Abstract
Official abstract text for this publication.
A gas-barrier laminate film ( 5 ) which includes a film base material ( 1 ), a layer ( 2 ) that contains an inorganic compound (A) and is formed on one surface of the film base material, and two layers formed on the layer that contains the inorganic compound (A) so as to be adjacent to each other, wherein the two layers are made up of a layer ( 3 ) that contains a carboxylic acid polymer (B) and a layer ( 4 ) that contains at least one selected from a group consisting of a silicon compound (C) represented by the following general formula (I) and a hydrolysate thereof, and a vinyl alcohol polymer (D): Si(OR 1 ) 4 (I) (where R 1 represents an alkyl group with 1-4 carbon atoms, and the four R 1 s may be identical or different).
First claim
Opening claim text (preview).
What is claimed is: 1 . A gas-barrier laminate film comprising: a film base material; a first layer that contains an inorganic compound (A) that is formed on one surface of the film base material, two layers formed on the first layer that contain the inorganic compound (A) so as to be adjacent to each other, wherein the two layers are made up of a layer that contains a carboxylic acid polymer (B) and a layer that contains at least one selected from a group consisting of a silicon compound (C) represented by the following general formula (1) and a hydrolysate thereof, and a vinyl alcohol polymer (D): Si(OR 1 ) 4 (1) (where R 1 represents an alkyl group with 1-4 carbon atoms, and the four R 1 s may be identical or different). 2 . The gas-barrier laminate film according to claim 1 , wherein the first layer that contains the inorganic compound (A) is formed by a vapor deposition method. 3 . The gas-barrier laminate film according to claim 1 , wherein the first layer contains at least one inorganic compound (A) selected from a group consisting of aluminum, aluminum oxide, tin oxide, magnesium oxide, and silicon oxide.
