  • Publication number: 20200399434
    Abstract: A method for producing a flexible-packaging film in which a first substrate and a second substrate are laminated with a reactive adhesive of a polyisocyanate composition (X) and a polyol composition (Y) therebetween includes a two-component separate application step in which a liquid mixture applied to the first substrate and including the polyisocyanate composition (X) and the polyol composition (Y), and a catalyst (Z) formed in a dot pattern on the second substrate are brought into contact with each other to achieve contact-bonding together. The substrates are preferably plastic films, metal vapor-deposition films, or metal foils. As the second substrate, a non-oriented film is preferably employed.

  • Patent number: 5869567
    Abstract: A polyester resin aqueous dispersion which provides a coating film having excellent processability, water resistance, corrosion resistance, chemical resistance, weather resistance and adhesion to various substrates, and which also has markedly excellent storage stability even at a high solids concentration. The polyester resin aqueous dispersion substantially comprises a specific polyester resin, a basic compound, an amphipathic organic solvent capable of plasticizing the polyester resin, and a compound having a protective colloid action. Furthermore, fine particles of the polyester resin are homogeneously dispersed in an aqueous medium and in a specific dispersed state.
