Abstract
Abstract The present invention relates to an ink applying method for obtaining desired sharp patterns while preventing bleeding and an ink composition therefor, in applying a low viscosity liquid to a polymer product such as fabric in the form of droplets according to the ink jet or spray process. As a treating solution there is used a solution incorporating a water-soluble or water-dispersible material which contains -OS0 3 M group or -S0 3 M group as a hydrophilic group in which M is a monovalent metal, ammonium or amine, and a fiber structure is pretreated with a chemical for coagulating the said hydrophilic group, whereby good bleeding preventing effect and deep shading effect even against markedly bleeding fiber structures such as thin fabrics as well as level dyeing effect of colored portions can be attained without impairing the injection characteristic. Sharp patterns equal or superior to conventional prints can be obtained.
