  A process for the conversion of aromatic compounds to dialkylbenzene compounds rich in the 1,4-dialkylbenzene isomer. The reaction is carried out in the presence of a particu- lartype of zeolite catalyst having a silica to alumina mole ratio of at least 12 and a constraint index of about 1-12, said catalyst having been modified by treatment with compounds of the alkaline-earth metals (Ca, Sr, Ba), and optionally phosphorus, to deposit a minor proportion of such elements on the zeolite.

  Provided are an ink high in fixability of image, water resistance and solvent resistance though it is a liquid ink containing water as a solvent and a quick-drying ink jet printer which uses said ink. The liquid ink of the present invention is a liquid ink used for ink jet printers which contains a binder, a colorant and a solvent, characterized in that it contains at least 10% by weight of water and the binder comprises a polyamic acid salt or at least one species of photo-curable resin. The ink jet printer is characterized by being provided with a device for fixing the image formed on a paper by heating or light irradiation. Although water is used as the solvent, the image can be more rapidly fixed as compared with air-drying of the image and, besides, there are no risks of fire caused by ignition. Thus, the ink jet printer of the present invention is useful for use in offices.

  本发明提供了一种虽然是含水作为溶剂的液体墨水，但具有高图像固定性、耐水性和耐溶剂性的墨水，以及使用所述墨水的快干喷墨打印机。本发明的液体墨水是一种用于喷墨打印机的液体墨水，它含有粘合剂、着色剂和溶剂，其特征在于，按重量计，它至少含有 10%的水，粘合剂包括聚酰胺酸盐或至少一种光固化树脂。喷墨打印机的特点是配有一个装置，用于通过加热或光照射固定在纸上形成的图像。虽然使用水作为溶剂，但与风干图像相比，可以更快地固定图像，而且没有因点火而引起火灾的危险。因此，本发明的喷墨打印机适用于办公室。
