    摘要： Provided is a barrier film which is less likely to undergo deterioration of gas barrier properties even after the Gelbo Flex test. The barrier film according to the present invention includes a barrier coat layer, an inorganic oxide vapor deposition layer, and a substrate layer in this order, the barrier coat layer being a cured film of a barrier coat composition containing: a hydrolyzed product of an alkoxysilane represented by the following General Formula (I): Si(OR 1 ) 4 ... (I), wherein R 1 represents an organic functional group; a water-soluble polymer; and a hydrolyzed product of a silane coupling agent represented by the following General Formula (II): R 2 n Si(OR 3 ) 4-n ... (II), wherein R 2 and R 3 each independently represent an organic functional group, and n is 2 or 3.

    摘要： The present invention provides an outer package material for all-solid-state batteries, said outer package material being composed of a multilayer body that is sequentially provided, from the outer side, with at least a base material layer, a barrier layer, a bonding layer and a thermally fusible resin layer in this order, while being suppressed in delamination in a high temperature environment (specifically, separation of the barrier layer and the thermally fusible resin layer from each other in a high temperature environment). An outer package material for all-solid-state batteries, said outer package material being composed of a multilayer body that is sequentially provided, from the outer side, with at least a base material layer, a barrier layer, a bonding layer and a thermally fusible resin layer in this order, wherein the thermally fusible resin layer is formed of a polybutylene terephthalate film, and the boding layer is formed of a cured product of a resin composition that contains at least one of a polyester and a polycarbonate, and at least one of an alicyclic isocyanate compound and an aromatic isocyanate compound.
