- the release agent component segregates on the surface of the release layer, so that the normal peeling force can be reduced. Further, since the release component oriented on the surface of the release layer is fixed by the cross-linking agent even after heating, the increase in the release force after heating is suppressed. On the other hand, if the ratio of the mold release agent / the cross-linking agent is 10.0 or more, the amount of the cross-linking agent is small, so that the mold release component may not be retained on the surface layer of the mold release layer when heated.

Abstract
Description
このように、長鎖アルキル系離型剤は、離型剤としての性能を十分に発揮できないという問題があり、その改善が要求されている。
[1]長鎖アルキル含有アクリル樹脂(A)および架橋剤(B)を少なくとも含み、実質的にシリコーン成分を含まない離型層が基材フィルムに積層されている離型フィルムであって、
前記離型層に含まれる長鎖アルキル含有アクリル樹脂の重量(a)と架橋剤の重量(b)の比率a/bが式(I)を満たすことを特徴とする請求項1に記載の離型フィルム:
(I)0.1≦a/b≦7.0。
[2]一態様において、本発明の離型フィルムにおける離型層は、更に離型剤(C)を含み、前記離型層に含まれる架橋剤の重量(b)と離型剤の重量(c)の比率c/bが式(II)を満たす。
(II)0.1≦c/b≦10.0
[3]一態様において、本発明の離型フィルムは、剥離速度0.3m/min.における常態剥離力(PF1)が8000mN/50mm以下である。
[4]一態様において、本発明の離型フィルムは、剥離速度0.3m/min.における加熱後(90℃,20h)剥離力(PF2)が、前記常態剥離力(PF1)の2倍以下である。
[5]一態様において、本発明の離型フィルムは、剥離速度30m/min.における加熱後(90℃,20h)剥離力(PF3)が、前記常態剥離力(PF1)の10倍以下である。
[6]本発明の別の態様において、本発明の離型フィルムの少なくとも一方の面上に、粘着層を積層した積層フィルムが提供される。
(I)0.1≦a/b≦7.0
によって、加熱前後のいずれにおいても剥離力が軽く、なおかつ高速剥離しても軽剥離を維持できる離型フィルムを見出した。
本発明の離型フィルムは、長鎖アルキル含有アクリル樹脂(A)および架橋剤(B)を少なくとも含み、実質的にシリコーン成分を含まない離型層と、基材フィルムから構成される。
本発明における離型フィルムは、基材と、前記基材の表面に配置された離型層とを備える。前記離型フィルムの離型層上に被離型体を配置すると、被離型体を基材と同様の形状に成形できる。また、離型層と被離型体とは容易に剥離するため、被離型体の形状を所望の形状に変形、維持することもできる。離型層は、基材の表面の一面に配置されていてもよいし、両面に配置されていてもよい。
本発明における離型層は、長鎖アルキル含有アクリル樹脂(A)および架橋剤(B)を少なくとも含み、実質的にシリコーン成分を含まない離型層である。例えば、長鎖アルキル含有アクリル樹脂(A)および架橋剤(B)を含む離型層形成組成物を硬化させることで、離型層を形成できる。一態様において、本発明の離型層は、更に離型剤(C)を含む。
本発明の離型層に含まれるバインダーとして、長鎖アルキル含有アクリル樹脂(A)が含まれる。
また、本発明の離型層に含まれるバインダーとしては、各種ポリマーを用いることができる。離型層は、ポリエステル樹脂、アルキッド樹脂、ウレタン樹脂、長鎖アルキル含有アクリル樹脂(A)以外のアクリル樹脂、エポキシ樹脂などを含むことが好ましい。さらに、前記樹脂は、長鎖アルキル基を有していることが好ましい。理論的に解析できているわけはないが、実験を重ねた結果、バインダー樹脂に長鎖アルキル基を有することで、後述の離型剤を離型層表面に効率よく配向させることができると考えられる。特に、本発明に係る長鎖アルキル含有アクリル樹脂(A)は、例えば、粘着剤を形成する粘着剤組成物に対し、良好な濡れ性を示すことができる。更に、本発明に係る長鎖アルキル含有アクリル樹脂(A)は、離型層の上に形成された粘着剤等の被離型体に対して、加熱前後のいずれにおいても、軽い剥離性を有し、なおかつ高速で剥離しても軽い離型性を維持する離型層フィルムを提供できる。
このように、長鎖アルキル含有アクリル樹脂(A)は、離型層におけるバインダーとしての機能に加え、離型性にも寄与できる。例えば、長鎖アルキル含有アクリル樹脂(A)の分子量は、500を超えることが好ましい。
以下、一例として、長鎖アルキル含有アクリル樹脂(A)の詳細を説明するが、マトリックスに含まれ得るポリエステル樹脂等においても、同様のことが該当する。
本発明の離型層の形成に用いる架橋剤(B)としては、ポリイソシアネート、メラミン、エポキシ、アルミニウムキレート、チタンキレート、紫外線硬化型樹脂、またはこれらの2種類以上の混合物を用いることができる。中でも、メラミンを用いることで硬化膜が剛直で、耐薬品性、耐候性に優れるため好ましい。アルミニウムキレート、チタンキレートでの架橋は、用途によっては金属成分の含有を嫌う場合がある。
(I)0.1≦a/b≦7.0。
一態様において、長鎖アルキル含有アクリル樹脂の重量(a)と架橋剤の重量(b)の比率a/bは、0.2以上5.0以下であり、例えば、0.2以上4.0以下であり、0.2以上2.5以下であってもよい。長鎖アルキル含有アクリル樹脂の重量(a)と架橋剤の重量(b)の比率a/bが上記範囲内となることで、長鎖アルキル含有アクリル樹脂(A)、必要によって更に添加されるバインダー樹脂が架橋剤によって架橋され、離型層の弾性率が向上するため、更に、剥離力を軽くできる。また、加熱後も架橋剤によって離型層表面に配向された離型成分が固定されているため、加熱後剥離力の上昇が抑制される。長鎖アルキル含有アクリル樹脂の重量(a)と架橋剤の重量(b)の比率a/bの比率が0.1以下であると、離型層表面に存在するバインダーの離型成分が少なくなるため、例えば、被離型体に粘着剤を用いる態様では、剥離力が重たくなる可能性がある。
また、長鎖アルキル含有アクリル樹脂の重量(a)と架橋剤の重量(b)の比率a/bが7.0以上であると架橋剤が少なくなるため、バインダーが十分に架橋されておらず、離型層強度が十分とならないおそれがあり、剥離力が大きくなる可能性がある。また、本問題は、高速で剥離した際により顕著になる傾向がある。
一態様において、離型層は、更に離型剤(C)を含む。本発明で用いる離型剤は、シリコーンを含まない長鎖アルキル基を含んだものが好ましく、低分子量ポリオレフィンワックス、長鎖アルキル系添加剤、高級アルコールなどが好ましい。これらの構造は、直鎖状または、分鎖状でも構わない。これらのうち、2種類以上の材料を混合して用いることもできる。
(II)0.1≦c/b≦10.0
例えば、本発明における離型剤の添加量としては、架橋剤の重量(b)と離型剤の重量(c)の比率c/bが7.0以下であることが好ましく、例えば、5.0以下である。また、比率c/bは、0.15以上であってもよい。
本範囲に離型剤/架橋剤の比率(c/b)を調整することで、離型剤成分が離型層表面へ偏析することによって常態剥離力を軽くできる。更に、加熱後も離型層表面に配向された離型成分が架橋剤によって固定されているため、加熱後剥離力の上昇が抑制される。
一方、離型剤/架橋剤の比率が10.0以上であると架橋剤が少ないため、加熱した際に、離型成分を離型層表層にとどめておくことできなくなる可能性があり、加熱後剥離力が重くなるおそれがある。
低分子量ポリオレフィンワックスとしては、たとえば、ポリエチレンワックス、ポリプロプレンワックスなどの低分子量のものが使用できる。
長鎖アルキル系添加剤としては、長鎖アルキル含有アクリル樹脂(A)以外のものを添加できる。例えば、ピーロイル1010やピーロイル1010S(以上、いずれも一方社油脂工業社製)などのアルキル鎖を有する低分子量添加物などが適時使用できる。上記の離型用の添加剤は所定の離型性を発現できる添加量を適時添加する。
高級アルコールとしては、直鎖状の高級アルコールとして、オクタノール、ノナノール、デカノール、ウンデカノール、ドデカノール、トリデカノール、テトラデカノール、ペンタデカノール、セタノール、ヘプタデカノール、ステアリルアルコール、エイコサノール、ドコサノールなどが挙げられる。
上記範囲内であると、常態剥離力が軽いため好ましい。常態剥離力が6000mN/50mm以上であると被離型体が搬送工程において剥がれる可能性が低く好ましい。加熱前の剥離力が8000mN/50mm以下であると、被離型体を剥離した際に、被離型体が変形する可能性が低く好ましい。
常態剥離力は、剥離速度0.3m/min.における常態剥離力を意味し、本発明に係る離型層上に配置した被離型体、例えば、粘着剤(一例として、アクリル系粘着テープ(日東電工社製、No.31B)等)を剥離する際の剥離力について評価できる。また、常態剥離力の測定は、常温(25℃)の条件下で行える。以下の加熱後剥離力においても、同様の被離型体を適用できる。

ラウリルメタクリレート(CH2=C(CH3)COOC12H25)、ヒドロキシエチルメタクリレート(CH2=C(CH3)COOC2H4OH)、メチルメタクリレート(CH2=C(CH3)COOCH3)を50:30:20の割合で混合し、固形分濃度が40重量%になるようにトルエンを加え、窒素気流下、アゾビスイソブチロニトリル(AIBN)を0.5モル%加えて共重合させ、長鎖アルキル含有アクリル樹脂を得た。
表1に記載の配合量で長鎖アルキル含有アクリル樹脂、架橋剤としてメラミン樹脂(日本カーバイド株式会社製、ニカラックMW-30)、低分子離型剤として高級アルコール(東京化成工業株式会社製、ペンタデカノール)、硬化触媒としてパラトルエンスルホン酸(日立化成ポリマー株式会社製、ドライヤー#900)を加え、さらに溶剤(トルエン/MEK=50/50:質量比)を加え、固形分濃度を6.0質量%とし、離型層塗工液を得た。
得られた離型層塗工液を、ポリエチレンテレフタレートフィルム(東洋紡社製、E5100、厚さ:38μm、表面粗さ(Sa):0.0365nm(コロナ処理面)、表面最大断面高さ(St):3.72、ヘイズ:3.7%)のコロナ処理面に、グラビアコーターを用いて塗布した後、130℃、30秒の条件にて乾燥を行い、厚さ0.2μmの離型層を形成した。得られた離型フィルムについて、常態剥離力、加熱後剥離力、加熱後高速剥離力の評価を行った。
組成を表1のものに変更した以外は、実施例1と同様の手順で離型層を形成した。得られた離型フィルムについて、常態剥離力、加熱後剥離力、加熱後高速剥離力の評価を行った。
本発明によれば、加熱前後のいずれにおいても、軽い剥離性を有し、なおかつ高速で剥離しても軽い離型性を維持する離型層フィルムを提供できる。一方、比較例1では、長鎖アルキル含有アクリル樹脂の重量(a)と架橋剤の重量(b)の比率a/bが本発明の範囲外であったため、加熱後高速剥離力(PF3)を測定できなかった。更に、加熱後に剥離力が増加し、離型層と粘着テープを剥離することができなかった。また、比較例2は、架橋剤(B)を含まないため、常温においても、粘着テープを離型層から剥離することができなかった。
