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 2?=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 2?=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 2?=16.0° to 18.

Abstract: [Problem] To provide: a resin-coated metallic plate which cannot undergo the occurrence of a retort brushing phenomenon (the formation of white spots) or the delamination of a film under retort sterilization treatment conditions; and others. [Solution] A resin-coated metallic plate having a resin layer (A) and a resin layer (B) is characterized in that the resin layer (A) contains 50 to 80 wt % of a polyethylene terephthalate-based resin (I) and 20 to 50 wt % of a polybutylene terephthalate-based resin (II), wherein the resin layer (B) contains 50 to 80 wt % of a polyethylene terephthalate-based resin (III) and 20 to 50 wt % of a polybutylene terephthalate-based resin (II), the polyethylene terephthalate-based resin (I) has a melting point of 210 to 230 ° C. inclusive, the polybutylene terephthalate-based resin (II) has a melting point of 215 to 225° C. inclusive, and the polyethylene terephthalate-based resin (III) has a melting point of higher than 230° C. and 205° C. or lower.
