Abstract:
1. A resin-coated metal material comprising a metal material at least partially coated with a sheet of a polyolefin resin composition, wherein said polyolefin resin composition comprises: components (A), (B), (C), and (D) wherein (A) is a polyolefin resin, (B) is an organified layered inorganic material, (C) is an olefin-containing oligomer having a repeating unit of —CR wherein R (D) is a rubber-like elastic material having a repeating unit of —CR wherein R wherein said layered inorganic material (B) and said rubber-like elastic material (D) are dispersed in said polyolefin resin (A), wherein a dispersion diameter of the layered inorganic material (B) is from 50 to 300 nm, and an aspect ratio of a long side to a thickness of one crystalline inorganic material layer is from 100 to 500, wherein a long diameter of said rubber-like elastic material (D) is 3 μm or less, the ratio between the long axis and the short axis of the dispersion diameter of the rubber-like elastic material (D) is from 1 to 20, the ratio (MFR(A)/MFR(D)) between a melt flow index (MFR(A)) of said polyolefin resin (A) and a melt flow index (MFR(D)) of said rubber-like elastic material (D) is from 0.1 to 10, wherein a dispersion diameter of the olefin-containing oligomer (C) is from 1 to 100 nm and the ratio between the long axis and the short axis of the dispersion diameter of the olefin-containing oligomer (C) is 2 or less, wherein a thickness of the resin sheet is from 0.5 μm to 50 mm, and the layered inorganic material (B) is oriented in the direction parallel to a sheet plane, and wherein said resin composition has a formulation such that the polyolefin resin (A) is 20 mass % or more based upon the total mass of the resin composition, the layered inorganic material (B) is from 0.01 to 30 mass % based upon the total mass of the resin composition, the olefin-containing oligomer (C) containing a functional group having polarity is from 3 to 60 mass % based upon the total mass of the resin composition, and the rubber-like elastic material (D) is from 1 to 30 mass % based upon the total mass of the resin composition.
