PURPOSE:To obtain a coating enabling the titled laminate provided with ultrathin coating film of both good appearance and physical properties to be manufactured, by incorporating either tolylene diisocyanate or polymethylenepolyphenyl isocyanate in a specific unsaturated polyester resin. CONSTITUTION:The objective coating can be obtained by incorporating ( I ) 100pts.wt. of a blend of (A) 20-80pts.wt. of an unsaturated alkyd resin with a hydroxyl value >=10 pref. 20-70 and number-average molecular weight of pref. 2,000-5,000 and (B) 80-20pts.wt. of a tricyclo(5,2,1,0<2.6>)deca-8-ylmethacrylate of formula I with (C) 0.01-10(pref. 0.01-2)pts.wt. of photopolymerization initiator and (D) 0.1-30(pref. 1-20)pts.wt. of either polymethylenepolyphenyl isocyanate or tolylene diisocyanate.
