摘要: An ink jet print head in which a portion along which both piezoelectric conversion elements and a nozzle forming member are adhesively fixed is positioned at least a distance exceeding that of a stress concentration region toward a base portion of the piezoelectric conversion elements from a vibrating fulcrum of the piezoelectric conversion elements. As a result, any thermally induced stress concentration in the piezoelectric conversion elements is diffused over the adhesively fixed stress that acts backward of such stress concentration region. This prevents each piezoelectric conversion element from being deformed, thereby contributing to eliminating variations in the nozzle gap.

摘要: An ink composition for ink jet recording comprising a dye, 1 to 10% by weight of glycerin, 1 to 5% by weight of a monohydric alcohol having 4 or less carbon atoms, 0.5 to 10% by weight of 1,3-dimethyl-2-imidazolidinone and 75 to 95% by weight of water. The ink composition of the present invention can offer a good balance of properties required of the ink jet recording ink, especially quality of the print, dryability of the print, water-resistance of the print, storage stability and a property that does not attack members constituting a recording head and an ink passage.
