Abstract
Novel tetrabenzodiazadiketoperylene dyes and pigment and methods of coloring polymer compositions are described.
Claims11
A tetrabenzodiazadiketoperylene of formula I
- wherein
- X, Y, Z and G independently of each other are
- C1-12 alkyl, C3-6 cycloalkyl, C7-12 aralkyl, C6-10 aryl, C3-9 saturated or unsaturated heterocycle, halogen, —OR, CF3, —COOR,—CONR′R, NO2, NR′R, SO3H or SO2NR′R;
- R and R′, independently of each other are hydrogen, C1-8 alkyl, C3-6 cycloalkyl, C6-10 aromatic or C7-12 aralkyl;
- m, n, o and p are independently 0, 1, 2, 3 or 4, and when m, n, o or p is 2, 3 or 4, each X, Y, Z or G substituent may each be a different group as defined above
- with the proviso that at least one of m, n, o and p are 1, 2, 3 or 4.

- R and R′, independently of each other are hydrogen, C1-8 alkyl, C3-6 cycloalkyl, C6-10 aromatic or C7-12 aralkyl;
- m, n, o and p are independently 0, 1, 2, 3 or 4, and when m, n, o or p is 2, 3 or 4, each X, Y, Z or G substituent may each be a different group as defined above
- with the proviso that at least one of m, n, o and p are 1, 2, 3 or 4.
