Colored fine particulate resins can each be produced by bringing a colored resin, which comprises a thermally fusible resin and a colorant evenly distributed in the thermally fusible resin, into a molten state; forming the colored resin, which is in the molten state, into droplet-shaped fine particles in a non-dissolving medium which does not dissolve the colored resin; and then cooling and solidifying the droplet-shaped fine particles. The colored fine particulate resins are useful in image recording materials, printing materials and paints. Articles can be colored with the image recording materials, printing materials or paints.
