Abstract
1463216 Pigment pastes BAYER AG 14 Feb 1975 [16 Feb 1974] 6286/75 Heading C4A [Also in Division C3] A pigment paste contains 3-74% wt. of an organic or inorganic pigment, 6-50% wt. of a polyurethane resin and 20-90% wt. of an organic diluent, in which the polyurethane resin used is a reaction product of at least one aromatic diisocyanate with at least one C 2 -C 10 polyol and at least one C 6 -C 8 mono-alcohol, optionally mixed with shorter- or longer-chain monoalcohols or ethylene glycol monoethers, the percentages being based on the total weight of pigment paste. Preferred polyols are C 5 -C 8 diols and/or trimethylolpropane. The monoalcohols may be aliphatic, cycloaliphatic or aromatic. The monoalcohol may be benzyl alcohol or phenoxyethanol. The resins preferably have a melting range of 80-120‹ C. and a viscosity of 10-120 cp. at 25‹ C. measured as a 40% wt. solution in ethylene glycol monomethyl ether acetate. Thickeners, e.g. silica and montmorillonites, and fillers, such as kaolin, talc or blanc fixe can be added to the pigment paste. Suitable solvents include those which are free of OH groups, e.g. alkyl and/or aryl esters of di- or poly-basic acids, e.g. adipic, phthalic or phosphoric acid; esters of aromatic or aliphatic monocarboxylic acids with polyols, e.g. glycerol triacetate, esters, ketones and aromatic hydrocarbons. Other solvents include OH-containing esters or ethers. Suitable pigments are those of the azo, anthraquinone, azaporphine, thioindigo, quinacridone, dioxazine, naphthalenetetracarboxylic acid, perylenetetracarboxylic acid or isoindolinone series; metal complex pigments or dyestuff lakes, zinc sulphides, cadmium sulphides and selenides, ultramarine, titanium dioxides, iron oxides, nickel- or chromiumantimony-titanium-oxides, cobalt blue, chromium oxides, chromates and carbon black. In the examples pigment pastes are prepared using as the polyurethane resin: either (1) the reaction product of 2,4- and 2,6-tolylene diisocyanate (80/20 mixture), trimethylolpropane and either (A) n-octanol, or (B) 1-methylcyclohexanol and 2-ethylhexanediol, or (C) glycol monoethyl ether and n-octanol; or (2) the reaction product of 2,4- and 2,6-tolylene diisocyanate (65/35 mixture), cyclohexanol and 2,2-dimethyl-1,3-proanediol; as the pigment :- carbon black, rutile titanium dioxide or copper phthalocyanine, and as solvent:- tributoxyethylphosphate; a branched polyether of M.Wt. 4800; diphenyl 2-ethylhexylphosphate; tributylphosphate. The pigment pastes can be used to colour ether-based or ester-based polyurethane foams or one component lacquers with NCO groups.
