本発明の一実施形態である樹脂溶液組成物は、芳香族ポリスルホン、芳香族ポリアミドイミド、芳香族ポリエーテルイミド、芳香族ポリイミドおよび芳香族ポリアミド酸からなる群から選ばれる少なくとも1つの樹脂と;スルホン系溶媒と;エステル系溶媒、もしくはケトン系溶媒、またはエステル系溶媒とケトン系溶媒の両溶媒と、を含む。
[式(1)中、Ph1およびPh2は、それぞれ独立に、フェニレン基であり、前記フェニレン基上の1個の水素原子は、炭素数1~10のアルキル基、炭素数6~20のアリール基またはハロゲン原子で置換されていてもよく、前記フェニレン基上の2個以上の水素原子が置換されるときは、前記水素原子はそれぞれ独立に炭素数1~10のアルキル基、炭素数6~20のアリール基またはハロゲン原子で置換されていてもよい。]
[式(2)中、Ph3およびPh4は、それぞれ独立に、フェニレン基であり、前記フェニレン基上の1個の水素原子は、炭素数1~10のアルキル基、炭素数6~20のアリール基またはハロゲン原子で置換されていてもよく、前記フェニレン基上の2個以上の水素原子が置換されるときは、前記水素原子はそれぞれ独立に炭素数1~10のアルキル基、炭素数6~20のアリール基またはハロゲン原子で置換されていてもよく;Rは、炭素数1~5のアルキリデン基、酸素原子または硫黄原子である。]

なお、本実施形態の樹脂溶液組成物に係る芳香族ポリスルホンは、繰返し単位(1)~(3)を、互いに独立に、少なくとも2種有していてもよい。
本明細書では、「還元粘度」は、以下に示す方法により測定される。
測定対象の樹脂約1gを、N,N-ジメチルホルムアミドに溶解し、容量1dLの溶液を調製し、その濃度(C 単位:g/dL)を計算する。調製した溶液の粘度(η)を、オストワルド型粘度管により25℃で測定する。N,N-ジメチルホルムアミドの粘度(η0)を、オストワルド型粘度管により25℃で測定する。溶液の粘度(η)とN,N-ジメチルホルムアミドの粘度(η0)とから、比粘性率を下記式に従い、算出する。
比粘性率=(η―η0)/η0
比粘性率を、溶液の濃度(C)で除することにより得られる値を、還元粘度(単位:dL/g)とする。
本実施形態の樹脂溶液組成物において、スルホン系溶媒とエステル系溶媒とを含む場合、エステル系溶媒の含有量は、スルホン系溶媒とエステル系溶媒の含有量の合計に対して、15質量%以上85質量%以下であり、好ましくは20質量%以上80質量%以下であり、より好ましくは24質量%以上76質量%以下であり、特に好ましくは25質量%以上75質量%以下である。エステル系溶媒の含有量が15質量%未満の濃度では、樹脂の溶解性が低下し、樹脂溶液組成物の固化が生じる。また、エステル系溶媒の含有量が85質量%を超えると、樹脂溶液組成物の保存安定性が低下し、ゲル化が生じる。すなわち、エステル系溶媒の含有量が、15質量%以上であると、樹脂の溶解性が向上し、樹脂溶液組成物の固化が生じにくく、85質量%以下であると、樹脂溶液組成物の保存安定性が向上し、ゲル化が生じにくくなる。
なお、本明細書において、「ゲル化」とは、常温、大気雰囲気下で、樹脂溶液組成物が、流動性のない状態になることを意味する。
「固化」とは、常温、大気雰囲気下で、樹脂溶液組成物が、流動性のない白色の固体の状態になることを意味する。
「白濁」とは、室温、大気雰囲気下で、樹脂溶液組成物が、流動性はあるが、樹脂溶液組成物中に白い濁りが存在する状態になることを意味する。
「保存安定性が高い」、「保存安定性の向上」、「優れた保存安定性」とは、常温(例えば5~35℃)で少なくとも1週間保存しても均一透明であり、ゲル化しない状態であることを意味する。
なお、「均一透明」とは、樹脂溶液組成物中に濁りがない状態を意味する。
なお、流動性の有無や濁りの存在の有無は目視観察により判断する。
本実施形態に係る樹脂溶液組成物の製造方法の一例として、芳香族ポリスルホンを含む樹脂溶液組成物を製造する方法を説明する。芳香族ポリスルホンの製造方法としては、公知の方法を採用することができる。また、市販の芳香族ポリスルホンをそのまま使用してもよい。市販の芳香族ポリスルホンとしては、例えば、スミカエクセルPES4100P(住友化学株式会社製、ポリエーテルスルホン、還元粘度0.41dL/g)等の繰返し単位(1)からなるもの(すなわち、繰り返し単位(1)が100モル%であるもの)が挙げられる。また、その末端構造は、各々の樹脂の製法に従って決まるものであり、特に限定されないが、例えば、-Cl、-OH、-OR(Rはアルキル基)等が挙げられる。
例えば、樹脂溶液組成物の製造方法として、樹脂を溶媒に添加し、40~120℃、0.5~24時間、必要に応じて攪拌しながら、加熱溶解すること、を含む方法が挙げられる。
