Definitions

  • gas barrier resins such as polyvinyl alcohol and ethylene-vinyl alcohol copolymer are provided as aqueous coating agents dissolved (dispersed) in an aqueous solvent containing water as the main component, so when drying The dryer must be set to a relatively high temperature. If such a resin is used to impart gas barrier properties to an oriented polyolefin film, which is inferior in heat resistance to a polyester film or a nylon film, the film may be deformed.
  • the present invention provides a two-component curable coating agent containing a polyester polyol (A), an isocyanate compound (B), an organic solvent (C), and a drying aid (D), and a laminate obtained using the coating agent.
  • Body packaging material.
  • polyhydric carboxylic acids and polyhydric alcohols that do not have a polymerizable carbon-carbon double bond may be used in combination.
  • polyhydric carboxylic acid and polyhydric alcohol those similar to polyester polyols (A1) and (A2) can be used.
  • Polyvalent carboxylic acid is preferably at least one selected from the group consisting of succinic acid, 1,3-cyclopentanedicarboxylic acid, orthophthalic acid, acid anhydride of orthophthalic acid and isophthalic acid, and orthophthalic acid and acid anhydride thereof.
  • the amount is preferably 30 parts by mass or less with respect to the total 100 parts by mass of the polyester polyol (A) and the polyol (E). It is more preferably 20 parts by mass or less, and more preferably 10 parts by mass or more.
  • anti-skinning agent (G) examples include propylene glycol monomethyl ether, ethyl cellosolve, propyl acetate, butyl acetate and the like.
  • Various surface treatments such as flame treatment and corona discharge treatment may be applied to the film surface as necessary so that a coating film free of defects such as film breakage and repellency is formed.
