To improve the adhesion between layers in a layered body when the layered body is formed through lamination and integration by thermal molding.SOLUTION: A two-part reactive composition according to an embodiment is used for forming a thermoplastic matrix resin for a thermoplastic resin composite material containing fibers as a reinforcing material. The two-part reactive composition comprises an active hydrogen component comprising an aromatic diamine having an alkylthio group and an isocyanate component comprising at least one diisocyanate selected from the group consisting of an aliphatic diisocyanate, an alicyclic diisocyanate and modified products thereof. The diisocyanate comprises a blocked diisocyanate in which at least one of isocyanate groups is blocked and a non-blocked diisocyanate in which isocyanate groups are not blocked.SELECTED DRAWING: Figure 1 【課題】熱成形により積層一体化して積層体を成形した場合に、当該積層体の層間での接着を向上する。【解決手段】実施形態に係る二液反応型組成物は、強化材として繊維を含む熱可塑性樹脂複合体の熱可塑性マトリックス樹脂を形成するために用いられる。該二液反応型組成物は、アルキルチオ基を有する芳香族ジアミンを含む活性水素成分と、脂肪族ジイソシアネート、脂環式ジイソシアネートおよびこれらの変性体からなる群から選択された少なくとも一種のジイソシアネートを含むイソシアネート成分と、を有する。該ジイソシアネートは、少なくとも一方のイソシアネート基がブロックされたブロック化ジイソシアネートと、イソシアネート基がブロックされていない非ブロック化ジイソシアネートと、を含む。【選択図】図１
