<P>PROBLEM TO BE SOLVED: To provide a laminate, in which an aqueous dispersion liquid of minute cellulose exhibits superior coating suitability to a base material and the gas barrier properties of which are enhanced by restraining a layer comprising the minute cellulose from being deteriorated with time and to provide a method for manufacturing the laminate. <P>SOLUTION: The laminate comprising three layers is produced by layering the layer comprising the minute cellulose having a carboxyl group on the treated surface of the base material, whose surface is treated with plasma under atmospheric pressure at the least, and layering a heat-sealable thermoplastic resin layer on the layer comprising the minute cellulose. The method for manufacturing the laminate comprises the steps of: treating the base material with plasma under atmospheric pressure; forming the layer comprising the minute cellulose having the carboxyl group on the treated surface of the base material by a coating method; and layering the thermoplastic resin layer on the minute cellulose layer. <P>COPYRIGHT: (C)2012,JPO&INPIT |
