Beschreibung
Zusammenfassung:	To provide a hot melt type adhesive which can stick and bond a road surface display material and a guide panel onto a road surface, and prevents occurrence of adhesive failure in bonding by heating, and to provide a hot melt type adhesive which prevents peeling and deviation when a vehicle passes, brakes or changes its direction even at high temperatures in a summer season and low temperatures in a winter season after bonding.SOLUTION: A hot melt type adhesive for sticking a road surface display material contains specific amounts of a block copolymer (A) of a polymer block including a structural unit derived from alkyl methacrylate having a 1-3C alkyl group and a polymer block including a structural unit derived from acrylic acid alkyl ester having a 1-8C alkyl group, a tackifier (B) having a softening point of 130°C or higher, and a tackifier (C) having a softening point of lower than 130°C, and has a softening point of 90°C or higher.SELECTED DRAWING: None 【課題】道路面表示材や誘導パネルを道路面へ貼り合わせて接着することができ、加熱により貼り合わせる際に、接着不良が発生し難いホットメルト型接着剤を提供すること。また、貼り合わせた後に、夏場の高温や冬場の低温時でも、車両などが通過、制動又は方向転換した際に、剥がれやズレが発生しないホットメルト型接着剤を提供すること。【解決手段】アルキル基の炭素数が１～３のメタクリル酸アルキルエステルに由来する構造単位を含む重合体ブロックとアルキル基の炭素数が１～８のアクリル酸アルキルエステルに由来する構造単位を含む重合体ブロックとのブロック共重合体（Ａ）と、軟化点が１３０℃以上の粘着付与剤（Ｂ）と、軟化点が１３０℃未満の粘着付与剤（Ｃ）とを特定量含み、軟化点が９０℃以上の道路面表示材貼付け用ホットメルト型接着剤。【選択図】なし
