Abstract: An inkjet recording method for printing an inkjet recording medium comprising an ink-receiving layer containing inorganic pigment, starch and copolymer latex on a surface of a base with inkjet ink as aqueous pigment ink, a content of the inorganic pigment being 10 g/m2 or more to 35 g/m2 or less in the ink-receiving layer, and a content of calcium carbonate being from 80% by weight or more to 100% by weight or less, the inkjet ink containing one or more selected from self dispersed pigment and pigment containing water-insoluble polymer particles, from 10% by weight or more to 48% by weight or less of a water-soluble organic solvent A having a boiling point of 230° C. or less, from 0% by weight or more to 5.0% by weight or less of a water-soluble organic solvent B having a boiling point of 280° C. or more, from 42% by weight or more to 70% by weight or less of water.

Abstract: Provided are an ink composition usable in a solar battery manufacturing process, a method of forming a pattern using the ink composition, an insulation film formed of the ink composition, and an etching mask formed of the ink composition. The ink composition includes: a) a polymerizable compound having an ethylenically unsaturated bond; b) a fluorinated surfactant; and c) a solvent, wherein the ink composition has a solid content of 45 parts by weight to 99.99 parts by weight.

Abstract: Inkjet ink contains water, hydrosoluble organic materials; and a colorant, wherein the hydrosoluble organic materials account for 30% by weight to 50% by weight of the inkjet ink, wherein the hydrosoluble organic materials contain 3-methoxy-1-butanol, herein the hydrosoluble organic materials contain at least one of 1,3-butane diol, 3-methyl-1,3-butane diol, 1,2-butane diol, 2,3-butane diol, 1,2-pentane diol, 3-methyl-3-hydroxymethyl oxetane, 1,2-propane diol, or 1,3-propane diol in an amount of 1% of the inkjet ink.

Abstract: A masking material and method of forming a masking tape that includes a substrate and an adhesive layer disposed on the substrate. The adhesive layer is preferably thicker than the substrate and formed of a material that has a modulus of elasticity combined with a viscoelastic component that allows the adhesive to conform to discontinuities associated with a surface to which the masking material is applied. Preferably, the adhesive is formed in two rows that are aligned with the lateral edges of the substrate and which prevent seepage of liquid materials between the masking material and the surface to which it is applied.
