を(B/A)として計算した。
厚さ70μmの無延伸ポリプロピレンフィルム(三井化学東セロ社製 商品名:RXC-22)の片面に、エステル系接着剤(ポリウレタン系接着剤(三井化学社製 商品名:タケラックA525S):9質量部、イソシアネート系硬化剤(三井化学社製 商品名:タケネートA50):1質量部及び酢酸エチル:7.5質量部)を塗布し乾燥後、各配合に基づき得られた積層体のバリア面と貼り合わせ(ドライラミネート)、多層フィルムを得た。
上記で得られた多層フィルムを無延伸ポリプロピレンフィルムが内面になるように折り返し、2方をヒートシールして袋状にした後、内容物として水を入れ、もう1方をヒートシールにより袋を作製し、これを高温高圧レトルト殺菌装置で130℃、30分間の条件でレトルト処理を行った。レトルト処理後、内容物の水を抜き、レトルト処理後の多層フィルムを得た。
そして、レトルト処理後の各多層フィルムの酸素透過性を、モコン社製OX-TRAN2/21を用いて、JIS K 7126に準じ、温度20℃、湿度90%RHの条件で測定した。結果を図3、図4、表2および表3に示す。
実験例1に準じて、各種ポリカルボン酸およびポリアミン化合物を混合し、塗工液塗工後の加熱時間をいずれも240秒として積層体を作製し、評価した。結果を表4および図5に示す。
本例では、無機物層を含むガスバリア性積層体を作製し、評価した。
基材層としては、以下のいずれかを用いた。
基材層1:PETフィルム
基材層2:アンダーコート層付きPETフィルム
なお、基材層1は、厚さ12μmの二軸延伸ポリエチレンテレフタレートフィルム(ユニチカ社製、商品名PET12)を用いた。基材層2は、下記の手順で作成した。まず、ロールコーターにより、厚さ12μmの二軸延伸ポリエチレンテレフタレートフィルム(ユニチカ社製、商品名PET12)のコロナ処理面に、乾燥後の塗工量が0.2g/m2になるように、ウレタン系のアンダーコート層を塗工し、アンダーコート層付きPETフィルムを得た。
さらに、基材層1のコロナ処理面に、高周波誘導加熱方式のロール蒸着装置により、アルミニウムを加熱蒸発させ、酸素を導入しながら蒸着することで、無機物層として厚さ7nmの酸化アルミニウム膜を形成させた。また、基材層2のアンダーコート層上にも、基材層1と同条件で無機物層を形成させた。
実験例1に準じて、塗工液(X3-2)および(V3-2)を調製した。基材層1または基材層2の無機物層を形成した面にエアーフローティング型の加熱炉を備えたロールコーターを用いて塗工液を所定量塗布し、210℃にて所定時間熱処理してガスバリア層を形成し、無機物層を含むガスバリア性積層体を得た。尚、熱処理時間は、210℃に設定した加熱ゾーンの通過時間とし、加熱ゾーンの長さと基材の搬送速度から計算した。
得られたガスバリア性積層体は、実験例1と同様にして、IR測定及び解析を行った。但し、基材の影響を除去する差スペクトル解析には、PET基材に代えて、無機物層を形成した基材1及び基材2を用いた。また、実験例1と同様にして、厚さ70μmの無延伸ポリプロピレンフィルムと貼り合わせた多層フィルムを作製し、レトルト処理後の酸素透過性を評価した。結果を表5および図6に示す。
