Abstract:
1. A composition comprising from 92 to 97% by weight organic pigment and from 3 to 8% by weight binder, in each case based on the composition, wherein the binder is a mixture consisting of from 5 to 60% by weight, based on the binder, of modified cellulose wherein, on average, per glucose unit, from 0.5 to 1.4 hydroxyl hydrogen atoms are replaced by R from 40 to 95% by weight, based on the binder, of a compound of formula and from 0 to 20% by weight of further substances; wherein Q is a hydrocarbon radical containing from 12 to 24 carbon atoms, unsubstituted or mono- to tri-substituted by hydroxy or OR 1 , each R 1 , independently of any other R 1 , is unsubstituted C 1 -C 4 alkyl or unsubstituted C 1 -C 4 alkylcarbonyl, each R 2 , independently of any other R 2 , is an organic group different from R 1 and consisting of 2 to 10 carbon, from 0 to 4 oxygen and from 0 to 2 nitrogen atoms, and R 3 and R 4 are each independently of the other hydrogen, R 1 , R 2 , C 5 -C 8 alkyl, C 5 -C 8 alkylcarbonyl, C 5 -C 8 alkenyl, C 5 -C 8 alkenylcarbonyl, C 5 -C 8 cycloalkyl, C 5 -C 8 cycloalkylcarbonyl, C 5 -C 8 cycloalkenyl, C 5 -C 8 cycloalkenylcarbonyl, phenyl, benzoyl, tolyl, methylbenzoyl, benzyl, phenylacetyl, phenethyl or styryl.
