Abstract
A gas barrier laminated material comprising a substrate, and an inorganic compound thin-film layer and a protective layer which are laminated in this order, wherein the protective layer is a layer formed by coating on the inorganic compound thin-film layer a coating composition containing a metal alkoxide or a hydrolyzate thereof and an isocyanate compound having two or more isocyanate groups, followed by heat drying, or a layer formed by coating on the inorganic compound thin-film layer a water-based coating composition containing a water-soluble polymer and at least one of (a) a metal alkoxide or a hydrolyzate thereof and (b) a tin chloride, followed by heat drying.
Claims9
A gas barrier laminated material comprising a polymeric sheet or film, a layer of an inorganic compound having a thickness of from 50 to 3,000 angstroms on the polymeric sheet or film, and a protective layer having a thickness of from 0.01 to 100 .mu.m on the layer of the inorganic compound;
- wherein the protective layer is formed by coating the layer of the inorganic compound with a water-based coating coin position consisting essentially of a water-soluble polymer and from 10 to 1900 parts by weight per 100 parts by weight of the water-soluble polymer of at least one of (a) a metal alkoxide or a hydrolyzate thereof or (b) a tin chloride;
- and then heating and drying the water-based coating composition.
