Photosensitive compsn. which becomes sticky on exposure to light comprises (a) a salt of a diazonium cpd. of formula (I) and (b) a salt of an aromatic diazonium cpd. having no-OHgp. directly bonding to a benzene ring. In (I) R1 and R2 are each H, (H3,-OCH3, or- NR3R4(but not both R1 and R2 as-MR3R4 at the same time), where R3R4 at the same time), where R3 and R4 are each linear lower alkyl gps.
