| 摘要 |
The present invention relates to a photographic element comprising in a hydrophilic colloid layer a ballasted compound comprising a ballasting moiety that renders such compound fast to diffusion in said hydrophilic colloid layer and a photographically useful moiety linked to this ballasting moiety, the ballasting moiety corresponding to the general formula: <CHEM> wherein A is hydrogen, C1-C20 alkyl, or aryl; R is C1-C20 alkyl; R<1> is hydrogen, hydroxy, sulpho, carboxy, cyano, a halogen atom, trifluoromethyl, hydroxyalkyl, sulphoalkyl, carboxyalkyl, alkyl, alkoxy, alkylthio, acyl, R<2>CONH- , R<2>NHCO- , R<2>NHSO2 , or R<2>SO2N(R<3>)- , each of R<2> and R<3> being hydrogen, C1-C5 alkyl, or aryl and when both present having a same or a different significance. The present invention also relates to compounds comprising such ballasting moiety.
