PROBLEM TO BE SOLVED: To obtain a PET-laminated metal plate cured by electron beam, improved in adhesivity, processability and finishing properties on the surface and excellent in retort resistance in a processing part by severe processing. SOLUTION: This electron beam curing type adhesive comprises (A) 100 pts.wt. of a carboxyl group-containing phenoxy resin as an esterified substance of a phenoxy resin and a polybasic carboxylic acid anhydride, having 1-100 acid value and 30,000-150,000 weight-average molecular weight, (B) 5-50 pts.wt. of a polycaprolactone having 5,000-70,000 number-average molecular weight and (C) a 2-50 pts.wt. of a polyester-based oligomer containing 0.3-12 equivalent/kg molecule of a polymerizable unsaturated double bond and having 300-5,000 number-average molecular weight. A PET film is stuck to a metal plate by using the adhesive and the adhesive cured by an electron beam to give a PET- laminated metal plate. |
