There are provided (I) a laminate comprising: (i) a resin layer (A), which comprises a layer containing a propylene resin (a), (ii) a resin layer (B), which comprises a layer containing an acrylic resin (b) having a flexural modulus of from 100 to 1500 MPa, and (iii) a resin layer (C), which comprises a layer containing an acrylic resin (c), wherein the resin layers (A), (B) and (C) are laminated in this order, (II) a structure comprising said laminate, and (III) a process for producing said structure.

Laminate

Disclosed are a resin sheet that has a resin layer which is made up of a thermoplastic resin and which has a degree of orientation of not less than 0.0002 and not more than 0.0020, and a thermoformed article and laminate structure. The resin sheet is preferably employed in a thermoforming process. Particlarly favorable application of the resin sheet is a paintless film, which is usually thermoformed and then laminated to a molten resin.

Resin sheet, thermoformed article, and multilayer structure

Injection-molded product of propylene based resin composition

A multilayer molded article comprising a skin and a substrate consisting of a polypropylene resin composition having a crystallization rate of 45 second or less, said skin being integrally adhered to the substrate. Said multilayer molded article can be produced by feeding a skin material and a molten polypropylene resin composition having a crystallization rate of 45 second or less between a pair of upper and lower molds, molding the molten polypropylene resin composition in the molds with simultaneous adhering of the skin material to the surface of the molded resin composition and then cooling the molten resin composition to solidify the same. Said multilayer molded article has a small deformation degree without the soft feeling of the skin material being impaired.
