Document Type and Number:
Japanese Patent JP7195052
Kind Code:
B2
Abstract:
A resin-coated metal sheet according to the invention of the present application that can suppress occurrence of retort blushing (white spots) includes a metal sheet, and a resin layer A coated on at least one side of the metal sheet. The resin layer A contains a polyester resin as a principal component, and the polyester resin is a blend of 30 to 50 wt % of a polyester I having a melting point of 210° C. to 256° C. and 50 to 70 wt % of a polyester II having a melting point of 215° C. to 225° C. The resin layer A has, in X-ray diffraction thereof, a peak intensity ratio satisfying the following formulas (1) and (2): (I100)II/(I100)I≥1.5 . . . (1) and (I100)II/(I011)II<1.5 . . . (2). The (I100)II is a maximum peak intensity observed in a range of 2θ=22.5° to 24.0° in X-ray diffraction of the polyester II, the (I100)I is a maximum peak intensity observed in a range of 2θ=25.4° to 26.7° in X-ray diffraction of the polyester I, and the (I011)II is a maximum peak intensity observed in a range of 2θ=16.0° to 18.0° in X-ray diffraction of the polyester II.
