Abstract:
The invention relates to the use of liquid colouring preparations, containing at least one pigment and 0.5 to 10 wt.% of at least one dye, based on the pigment, for the decorative colouring of derived timber products.
Abstract:
Disclosed are black perylene pigments containing one of the isomers of formula (Ia) or (Ib), wherein the variables have the following meaning: R , R independently represent phenylene, naphthylene, or pyridylene, each of which can be monosubstituted or polysubstituted by C1-C12 alkyl, C1-C6 alkoxy, hydroxy, nitro, and/or halogen; X represents halogen; n represents 0 to 4. The inventive black perylene pigments alternatively contain a mixture of both isomers and are provided with a black number >= 210 in an alkyd/melamine baking enamel.

Abstract:
A pigment preparation contains: (A) at least 1 finely divided organic or inorganic pigment, (B) a dispersion medium based on arylsulfonic acid-formaldehyde-condensation product or oxalkylated phenols, (C) an alcoholic acrylic resin, (D) an inorganic or organic base, and (E) water is new. An Independent claim is included for a process for printing laminar or 2-dimensional substrates by ink-jet printing with the preparation.
Abstract:
Use of liquid colorant formulations containing pigment(s) (I) and 0.5-10 wt.% dye(s), with respect to (I), for decorative coloring of wood materials is claimed. An Independent claim is also included for wood materials colored with this formulations.
