Document Type and Number:
WIPO Patent Application WO/2010/031860
Kind Code:
A3
Abstract:
A dye for a fluid of an electrowetting element, the dye having a general formula selected from the group consisting of: (Formula I, II and III) wherein Q has the general formula: -HetlRl or -HetlRlR2; V has the general formula: -Het2R3 or -Het2R3R4; Hetl and Het2 are heteroatoms; Rl and R3 are H; R2 and R4 are any functional group; T and U are any functional group; W, X, Y and Z are H or an alkyl group; and F, G, L and M are H or an alkyl group, and with the proviso that the dye does not have the general formula: (IV). The present invention further relates to a fluid comprising a dye of the present invention, an electrowetting element and an optical display device comprising the fluid, and a use of the dye to reduce photo-bleaching.
