Reaction solution for ink-jet recording, and ink-jet recording method using the solution

摘要

A reaction solution that is used for image recording with an ink containing a coloring material in a dissolved or dispersed state to destabilize the dissolved or dispersed state of the coloring material in the ink in contact with the ink to provide high quality and abrasion-resistant images, wherein the reaction solution contains at least a polyvalent metal ion and a nonionic polymer, the Ka value according to the Bristow method is from 1.3 mL.m<-2>.msec<-1/2> to 3.0 mL.m<-2>.msec<-1/2> inclusive, and the viscosity is from 20 mPa.s to 150 mPa.s inclusive.
