摘要： PROBLEM TO BE SOLVED: To incorporate moistureproofing and rustproofing abilities and to make recyclable by laminating a moistureproof paper having a moistureproofing agent layer including water disaggregation and a base material layer, a waterproof paper having water resistance and a rustproof paper having rustproofing ability. SOLUTION: A moistureproofing paper 4, two water resistant papers 6, 8 and a rustproofing paper 10 are sequentially laminated in this order in such a manner that the paper 4 and the paper 6 are adhered through an adhesive layer 5 and the paper 6, 8 are similarly adhered through an adhesive layer 7. The paper 8 and the paper 10 are also adhered through an adhesive layer 9. The paper 4 is formed in a structure in which a moistureproofing agent layer 2 is laminated on a surface of a base material layer 3. As a water disaggregative moisture proofing agent of the layer 2, a wax emulsion, a resin emulsion, a latex or the like is use. As the paper 6, 8, particularly paper tube raw paper is optimum. As the paper 10, neutral kraft paper is suitable, and as its rustproofing agent, alkali salt or the like of each type organic acid, a sulfur compound, an ester or the like, an alkylsulfonate or the like is used. As the adhesive, for example, an adhesive of a vinyl acetate is suitable for recycling.

摘要： PROBLEM TO BE SOLVED: To provide a transfer image receiving medium for an ink jet printer having excellent sheet feedability and blocking preventiveness without impairing heat sealability and transparency. SOLUTION: The transfer image receiving medium for an ink jet printer comprises a support layer 1, a release layer 2, an ultraviolet cutting layer 3 and an image receptive layer 4 sequentially laminated. The layer 4 is obtained by adding a thermoplastic resin beads each having a mean particle size of 10 to 150 μm melted or softened at a transfer temperature to a thermoplastic matrix resin having heat sealability. The beads are made of a urethane resin having a melting point of 90 to 120 deg.C, and the beads 5 having a mean particle size of 10 to 150 μm are preferable.

摘要： PROBLEM TO BE SOLVED: To provide a laminated bag in which its stored content is not seen at first, but as required its stored content can be easily acknowledged. SOLUTION: This laminated bag is constituted of a front surface sheet 5 and a rear surface sheet 11. The front surface sheet 5 is constituted of a front surface paper layer 1 and a front surface laminate layer 3. A part between the front surface paper layer 1 and the front surface laminate layer 3 is applied as a pseudo-adhered state. The rear surface sheet 11 is constituted by the rear surface paper layer 7 and the rear surface laminate layer 9. The front surface sheet 5 and the rear surface sheet 11 are of rectangular shape having the same size, they are adhered to each other at the portions corresponding to three sides, thereby the sheets are formed into a bag. A slit 13 is formed at the front surface paper layer 1, the front surface paper layer 1 is peeled off from the front surface laminate layer 3 at the slit 3 to form a small window 15.

摘要： PROBLEM TO BE SOLVED: To provide a printing paper, the elasticity and deformation of which are remarkably reduced even when this printing paper is employed in an ink jet printer, in which a water-base ink is employed, or in a laser printer, in which heating is performed for fixing. SOLUTION: Cellulose fibers of this low elastic printing paper are at least partially covered with a gel, which is obtained by means of a sol-gel method from a hydrolyzable silane or from its partial hydrolyzate. The covering of the cellulose fibers is performed through the paper making method in a sol solution including the dydrolyzable silane or its partial hydrolyzate or through the coating or impregnation of the sol solution on or in the printing paper.
