Claims
- 1. A color concentrate, suitable for dispersion in a synthetic resin for coloring the same, said concentrate comprising a colorant dispersed in a polymer as a binder for said colorant, said polymer consisting essentially of
- (a) 70-90 percent, by weight of the polymer, of methyl methacrylate,
- (b) 10-20 percent, by weight of the polymer, of methyl acrylate, and
- (c) at least 0.1 percent, by weight of the polymer, of at least one free radically polymerizable monomer of the formula ##STR5## wherein R.sub.1 is hydrogen or methyl and R.sub.2 is a member selected from the group consisting of
- (i) --NR.sub.3 R.sub.4, wherein R.sub.3 and R.sub.4, taken alone, are the same or different and are hydrogen or linear or branched alkyl having 1 to 5 carbon atoms, and R.sub.3 and R.sub.4, taken together with the nitrogen atom to which they are bonded, form a 5- or 6-membered heterocycle or such a heterocycle containing further nitrogen or oxygen atoms, and
- (ii) --Y--X--NR.sub.3 R.sub.4, wherein Y is oxygen or --NR.sub.5 --, X is linear or branched alkylene having 2 to 10 carbon atoms or is cycloalkylene, and R.sub.5 is hydrogen or alkyl having 1 to 6 carbon atoms.
- 2. A polymer, suitable as a binder in the formulation of color concentrates, consisting essentially of
- (a) 70-90 percent, by weight of the polymer, of methyl methacrylate,
- (b) 10-20 percent, by weight of the polymer, of methyl acrylate, and
- (c) at least 0.1 percent, by weight of the polymer, of at least one free radically polymerizable monomer of the formula ##STR6## wherein R.sub.1 is hydrogen or methyl and R.sub.2 is a member selected from the group consisting of
- (i) --NR.sub.3 NR.sub.4, wherein R.sub.3 and R.sub.4, taken alone, are the same or different and are hydrogen or linear or branched alkyl having 1 to 5 carbon atoms, and R.sub.3 and R.sub.4, taken together with the nitrogen atom to which they are bonded, form a 5- or 6-membered heterocycle or such a heterocycle containing further nitrogen or oxygen atoms, and
- (ii) --Y--X--NR.sub.3 R.sub.4, wherein Y is oxygen or --NR.sub.5 --, X is linear or branched alkylene having 2 to 10 carbon atoms or is cycloalkylene, and R.sub.5 is hydrogen or alkyl having 1 to 6 carbon atoms.
- 3. A color concentrate as in claim 1 wherein component (c) is (c) (i).
- 4. A color concentrate as in claim 8 wherein Y is oxygen.
- 5. A color concentrate as in claim 3 wherein X is alkylene having two or three carbon atoms.
- 6. A color concentrate as in claim 3 wherein X is branched alkylene having a tertiary carbon atom.
- 7. A color concentrate as in claim 3 wherein X is 2,2-dimethylpropyl.
- 8. A color concentrate as in claim 1 wherein component (c) is (c) (iv).
- 9. A color concentrate as in claim 8 wherein Y is oxygen.
- 10. A color concentrate as in claim 8 wherein X is alkylene having two or three carbon atoms.
- 11. A color concentrate as in claim 8 wherein X is branched alkylene having a tertiary carbon atom.
- 12. A color concentrate as in claim 8 wherein X is 2,2-dimethylpropyl.
- 13. A color concentrate as in claim 1 wherein the ratio by weight of component (a) to component (b) is from 6:1 to 3.3:1.
- 14. A color concentrate as in claim 1 wherein the ratio by weight between the components (a), (b), and (c) is 4.2.+-.0.7:1:0.3.+-.0.2.
- 15. A color concentrate as in claim 1 wherein component (c) is present in an amount from 1 to 6 percent by weight of the polymer.
- 16. A polymer as in claim 2 comprising at least one percent by weight of component (c).
