PURPOSE: To obtain the laminated molded object excellent in durability, while the covering layer with uniform, sufficient and optional thickness may be obtained on the whole range of the laminated formed object by polymerizing, with solidification, the synthetic resin which contains a polymer and pas fluidity onto the crystalline resin or synthetic resin-base mainly by heating them in a mold.
CONSTITUTION: A synthetic resin covering layer is molded by polymerizing, with solidification, under heating the synthetic resin material which contains monomer and has fluidity in a mold. Synthetic resin base is mainly made of crystalline resin or the mixture of crystalline resin with amorphous resin, whereby said resin base becomes the material excellent in chemical resistance. Further, while a decorative member or a primer is caused to intervene between the synthetic resin covering layer and the synthetic resin base, their linear expansion factors are approximated, whereby the warpage of the laminated molded object due to surrounding temperature-change or the crack and peeling of the synthetic resin covering layer are avoided.
