Abstract:
1. An easy-open end comprising a resin-coated metal plate obtained by coating a metal substrate with an anti-blocking agent-containing biaxially drawn film via a primer, wherein: the anti-blocking agent is of a spherical shape having an average particle size of 0.5 to 2.5 μm and an average particle size ratio (long diameter/short diameter) in a range of 1.0 to 1.2, and is contained at a ratio of 0.05 to 0.5% by weight in the biaxially drawn film, and no top-coat layer is formed on the biaxially drawn film, and the primer is the one obtained by blending a single-terminal-modified epoxy resin having a number average molecular weight in a range of 3,000 to 8,000, the epoxy resin being modified with phenols or bisphenol, and an alkali resole-type phenol resin at a ratio (weight ratio) of 95:5 to 50:50.
