Abstract: Provided is a method for producing a gas barrier paper packaging material which can impart sufficient gas barrier properties even when a barrier coating agent for forming a barrier layer is applied in a dry amount of 2 g/m2 or less. The method for producing a gas barrier paper packaging material at least includes: a barrier layer forming step of applying a barrier coating agent to one side of a sealant film to form a barrier layer; and a lamination step of laminating the barrier layer and a paper substrate layer via an adhesive layer.

Abstract: The present invention provides an anchor coating agent that has an appropriate viscosity, can reduce or inhibit the misting phenomenon, can be uniformly transferred in a required amount to a print medium, and can provide a coating film with excellent coating film durability. The present invention relates to an anchor coating agent containing: an emulsion; at least one of a cellulose ether or polyvinyl alcohol; and an aqueous medium.

Abstract: Provided is an anchor coating agent which is excellent in storage stability and can form an anchor coat layer excellent in inkjet printability, coating film durability, and hiding power. The present invention relates to an anchor coating agent containing a white pigment, an ionic salt, and an aqueous resin having an acid value of 50 mgKOH/g or less.

Abstract: A notebook personal computer 50 of a built-in MODEM type has a printed board assembling member 57 incorporated into a notebook personal computer main body 51. A notebook personal computer 80 of a built-in LAN type has a printed board assembling member 82 incorporated into a notebook personal computer main body 51. The printed board assembling member 57 and the printed board assembling member 82 both have a printed board 60. In the printed board assembling member 57, a MODEM module-connector assembling member 61 is attached to the printed board 60. In the printed board assembling member 82, a LAN module-connector assembling member 83 is attached to the printed board.
