There is provided a water-based ink for ink-jet recording including: water; a self-dispersible black pigment; and a resin-dispersed pigment of which hue angle is in a range of 180 to 270 and of which sedimentation velocity in the water-based ink is slower than sedimentation velocity of the self-dispersible black pigment in the water-based ink. A ratio (R/S) of a solid content weight (R) of the resin-dispersed pigment to a solid content weight (S) of the self-dispersible black pigment in the water-based ink is in a range of 0.26 to 0.80.

An opaque lightly coloured thermoplastic moulding composition is made having improved long-term weathering stability as well as excellent optical appearance, especially high colour brilliance. The thermoplastic moulding compositions include the combination of an inorganic pigment and an organic soluble dye, wherein the inorganic pigment is selected from specific mixed metal oxides and mixed metal oxosulfides. A process is also made to produce the coloured moulding composition. Colouring compositions, such as masterbatches, which can be used for producing the coloured thermoplastic moulding composition are further developed. Opaque lightly coloured formed articles are finally made from the thermoplastic moulding composition, for example injection moulded articles and extruded articles.
