Abstract: A laminate (10) includes a substrate (11), a sealing layer (12A) disposed on a surface of the substrate (11), and a coating layer (13) disposed on a surface of the substrate (11) opposite to the sealing layer (12A). The coating layer (13) contains a tannic acid derivative in which at least a part of a plurality of hydroxyl groups is substituted with a linear hydrocarbon group having 1 to 18 carbon atoms, and at least one type of resin selected from the group consisting of a urethane resin, an acrylic resin, a vinyl chloride-vinyl acetate copolymer resin, a polyester resin, and an olefin resin.

Abstract: A method for separating and recovering a layered film laminated and adhered with an adhesive, the method including a step 1 of immersing the layered film in a morpholine solution having a morpholine concentration of 50% by mass or more while stirring the layered film with heating at 20° C. to 90° C. or ultrasonically vibrating the layered film and a step 2 of recovering separated single-layered films that constitute the respective layers of the layered film. The adhesive is preferably a reactive adhesive containing a polyisocyanate composition and a polyol composition.

Abstract: A method for separating and recovering a layered film laminated and adhered with a reactive adhesive, the method including a step 1 of immersing the layered film in an alkaline solution while stirring the layered film with heating at 20° C. to 90° C. or ultrasonically vibrating the layered film and a step 2 of recovering separated single-layered films that constitute the respective layers of the layered film. The reactive adhesive is preferably a reactive adhesive containing a polyisocyanate composition and a polyol composition and more preferably a reactive adhesive containing a polyisocyanate composition, a polyol composition, and a compound having an acidic group.

Abstract: The present invention provides an excellent radiation curable aqueous coating composition, which is highly safe and can make the adhesion to a metal surface and the corrosion resistance compatible which have been considered to conflict with each other, particularly adhesion after severe working and solvent resistance, and particularly durability to alcohols having high polarity. The composition of the present invention contains (1) a phosphoric acid ester compound having an ethylenically unsaturated double bond, (2) an aqueous polyurethane resin having both an ethylenically unsaturated double bond and a group capable of forming a salt, and (3) colloidal silica.
