First claim
Opening claim text (preview).
The invention claimed is: 1. An oxygen-absorbing resin composition containing an ethylene terephthalate polyester resin and an organic oxygen absorber and, further, containing cobalt in an amount of 5 to 50 ppm and titanium in an amount of 1 to 15 ppm calculated as elements, wherein the organic oxygen absorber is a bisimide compound derived from an acid anhydride and a diamine. 2. The oxygen-absorbing resin composition according to claim 1 , wherein said cobalt is contained at a concentration of 10 to 30 ppm. 3. The oxygen-absorbing resin composition according to claim 1 , wherein said organic oxygen absorber is contained in an amount of 0.5 to 2.0% by mass. 4. The oxygen-absorbing resin composition according to claim 1 , wherein said acid anhydride is represented by the following formula (1): wherein the ring X is an aliphatic ring having an unsaturated bond, and Y is an alkyl group. 5. The oxygen-absorbing resin composition according to claim 1 , wherein said organic oxygen absorber has a molecular weight of not more than 1000. 6. The oxygen-absorbing resin composition according to claim 4 , wherein said organic oxygen absorber is an aliphatic bisimide compound derived from said acid anhydride and an aliphatic diamine. 7. A formed body of a single-layer or a multilayer structure having a layer formed by using the oxygen-absorbing resin composition described in claim 1 . 8. The formed body according to claim 7 , wherein the formed body is a container. 9. The formed body according to claim 7 , wherein the formed body is a preform for forming a container.
