Photographically useful organic compounds containing secondary-branched alkyl radicals with at least 15 C atoms corresponding to formula I have a low melting point, good solubility in oil formers and a low tendency towards crystallization which makes them particularly suitable for photographic applications. [Figure] (I) In formula I: PNOV is the residue of a photographically useful organic compound, for example a coupler or oil former; L is a chemical bond or a link between PNOV and X; X represents －O－, －S－, －SO－, －SO2－, －NH－, －NR－(R〓alkyl or acyl), －CO－or alkylidene; R1 and R2 are unbranched alkyl radicals containing at least 6 C atoms, with the proviso that R1 and R2 together contain at least 14 C atoms and, where X represents －CO－or －CH2, at least 17 C atoms.
