Abstract
A coated metallic sheet adapted for use in making a can for foodstuff or other container. This sheet can be made by coating, upon a material sheet, a composition of a resol-type thermosetting phenolformaldehyde resin and a bisphenol "A" type epoxy resin. In said phenol-formaldehyde resin, the ratio by weight of orthocresol to phenol is between 60:40 and 10:90. Said epoxy resin has a mean molecular weight of 800 or more and is used in an amount of 0.2 to 1.5 part by weight per 1 part by weight of said phenol-formaldehyde resin in said composition. This composition used for the sheet displays an excellent adhesiveness particularly with respective to the use of a polyamide type adhesive.
