Abstract
1293661 Graft polymers INTERNATIONAL POLAROID CORP 12 Jan 1970 [13 Jan 1969] 1456/70 Addition to 1230181 Heading C3G [Also in Division G2] A receiving sheet for the photographic silver salt diffusion transfer process (see Divisions G2-G3) contains a graft copolymer of one of the formulµ (in which Z is an organic polymeric backbone unit having repeating units capable of being oxidized by transition metal ions having an oxidation potential of at least one volt when it is reduced to the next lower stable state; each X is optionally substituted carboxamido, carbamyl, sulphonamido or sulphamyl; each R is H or 1-5 C alkyl; K is a monomer unit; M is at least one; P is greater than 1; Q and J are at least 2 and denote a plurality of the respective side chains; N is equal to or greater than zero; N is not zero and K is not identical with -CH 2 -CXR- when X is carboxamido or carbamyl and Z is polyvinyl alcohol). Specified graft copolymers are DAA/AA, DAA/acrylonitrile, AA/ispAA, DAA/Vac, Vac/ispAA, ispAA/methyl methacrylate p-styrene sulphonamide, N-isopropyl ethylene sulphonamide and ispAA/N-vinylpyrrolidone grafts on polyvinylalcohol, DAA/AA graft on partially hydrolysed polyVac, ispAA graft on gelatine, DAA grafts on polyvinyl partial methoxy acetal and partial dimethylaminobenzal and DAA and DAA/ ethylacrylate grafts on methyl hydroxypropyl cellulose (in which AA is acrylamide, DAA is diacetone acrylamide, Vac is vinylacetate and isp AA is isopropylacrylamide). The different monomers may be grafted sequentially or simultaneously preferably using a transition metal ion (e.g. V<SP>5+</SP>, Ce<SP>4+</SP> or Cr<SP>6+</SP> as catalyst).
