Resin-coated metal sheet for container

A resin-coated metal sheet for containers, comprising:

• a metal sheet;
• a resin layer (A) having a multilayer structure and containing a polyester as a main component, the polyester being a polymer of an acid component and a glycol component, the resin layer (A) being disposed on a side which, after the metal sheet is formed into a container, becomes an inner side of the container;
• and
• a resin layer (B) containing a polyester as a main component, the resin layer (B) being disposed on a side that becomes an outer side of the container,
• wherein:
• i) the acid component, which is a constitutional unit of the polyester contained as the main component of the resin layer (A), comprises a terephthalic acid unit in an amount of at least 85 mol %,
• ii) the resin layer (A) includes an uppermost resin layer (a1) that is configured to be in contact with contents of the container, the uppermost resin layer (a1) containing a wax component in an amount of 0.10 to 2.0 mass % with respect to a mass of the uppermost resin layer (a1) and having a thickness within a range of 0.5 μm or more and 10 μm or less,
• iii) the ratio (I2968/I3085) of a Raman band intensity (I2968) at 2,968±5 cm−1 measured by Raman spectroscopy on a surface of the resin layer (a1) to a Raman band intensity (I3085) at 3,085±5 cm−1 measured on the surface of the resin layer (a1) is 0.6 or more and 0.9 or less,
• iv) the resin layer (B) contains a polyester (I) that is polyethylene terephthalate or copolymerized polyethylene terephthalate containing 15 mol % or less of a copolymerization component and a polyester (II) that is polybutylene terephthalate or copolymerized polybutylene terephthalate containing 15 mol % or less of a copolymerization component,
• v) the ratio of the polyester (I) to the polyester (II) is 10:90 to 60:40 based on mass %, and
• vi) the ratio (I2968/I3085) of a Raman band intensity (I2968) at 2,968±5 cm−1 measured by Raman spectroscopy on a surface of the resin layer (B) to a Raman band intensity (I3085) at 3,085±5 cm−1 measured on the surface of the resin layer (B) is 0.8 or more and 1.0 or less.
