Abstract

1,258,924. Esterified hydroquinone compounds. AGFA GEVAERT. 22 May, 1969 [10 June, 1968], No. 27524/68. Heading C2C. [Also n Division G2] The invention comprises a hydroquinone silver halide developing agent precursor wherein at least one of the hydroxy groups of the hydroquinone has been esterified to form a hydrolysable aliphatic acyloxy radical comprising a quaternary ammonium group. The compounds may be prepared by reaction of the corresponding haloacyl esters with a compound containing a tertiary amine group.
