Patent ID: 7285592

Claim:
A set of colorant preparations comprising at least one colorant preparation in each of the colors black, cyan, magenta, and yellow, wherein at least one of the colorant preparations is an aqueous pigment preparation wherein the aqueous pigment preparation is an organic and/or inorganic pigment dispersed in an acrylate resin solution and a dispersing aid, wherein the acrylate resin is a copolymer consisting essentially of from 50 to 80 mol % of a monoalkenyl aromatic and from 20 to 50 mol % of acrylate and has an average molar mass M v of between 1 000 and 50 000 g/mol, and wherein the dispersing aid is a compound of the formula (I) R—O—(CH 2 —CH 2 —O) m —CH 2 —COOM (I) in which R is a C 10 -C 20 alkyl radical or a C 10 -C 20 alkenyl radical m is a number from 1 to 15, and M is a monovalent cation and wherein the pigment preparation consists essentially of a) from 5 to 50% by weight of the pigment, b) from 0.25 to 20% by weight of the acrylate resin, c) from 1 to 12% by weight of a compound of the formula (I), d) from 5 to 60% by weight of water, e) from 0 to 10% by weight of an organic solvent, f) from 0 to 15% by weight of a hydrotropic substance, and g) from 0 to 10% by weight of at least one additive, based in each case on the total weight of the pigment preparation, wherein the acrylate is a methyl (meth)acrylate, ethyl (meth)acrylate, n-propyl (meth)acrylate, n-butyl (meth)acrylate, isopropyl (meth)acrylate, isobutyl (meth)acrylate, n-amyl (meth)acrylate, n-hexyl (meth)acrylate, isoamyl (meth)acrylate, 2-hydroxyethyl (meth)acrylate, 2-hydroxypropyl (meth)acrylate, N,N-dimethylaminoethyl (meth)acrylate, N,N-diethylaminoethyl (meth)acrylate, t-butylaminoethyl (meth)acrylate, 2-sulfoethyl (meth)acrylate, trifluoroethyl (meth)acrylate, glycidyl (meth)acrylate, benzyl (meth)acrylate, allyl (meth)acrylate, 2-n-butoxyethyl (meth)acrylate, 2-chloroethyl (meth)acrylate, sec-butyl (meth)acrylate, tert-butyl (meth)acrylate, 2-ethylbutyl (meth)acrylate, cinnamyl (meth)acrylate, crotyl (meth)acrylate, cyclohexyl (meth)acrylate, cyclopentyl (meth)acrylate, 2-ethoxyethyl (meth)acrylate, furfuryl (meth)acrylate, hexafluoroisopropyl (meth)acrylate, methallyl (meth)acrylate, 3-methoxybutyl (meth)acrylate, 2-methoxybutyl (meth)acrylate, 2-nitro-2-methylpropyl (meth)acrylate, n-octyl (meth)acrylate, 2-ethylhexyl (meth)acrylate, 2-phenoxyethyl (meth)acrylate, 2-phenylethyl (meth)acrylate, phenyl (meth)acrylate, propargyl (meth)acrylate, tetrahydrofurfuryl (meth)acrylate and tetrahydropyranyl (meth)acrylate, or a combination thereof.
