Abstract:
PROBLEM TO BE SOLVED: To easily obtain a novel chemical agent for marking well penetrating into a wood and to generate marked color reaction by an extremely small amt. of the marking substance to enable visual observation, by treating the wood with arylamine represented by a specific formula. SOLUTION: In a wood marking method, wood is treated with arylamine represented by formula I, wherein Ar is a group represented by formula II, R and R are mutually unrelated hydrogen, a C1 -C18 alkyl group which may be substituted, may be interrupted in a form of an ether functional group by 1-3 oxygen atoms or interrupted by 1-3 non-adjacent C1 -C4 alkylimino groups, C5 -C7 cycloalkyl, C3 -C18 alkenyl or phenyl which may be substituted, or R and R are a 5- or 6-membered saturated heterocylic group together with a nitrogen atom.
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:

Abstract:
Use of solid pigment preparation (I) comprising at least a pigment (30-90 wt.%) (A) and at least a water-soluble surface-active additive (10-70 wt.%) (B), for coloring cellulose/polymer composite materials. Independent claims are also included for: (1) a preparation of colored cellulose/polymer composite materials comprising coloring cellulose particles with (I); and (2) a cellulose/polymer composite materials, which are colored with (I).
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.
Abstract:
Light-colored engineered wood boards produced from wood fibers that are bleached and dyed with liquid dye preparations, where the preparation comprises at least one pigment and at least one dye that absorbs light in the visible range of the electromagnetic spectrum. An independent claim is included for furnishings comprising the boards.
Abstract:
Use of liquid coloring agent preparation (I) comprising at least one pigment and at least one dye, for the coloring of cellulose/polymer composite materials. Independent claims are also included for: (1) the preparation of colored cellulose/polymer composite materials comprising using cellulose particles, which were dyed with (I); and (2) a cellulose/polymer composite materials, which are dyed with (I).
