Abstract
The present invention relates to an aqueous ink jet recording liquid of a pigment type, which liquid has excellent stability and printing characteristics; and also to a process for the preparation of said liquid. The ink jet recording liquid of the present invention is obtained by dispersing a pigment and a resin in an aqueous medium. Said resin is an aqueous dispersion-type resin comprising a shell composed of a polymer having a glass transition point in the range of 50.degree. C. to 150.degree. C. and a core composed of a polymer having a glass transition point in the range of -100.degree. C. to 40.degree. C.
