Patent ID: 8557922

Claim:
Diamine compound of formula (I): wherein, A represents an unsubstituted or substituted carbocyclic or heterocyclic aromatic group selected from a monocyclic ring of five or six atoms, two adjacent monocyclic rings of five or six atoms, a bicyclic ring system of eight, nine or ten atoms, or a tricyclic ring system of thirteen or fourteen atoms; and wherein the following compound residue of formula (I), the compound of formula (Ia) represents a straight-chain or branched C 1 -C 16 fluoroalkyl group, wherein F is fluorine, and x 1 is an integer from 0, to 15, B represents a straight-chain or branched C 1 -C 16 alkyl group, which is unsubstituted or substituent(s) substituted by di-(C 1 -C 16 alkyl)amino, C 1 -C 6 alkyloxy, nitro, cyano and/or chlorine; and wherein one or more —CH 2 — group may independently from each other be replaced by a linking group; D represents an unsubstituted or substituted, aliphatic, aromatic and/or alicyclic diamine group having from 1 to 40 carbon atoms, E represents an aromatic group, an oxygen atom, a sulphur atom, —NH—, —N(C 1 -C 6 alkyl)—, —CR 2 R 3 , wherein R 2 and R 3 are independently from each other hydrogen or a cyclic, straight-chain or branched, substituted or unsubstituted C 1 -C 24 alkyl, wherein one or more —CH 2 — group(s) may be independently from each other replaced by a linking group, and with the proviso that at least one of R 2 and R 3 is not hydrogen; S 1 , S 2 each independently from each other represents a spacer unit; X, Y each independently from each other represents hydrogen, fluorine, chlorine, cyano, unsubstituted or with fluorine substituted C 1 -C 12 alkyl, in which one or more —CH 2 — groups may be replaced by a linking group; n, n1 each independently from each other represents 1, 2, 3 or 4, with the proviso that if n is 2, 3, or 4, each A, B, x 1 , D, E, S 1 , S 2 , X, Y are identical or different; and if n1 is 2, 3 or 4 each B, x 1 is identical or different.
