The present invention is formed by coating a plastic substrate (A), an inorganic thin film (B) formed on at least one surface of the plastic substrate (A), and a coating agent containing a polyester resin on the surface of the inorganic thin film (B). In the gas barrier layered product formed of the polyester resin layer (C), the glass transition temperature of the polyester resin is 50 to 70 ° C, the molecular weight is 1500 to 15000, and the hydroxyl value is 10 to 60 mgKOH / g. Oxygen permeability of a laminated body is 5 cc / m < 2> / day / atm or less, and water vapor transmission rate is 5g / m < 2> / day or less, and it is related with the gas barrier laminated body. The gas barrier layered product of the present invention is excellent in printability (particularly, gray scale printability), and excellent in barrier properties even after printing, and has good adhesion between the plastic substrate (A) and the inorganic thin film when the retort treatment is performed. This is excellent.n n n Gas barrier property, laminate, printability, retort, adhesiveness |
