Field: Basic materials chemistry (Chemistry)
Classification: CPC C  B | IPC B  C

Claim 6:
7. The oxygen-absorbing film according to claim 1 wherein the cured oxygen-absorbing adhesive resin composition comprises:
an oxygen-absorbing polyester-based resin (A) having a glass transition temperature of −20° C. to 10° C.; and;
wherein: a ratio A/B of the oxygen-absorbing polyester-based resin (A) to the saturated polyester resin (B) is 1.5 to 9,
the glass transition temperature of the saturated polyester resin (B) is lower than the glass transition temperature of the oxygen-absorbing polyester-based resin (A), and the oxygen-absorbing adhesive resin composition has a single-phase compatible system when the oxygen absorption starts, but has separated glass transition temperatures of two or more components due to reaction-induced phase separation following an oxygen absorption reaction.
