Reaction solution for ink jet recording and ink jet recording method using the same
First Claim
1. A reaction solution for an ink jet recording method wherein droplets of an ink composition and droplets of a reaction solution, which produces an agglomerate upon contact with the ink composition, are ejected and deposited onto a recording medium to perform printing,the reaction solution comprising a polyvalent metal salt, ammonia, and benzotriazole or a benzotriazole derivative.

Abstract
Disclosed is a reaction solution for an ink jet recording method wherein droplets of an ink composition and droplets of a reaction solution, which produces an agglomerate upon contact with the ink composition, are ejected and deposited onto a recording medium to perform printing. The reaction solution can realize good print quality and possesses excellent storage stability and ejection stability. Specifically, it has been found that use of a reaction solution comprising at least a polyvalent metal salt, ammonia, and benzotriazole or a benzotriazole derivative in an ink jet recording method, wherein two liquids are printed, can realized good print quality and that the reaction solution possesses excellent storage stability and ejection stability. Further, it has been found that this reaction solution does not attack a nozzle plate having thereon a eutectoid plating and enables stable printing for a long period of time. Thus, the reaction solution of the present invention comprises at least a polyvalent metal salt, ammonia, and benzotriazole or a benzotriazole derivative.

19. A reaction solution consisting essentially of components that allow stable ejection of the reaction solution from an ink jet nozzle and that collectively produce an agglomerate upon contact of the reactant solution with an ink composition comprising a dispersed colorant, said components comprising a polyvalent metal salt, ammonia and benzotriazole or a benzotriazole derivative, said polyvalent metal salt being present in the reaction solution in an amount of about 0.1 to 40% by weight and the ammonia and benzotriazole or benzotriazole derivative being present in the reaction solution in respective amounts such that the reaction solution has a storage stability, ejection stability or both that is improved as compared with the reaction solution without the ammonia or the benzotriazole or benzotriazole derivative.
