Abstract

1413610 Developing photo-resists OCE-VAN DER GRINTEN NV 2 Oct 1973 [3 Oct 1972] 45939/73 Heading G2C Imagewise exposed photo-resists in which either the exposed or unexposed areas dissolve in alkali are developing with an aqueous solution containing a lignosulphate and having a pH of 12.5 to 13.5. Specified photo-resists are naphthoquinone diazide esters admixed with novolaks or poly (o-vinylphenol) and optioanlly p-aminobenzoic acid. The developer preferably contains caustic soda, a surfactant, a mono- or poly-hydric alcohol or a hydroxycarboxylic acid or a salt thereof (e.g. citric, tartaric, gallie or gluconic acid or carboxymethyl cellulose).
