Patent ID: 8735467

Claim:
A process for producing a pigment-containing curable resin solution composition which comprises a pigment and a modified polysiloxane, the process comprising the steps of: (a) preparing a pigment-dispersed liquid, wherein a pigment is dispersed in a dispersion medium consisting essentially of an organic solvent and a first modified polysiloxane dissolved in the organic solvent; and (b) mixing the pigment-dispersed liquid with a resin solution which comprises at least a second modified polysiloxane, wherein the pigment-dispersed liquid exhibits a change of rotational viscosity within −2% to +2% after storage of thirty days at 25° C. based on a rotational viscosity after storage of one day at 25° C., and exhibits no occurrence of aggregation after storage of one day and seven days at 25° C. when observed by a microscope with magnifying ink 40 times.
