Novel Pyridone Dyes

Abstract

The invention relates to compounds of the formula (I): in which R0 is C1-C6-alkyl or CF3; R1 is sulfo, carboxyl, C1-C4-alkylenesulfo, C1-C4-alkylenecarboxy, CONH2, CONH(C1-C4-alkyl) or CN, R2 is C1-C18-alkyl, C2-C18-alkenyl, hydroxy-C1-C18-alkyl, or —(C1-C6-alkylene-O—)m—R where R is defined as H, C1-C16-alkyl or hydroxy-C1-C16-alkyl and m is a number from 1 to 20, R3 is H, sulfo, carboxyl, C1-C6-alkyl or C1-C6-alkoxy, R4 is H, C1-C6-alkyl or C1-C6-alkoxy, R5 is OH, OM, C1-C6-alkyl, unsubstituted C6-C10-aryl or C1-C6-alkyl-, halogen-(e.g. F, Cl, Br), carboxyl- or sulfo-substituted where the compounds of the formula (I) contain at least one anionic radical from the group of sulfo and carboxyl having the countercation M+, where M+ is an alkali metal cation or an organic cation. The compounds of the formula (I) are especially suitable for use in color filters.
