One embodiment relates to a water-based ink for an inkjet containing a pigment, a fixing resin, an organic solvent and water, wherein the fixing resin includes an A-B block polymer having an A block and a B block, the A block contains a structural unit (P-1) having an anionic functional group, and the acid value of the A-B block polymer is from 5 to 80 mgKOH/g.

Water-based ink for inkjet and method for producing printed matter

A water-based ink-jet which at least contains a pigment, a water-soluble organic solvent, and a surfactant (A), wherein the water-soluble organic solvent is a water-soluble organic solvent having an HLB value determined by Griffin's method of 8 or less, the water-soluble organic solvent being contained in an amount of 10-50 wt % with respect to the total weight of the water based ink-jet ink, and the surfactant (A) comprises an acetylenediol-based surfactant (a1) having an HLD value determined by Griffin's method of 3 or less.

Provided is an inkjet pigment ink which contains a pigment that is selected from the group consisting of C.L. Pigment Yellow 74 having a transmittance of 70% or more, C.I. Pigment Red 269 having a transmittance of 70% or more, C.I. Pigment Red 122 having a transmittance of less than 70% and C.I. Pigment Yellow 150; a water-soluble solvent that is selected from the group consisting of glycol ethers and diols; water; and a pigment dispersing resin that is a copolymer which contains a monomer A, a monomer B and a monomer C as unit components. The monomer A is an alkyl (meth)acrylate ester; the monomer B is styrene, &#x3b1;-methyl styrene or benzyl (meth)acrylate; and the monomer C is (meth)acrylic acid.

Inkjet pigment ink

An aqueous inkjet ink composition comprising a pigment, a pigment-dispersing resin, resin fine particles (A), water, and hydrophilic solvents (B), the resin fine particles (A) being formed by emulsion polymerizing ethylenically unsaturated monomers including: 20% to 80% by weight of an aromatic ethylenically unsaturated monomer (C) that does not have an ionic functional group; 0.6% to 6% by weight of water-soluble ethylenically unsaturated monomers (F) consisting of 0.5% to 3% by weight of a sulfonic acid group-containing ethylenically unsaturated monomer (D) and 0.1% to 3% by weight of a nonionic water-soluble ethylenically unsaturated monomer (E); and 0.1% to 10% by weight of a crosslinkable ethylenically unsaturated monomer (G), and the hydrophilic solvents (B) including a glycol-based solvent (H) and an ethylene glycol ether-based solvent (I) is provided.

Aqueous inkjet ink composition

An aqueous dispersion of an aqueous polyurethane having an ionic functional group, polyoxyethylene units and terminal hydrazine functional groups is provided. Content of the ionic functional group is about 5 to about 180 milliequivalent per 100 g of the aqueous polyurethane, and content of the polyoxyethylene unit is about 20% by weight or less of a weight of the aqueous polyurethane. The aqueous dispersion is used for a composition for ink, coating or adhesive. Storage stability, water resistance, pigment dispersibility, and adhesion to various kinds of substrates, particularly non-polar substrates, of the aqueous dispersion and the composition are excellent.

Four channels of group 3 facsimile signal are transmitted through a digital transmission line of Bearer rate 64 Kbits/s for a speech signal. A facsimile signal is separated into a tone signal, a binary control signal, and a picture signal, each converted to digital form. Then, a block having 160 bits is assembled including 96 data bits and some control bits, and a justification bit. A justification bit matches clock rate of the present system with clock rate of an external digital transmission line by deleting or inserting one bit in a block. Thus, a conventional group 3 facsimile device is coupled with 16 Kbits/s digital transmission line with no design change for the facsimile device itself.
