PROBLEM TO BE SOLVED: To provide a colored resin composition exhibiting excellent storage stability and exhibiting good water resistance and alkali resistance after curing, and to be more inexpensively colored by an ink jet method using the composition as an ink. Manufacture filters. SOLUTION: A composition comprising a water-soluble vinyl resin obtained by copolymerizing methacryloyloxyethyl isocyanate having blocked isocyanate groups and another vinyl monomer, a crosslinking agent, a colorant and water is prepared. After the composition is applied to a transparent substrate by an ink jet method, a heat treatment is performed to remove the isocyanate group block and crosslink. |
