WIPO Patent Application WO/2016/186138
Kind Code:
A1
Abstract:
The present invention relates to a treated surface metal sheet in which on at least one surface of a metal sheet, a surface treatment film layer containing a polycarboxylic acid polymer and a zirconium compound is formed, and on said surface treatment film layer, a coating film containing a polyester resin, a phenol resin and an acid catalyst is formed. Said treated surface metal sheet is a non-chromium-based treated surface metal sheet that is capable of providing cans and can lids: which have excellent dent resistance with respect to even acidic beverages, etc.; and for which there is no risk of an organic resin covering layer formed on said coating film delaminating even under high temperature/humidity conditions such as in disinfection treatment, and the organic resin covering layer has excellent hot water-resistant adhesiveness.
