Description
本発明の粘着製品において、基材を形成するAS/ASA樹脂組成物は、A−S共重合体およびA−S−A共重合体を主成分として、且つA−S共重合体:A−S−A共重合体(重量比)=90:10〜20:80の割合で含んでいる。A−S共重合体と、A−S−A共重合体との割合としては、前記範囲の割合であれば特に制限されないが、好ましくはA−S共重合体:A−S−A共重合体(重量比)=85:15〜40:60(特に80:20〜60:40)である。A−S共重合体およびA−S−A共重合体の全重量に対して、A−S共重合体の割合が90重量%より多いと(すなわち、A−S−A共重合体の割合が10重量%より少ないと)、再剥離性が良好な粘着剤を用いていても、基材の引裂強度が低いことにより裂け防止性が低下し、粘着製品を被着体に貼付させた後に剥がす際に、粘着製品が裂けてしまい、容易に剥がすことができなくなり、再剥離性が低下する。一方、A−S共重合体およびA−S−A共重合体の全重量に対して、A−S共重合体の割合が20重量%より少ないと(すなわち、A−S−A共重合体の割合が80重量%より多いと)、基材の剛性が低下し、粘着製品を被着体に貼付させる際に、粘着製品が曲がったりして、容易に貼付させることができなくなり、ハンドリング性が低下する。
粘着剤層を構成する粘着剤としては、特に制限されず、例えば、アクリル系粘着剤、ゴム系粘着剤、ポリエステル系粘着剤、ウレタン系粘着剤、ポリアミド系粘着剤、エポキシ系粘着剤、ビニルアルキルエーテル系粘着剤、シリコーン系粘着剤、フッ素系粘着剤などの公知の粘着剤を用いることができる。また、粘着剤は、ホットメルト型粘着剤であってもよい。粘着剤は、単独で又は2種以上組み合わせて使用することができる。
本発明の粘着製品は、基材の少なくとも一方の面(両面または片面)に粘着剤層が形成された構成を有していれば特に制限されないが、粘着剤層を有するシート状物の形態を有している又は有することができるシート状粘着性製品であることが好ましい。具体的には、粘着製品としては、例えば、粘着シート(基材付き粘着シート)、粘着テープ(基材付き粘着テープ)、粘着フィルム、粘着ラベルなどが挙げられる。
・アクリロニトリル−スチレン共重合体A:構成単位としてのアクリロニトリル単位と、スチレン単位との割合が、アクリロニトリル単位:スチレン単位(モル比)=38:62であるアクリロニトリル−スチレン共重合体
・アクリロニトリル−スチレン−アクリルゴム共重合体A:構成単位としてのアクリロニトリル単位と、スチレン単位との割合が、アクリロニトリル単位:スチレン単位(モル比)=38:62であり、且つ構成単位としてのアクリルゴム単位の割合が、アクリロニトリル−スチレン−アクリルゴム共重合体に対して50重量%であるアクリロニトリル−スチレン−アクリルゴム共重合体
アクリロニトリル−スチレン共重合体A:70重量部に対して、アクリロニトリル−スチレン−アクリルゴム共重合体A:30重量部を混練し、カレンダー法(カレンダーロールの温度:180℃)により圧延して、厚さが60μmの粘着製品用基材(「粘着製品用基材A」と称する場合がある)を得た。
アクリロニトリル−スチレン共重合体A:98重量部に対して、アクリロニトリル−スチレン−アクリルゴム共重合体A:2重量部を混練し、カレンダー法(カレンダーロールの温度:180℃)により圧延して、厚さが60μmの粘着製品用基材(「粘着製品用基材B」と称する場合がある)を得た。
アクリロニトリル−スチレン共重合体A:10重量部に対して、アクリロニトリル−スチレン−アクリルゴム共重合体A:90重量部を混練し、カレンダー法(カレンダーロールの温度:180℃)により圧延して、厚さが60μmの粘着製品用基材(「粘着製品用基材C」と称する場合がある)を得た。
実施例1及び比較例1〜2で得られた各粘着シートについて、粘着力、貼付時のハンドリング性、貼り直し作業性を、下記の評価方法又は測定方法により評価又は測定した。評価結果は、表1に示した。
実施例1及び比較例1〜2で得られた各粘着シートを幅20mmに切断して、粘着製品サンプルを作製した。この粘着製品サンプルを、被着体としての無着色のABS樹脂製板(アクリロニトリル−ブタジエン−スチレン系樹脂製板)に、2kgのローラーを1往復させて貼付し、23℃且つ50%RHの環境下で30分間放置させた後、粘着製品サンプルを、引張試験機を用いて、23℃、50%RHの雰囲気中にて、剥離角度:180°、引張速度:300mm/分で、被着体から剥離させて、その際の剥離に要する力(粘着力)を測定した。
実施例1及び比較例1〜2で得られた各粘着シートを、30mm×50mmの大きさに切断して、粘着製品サンプルを作製した。この粘着製品サンプルを、手作業で、板の所定の決められた位置に貼り付ける作業を行い、その際の作業性(貼付時のハンドリング性)を以下の評価基準により、官能的に評価した。

×:粘着製品用基材の剛性不足等により、決められた位置に容易に貼り付けることができない。
実施例1及び比較例1〜2で得られた各粘着シートを、30mm×50mmの大きさに切断して、粘着製品サンプルを作製した。この粘着製品サンプルを、手作業で、ABS樹脂製板に貼り付け、1分後に、端部から爪で引っ掛けて剥がす作業を行い、その際の作業性(貼り直し作業性)を以下の評価基準により、官能的に評価した。
評価基準
○:容易に剥がすことができる。
×:粘着製品用基材が裂けることにより、容易に剥がすことができない。
