This invention relates to a method for for the production of a halogen-containing phthalocyaline compound by the cyclization of phthalonitrile compounds either singly or in combination with a metal compound, characterized in effecting the cyclization in an organic compound having a hydroxyl group and/or a carboxylic acid in an amount in the range of 0.01-10 mass parts per one mass part of the phthalonitrile compounds while continuing the introduction of an inert gas. This method, by using a solvent capable of serving as a specific oxygen source destined to participate in the reaction of complexing a metal compound introduced into a phthalocyanine dye, permits the production of a phthalocyanine compound inexpensively in a high yield.
Treatment of terminal olefinsbearingelectron-withdrawing groups with (R,R)-pentane-2,4-diol (2) in the presence of PdCl2–CuCl–O2 in 1,2-dimethoxyethane gives cyclic acetals such as (3) and (12b)via attack at the terminal carbon atom; the corresponding acetals are similarly formed from propane-1,3-diol (5) and ethylene glycol (8).

Provided is an ultraviolet-light curable inkjet ink and an inkjet image formation method that uses said inkjet ink, The inkjet ink can be discharged from an inkjet head without being diluted by a solvent, has high photocuring sensitivity and produces high quality images with excellent weather resistance (smear resistance). The inkjet ink is characterised by a polymer compound that contains a compound selected from a chiral group containing maleimide compound, a vinyl ether compound and an N-vinyl compound, in an ultraviolet-light curable inkjet ink that contains at least the polymer compound.
