Abstract
In a thermoplastic resin laminate having at least three thermoplastic resin layers, wherein an intermediate layer interposed between a first layer of a thermoplastic resin A1 and a second layer of a thermoplastic resin B1, which are not bonded each other, is a thermoplastic resin composition which contains as a main component a thermoplastic resin A2 having a bonding property to the thermoplastic resin A1 and a thermoplastic resin B2 having a bonding property to the thermoplastic resin B1 and forms a dispersion structure, wherein the thermoplastic resin A2 forms a continuous phase and the thermoplastic resin B2 forms a dispersed phase in the intermediate layer at the vicinity of the interface between the intermediate layer and the first layer, and wherein the thermoplastic resin B2 forms the continuous phase and the thermoplastic resin A2 forms the dispersed phase in the intermediate layer at the vicinity of the interface between the intermediate layer and the second layer, the first layer and the second layer are firmly bonded by the intermediate layer.
