  • Patent number: 5466536
    Abstract: A photographic support material has a reverse side layer which includes a polymer having a film formation temperature which does not exceed 70.degree. C., and a conductive material. The polymer may be a mixture of polymers or copolymers of styrene, alkylstyrene, (meth)acrylic acid and (meth)acrylic acid alkylester. The conductive material may be an alkali salt of a crosslinkable polysulfonic or polystyrene sulfonic acid or a coated or uncoated metal oxide from the group of metals of the 2nd to 4th main or sub groups, and may also contain a polyfunctional aziridin. The reverse side layer can be printed with thermal printers with only slight absorption of dirt and discoloration from developer baths, and has good adhesion of adhesive tape, good printability with conventional printers, good resistance to abrasion and baths, and a good antistatic properties.
