<p><P>PROBLEM TO BE SOLVED: To obtain a gas barrier coating agent composition of one-pack type, which gives a gas barrier laminated film of a practical use having an excellent gas barrier property, causing no deterioration of gas barrier property under high temperature and high humidity, and not causing whitening of a coated film, wherein content in the film can be easily seen, a metal detector can be used and the environmental load is very little. <P>SOLUTION: The gas barrier coating agent composition comprises an alkali metal salt silicate (A), an organic polymer (B) containing a hydroxy group, a silane coupling agent (C) containing a hydrophilic group (including a potential hydrophilic group which gains hydrophilicity by reacting in the system), one or more kinds of metal compounds (D) selected from alkoxides and chelate compounds of Al, Ti, Zr, Sn and/or at least one kind of alkoxy silane (E) expressed by the formula: R<SP>1</SP>nSi(OR<SP>2</SP>)<SB>4-n</SB>(wherein R<SP>1</SP>and R<SP>2</SP>are each independently a 1-4C alkyl group, (n) is an integer of 0 or 1)(with the proviso that C,D and E may contain independently their hydrolized products). <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
