粘着剤の接着力は、組成物全体の軟化温度を下げることや樹脂成分の極性を上げる事で、上げることができる。
なお、当該接着力は、次のようにして測定される。即ち、端面保護部材の粘着剤組成物の層が形成されている面に低密度ポリエチレンフィルム(LDPE)シートをハンドローラーで貼り付ける。低密度ポリエチレンフィルムはタマポリ株式会社製GF-858を使用する。幅1inch、長さ15cmの短冊状にカットし、相対湿度50%、摂氏23度で11時間調湿する。株式会社オリエンテック製テンシロンRTM-500、ロードセル1kg、引張速度100mm/minで引張試験する。このとき、サンプルの端面保護部材をテンシロンの下部でチャック(固定)し、低密度ポリエチレンフィルムを引張部でチャック(固定)し、引張試験する。引張試験中、伸び10mmから50mmの区間で荷重の積分平均を取り、試験回数2回の平均を取り、これを接着性の値とする。
感光性樹脂積層体ロールは、異物の付着と輸送時の感光を抑制する観点から遮光シートで覆うことが好ましい。遮光シートは遮光性フィルムと呼ぶこともできる。遮光シートは、それを感光性樹脂積層体ロールに巻きつけるようにして覆うことができる。図3に示すように、遮光シート9が筒状である場合、感光性樹脂ロール1を筒内に挿入することで覆うことができるので好ましい。さらに筒の長さが感光性樹脂積層体ロール1の巻芯2より長い場合、図3に示すように、巻芯2より長い部分を巻芯内部へ折込むことにより、さらに異物の付着と感光を抑制することができるので好ましい。
遮光シートで感光性樹脂積層体ロールを覆う場合、遮光シートの巻芯より長い部分を巻芯内に折込み、その折込み部分を挟むようにしてさらにコアホルダーを装着すると、異物の付着と感光を抑制することができるので好ましい。
感光性樹脂組成物は、(a)カルボキシル基を含有するアルカリ可溶性高分子、(b)付加重合性モノマー、(c)光重合開始剤を含むことが好ましい。
リング状シートをロール端面から剥離する際に、ロール端面の糊残りが少なく、リング状シートへの感光性樹脂組成物の付着もすくなくなる観点から、感光性樹脂組成物が上記(a)~(c)を含むことが好ましい。
(a)カルボキシル基を含有するアルカリ可溶性高分子は、α,β-不飽和カルボキシル基含有単量体を重合成分としており、アルカリ可溶性高分子の酸当量が100~600、かつ、重量平均分子量が5,000~500,000であることが好ましい。カルボキシル基を含有するアルカリ可溶性高分子中のカルボキシル基は、感光性樹脂組成物がアルカリ水溶液から成る現像液又は剥離液に対して、現像性又は剥離性を有するために必要である。酸当量とは、その中に1当量のカルボキシル基を有するアルカリ可溶性高分子の質量を言う。酸当量のより好ましい下限は250であり、またより好ましい上限は450である。(a)カルボキシル基を含有するアルカリ可溶性高分子の酸当量は、現像耐性が向上し、解像度及び密着性が向上する点、さらに溶媒又は感光性樹脂組成物中の他の成分、特に後述する(b)付加重合性モノマーとの相溶性を確保するという観点から100以上が好ましく、現像性及び剥離性が向上する点から600以下が好ましい。酸当量の測定は、平沼産業(株)製平沼自動滴定装置(COM-555)を使用し、0.1mol/Lの水酸化ナトリウムを用いて電位差滴定法により行われる。
(a)カルボキシル基を含有するアルカリ可溶性高分子の重量平均分子量は、日本分光(株)製ゲルパーミエーションクロマトグラフィーを使用して、以下の条件で測定することができる:
示差屈折率計:RI-1530

最初に実施例及び比較例の評価用サンプルの作製方法を説明し、次いで、得られたサンプルについての評価方法及びその評価結果を示す。ここでは、ロール端面保護部材としてリング状シートを用いた。
1.評価用サンプルの作製
実施例及び比較例における評価用サンプルは次の様にして作製した。
<感光性樹脂積層体の作製>
下記表1に示す組成物1(但し、各成分の数字は固形分としての配合量(質量部)を示す。表1中の略号は表2に従う。)及び溶媒を十分に攪拌、混合して感光性樹脂組成物調合液とし、支持体として16μm厚のポリエチレンテレフタレートフィルム(三菱樹脂(株)製R310)を準備して、このポリエチレンテレフタレートフィルムの表面に感光性樹脂組成物調合液をダイコーターを用いて均一に塗布、乾燥し、感光性樹脂層を形成した。感光性樹脂層の厚みは15μmであった。次いで、感光性樹脂層の、ポリエチレンテレフタレートフィルムを積層していない表面上に、保護層として33μm厚のポリエチレンフィルム(タマポリ(株)製GF-858)を貼り合わせて感光性樹脂積層体1を得た。
また、上記感光性樹脂積層体1において、組成物1を組成物2~6とした以外は、感光性樹脂積層体1と同様に作成し、感光性樹脂積層体2~6を得た。上記感光性樹脂積層体1において、組成物1を組成物7~10とし、感光性樹脂層の厚みを10μmとした以外は、感光性樹脂積層体1と同様に作成し、感光性樹脂積層体7~10を得た。
リング状シートは、表3~表5に示すシートを用いた。リング状シートのアクリル樹脂を含む粘着剤組成物は、特に説明の無い場合、エリエールタック NS80/SBG85S/再剥離(エリエール テクセル株式会社製)の粘着剤組成物をそのまま使用した。
サンプルFおよびGについては粘着剤組成物は以下のようにして調整した。即ち、表2記載のB-1およびM-8を固形分比で45:55および40:60となるように配合し基材に乾燥後の膜厚が15μmとなるように塗布乾燥して調整した。
感光性樹脂積層体1を幅495mmにスリットし、内径77mm、外径88mm、長さ530mmのABS樹脂製巻芯(コア)に300m巻きつけた。ロール状に巻きつけられた感光性樹脂積層体の外径は180mmであった。
他端が固定されて水平に保持できるように設計された棒状のステンレス製ラックホルダーに、コアに巻きつけられロール状になった感光性樹脂積層体を保持させた。
外周500mm、長さ800mm、厚さ80μmの円筒形遮光性ポリエチレンチューブでロール状になった感光性樹脂積層体を覆った。
前記遮光性ポリエチレンチューブで覆われたロール状の感光性樹脂積層体をラックホルダーから取り外し、幅330mm高さ100mm上部が凹状に湾曲してロールが固定できるように設計されたクッションの上にロールを設置した。
遮光性ポリエチレンチューブの一端を折り返し、ロール状感光性樹脂積層体の端面を露出させ、リング状シートを装着した。もう一端も同様にしてリング状シートを装着し、感光性樹脂積層体ロール1を作成した。

(3)リング状シートの包装材貼りつき性
上記<感光性樹脂積層体ロールの作製>に記載の通りロールを作製した後、これを開梱した。開梱後も装着時と同様にリング状シートが端面に装着されているか観察し、以下のようにランク付けした。
