An organic secondary battery comprising an anode including an anode-active material, a cathode including a cathode-active material and an electrolytic medium, in which at least the cathode-active material consists essentially of a benzene polymer, and a method of producing the benzene polymer by electrolytic polymerization with anodic oxidation of a benzene or benzene derivative monomer in an electrolytic solution.

Organic secondary battery

A photo-sensitive and heat-sensitive composition consisting essentially of (a) a photooxidant, (b) a color-generator generating color when oxidized, (c) an acid promoting said color generation, (d) a cobalt (III) complex, (e) a photoreductant, (f) a hydrogen donator and (g) a chelating agent consisting of a dioxime compound having the general formula: ##STR1## (where n is an integer of 0 to 3, and R.sub.1 and R.sub.2 can each represent an alkyl, aryl or aralkyl group), and a recording element using the same.

Photo-sensitive and heat-sensitive composition and recording element

A photo-sensitive and heat-sensitive composition consisting essentially of (a) a photooxidant, (b) a color-generator generating color when oxidized, (c) an acid promoting said color generation, (d) a cobalt (III) ammine and/or amine complex, (e) a photoreductant, (f) a hydrogen donator, (g) at least one kind of chelating agent selected from dioxime chelating agents having the general formula (I): ##STR1## (wherein n is an integer of 0 to 3, and R.sub.1 and R.sub.2 can each represent an alkyl, aryl or aralkyl group) and diantipyrylmethane chelating agents having the general formula (II): ##STR2## (wherein R.sub.3, R.sub.4, R.sub.5, R.sub.3 ', R.sub.4 ' and R.sub.5 ' can each represent a hydrogen atom and an alkyl or aryl group, and R.sub.6 and R.sub.7 can each represent a hydrogen atom and an alkyl, substituted or nonsubstituted aryl or aralkyl group), and (h) at least one kind of stabilizer selected from noble metal complexes, organic oxidants and organic acids, and a recording element using the same.
