  • Publication number: 20230212444
    Abstract: Provided are a two-component curable adhesive which can be aged at room temperature and has favorable adhesiveness to various base materials, a laminate in which the adhesiveness between a base material and an adhesive is excellent even when aged at room temperature, and a packaging material including the laminate. The two-component curable adhesive includes a polyisocyanate composition (X) including a polyisocyanate compound (A) and a polyol composition (Y) including a polyol (B), in which a viscosity of the polyol composition at 50° C. is 20 mPa·s or more and 180 mPa·s or less.

  • Publication number: 20210332275
    Abstract: Provided is a solventless two-component adhesive having excellent processed appearance and processability while exhibiting excellent adhesive strength even with aging at room temperature (around 25° C.) and in a short period of 12 hours. Provided are a two-component curable adhesive containing a polyisocyanate composition (X) containing a polyisocyanate (A) and a resin composition (Y) containing a polyol (B) as essential components, the two-component curable adhesive satisfying (1) to (3), as well as a laminated film and a packaging body produced using the two-component curable adhesive: (1) a tensile shear adhesive strength (N1) when provided between two bases and after a lapse of 30 minutes after pressure bonding is 0.

  • Patent number: 8440749
    Abstract: The present invention provides a primer for a laminate for packaging having print suitability, such as excellent transfer properties of printing ink and dot reproducibility, high adhesive properties, excellent storage stability for a long period of time under highly humid conditions, and acid resistance which are obtained by improving adhesion between the base layer, a printing ink layer, a coating layer, and an adhesive layer; and a laminate containing the primer layer, and the primer containing: a main component (A) containing a copolymer containing, as a monomer, an unsaturated compound (a) having a hydroxyl group, and at least one unsaturated compound (b) selected from the group consisting of unsaturated carboxylate, styrene, unsaturated carboxylic acid, unsaturated hydrocarbon, vinyl ester, and a halogenated vinyl compound; a curing agent (B) containing a compound having an isocyanate group; and a compound (C) having 2 or more of a carboxylic acid group or 1 or more of an anhydrous carboxylic acid group.

  • Patent number: 4451167
    Abstract: The invention provides a printing device in which a cutter unit for printing medium is rotatably supported by a pivot on the printing device body and located in such a position as to permit the printing head to be covered or exposed. The cutter unit, in its closed inoperable state, is interlockingly operated through an engaging lever by a separate drive system housed in the device body, but may be brought into or out of an interlocking engagement with the drive system, whereby a series of maintenance and checking operations such as the mounting and replacement of the ink ribbon, the cleaning of the interior of the printing device body and the removal of a jammed paper are carried out.
