Patent ID: 8556400

Claim:
An ink for ink jet recording comprising: water; at least one compound selected from the group consisting of 2,4,7,9-tetramethyl-5-decyne-4,7-diol, 3,6-dimethyl-4-octyne-3,6-diol, an alkylene oxide adduct of 2,4,7,9-tetramethyl-5-decyne-4,7-diol, and an alkylene oxide adduct of 3,6-dimethyl-4-octyne-3,6-diol, said compound being present in the ink in an amount of no less than 0.05% by weight and no more than 1% by weight; and a pigment dispersed by using a polymer which is obtained by polymerizing at least 50% by weight or more of benzyl acrylate and/or cyclohexyl acrylate and 15% by weight or less of (meth)acrylic acid as components of the polymer and has an acid value of no less than 50 mgKOH/g and no more than 120 mgKOH/g and a weight average molecular weight of no less than 20000 and no more than 120000 such that the polymer provides the ink with the capability of forming print on gloss paper having a glossiness value at 20° of at least 27.8%.
