Abstract:
Provided are an acrylic resin layer laminate having excellent impact resistance and a manufacturing method of the same. The laminate includes a first acrylic resin layer, a thermoplastic resin layer, and a second acrylic resin layer in this order, in which the thermoplastic resin layer contains 71% or more of a component having a spin-spin relaxation time T2H in pulse NMR measurement of 0.03 ms or longer. The manufacturing method of the laminate includes: discharging, from a die, a molten resin laminate containing at least a melt of a resin composition (1) containing a (meth)acrylic resin, a melt of a resin composition containing a thermoplastic resin, and a melt of a resin composition (2) containing a (meth)acrylic resin; and cooling the discharged molten resin laminate to obtain a laminate.
