Provided is a composite Al material for a drawn and ironed can from which a drawn and ironed can having brightness can be formed. In a resin coated metal plate used for forming a drawn and ironed can, a first resin layer () having a thickness of 0.02 to 2 &#x3bc;m is formed on a surface of an Al platewhich forms an outer surface of the can, and a second resin layerhaving a thickness of 1 to 40 &#x3bc;m is formed on a surface of the Al platewhich forms an inner surface of the can. In a penetration test using a TMA device, an insertion amount of a quartz pin when a load of 5 g is applied to the first resin layer at a temperature of 100&#xb0; C. is 20% or less of a film thickness of the first resin layer. Further, the first resin layer has a room temperature of 10 N/mmor more.

Composite Al material for drawn and ironed can

Disclosed is a resin-coated Al sheet with which a drawn and ironed can having a lustrous appearance can be formed. An upper limit of a thickness of an outer surface resin layer which covers an Al surface which becomes an outer surface of the can and has an arithmetical mean roughness (Ra) of 0.5 &#x3bc;m or less with a thickness which falls within a range of 0.02 &#x3bc;m to 6 &#x3bc;m is determined based on an arithmetical mean roughness (Ra) of the Al surface, wherein the upper limit of the thickness of a coating outer-surface resin layer is decreased when the arithmetical mean roughness (Ra) is increased.
