PROBLEM TO BE SOLVED: To provide a barrier material which is a composite material that uses a polyhydroxyurethane resin having an excellent gas barrier property, mechanical strength, and transparency and decreased environmental load, especially that can realize a higher barrier property than when the hydroxyurethane resin is used alone.SOLUTION: Provided is a polyhydroxyurethane resin-silica hybrid composition comprising: a polyhydroxyurethane resin obtained by subjecting a compound having at least one five-membered cyclic carbonate group and a compound having at least one amino group to polyaddition reaction; and an alkoxysilane compound having at least one silanol group and/or a partial hydrolysis-condensation product of the same. Also provided is a method for producing a polyhydroxyurethane resin-silica hybrid solution. 【課題】ガスバリア性、機械強度および透明性に優れ、且つ、環境負荷を低減するポリヒドロキシウレタン樹脂を利用し、特に、単独のポリヒドロキシウレタン樹脂を用いた場合よりも高いガスバリア性を実現できる複合材料であるバリア性材料を提供すること。【解決手段】少なくとも１つの五員環環状カーボネート基を有する化合物と、少なくとも１つのアミノ基を有する化合物とを重付加反応させることより得られたポリヒドロキシウレタン樹脂と、少なくとも１つのシラノール基を有するアルコキシシラン化合物および／またはその部分加水分解縮合物とを含有してなるポリヒドロキシウレタン樹脂−シリカハイブリッド組成物、および、ポリヒドロキシウレタン樹脂−シリカハイブリッド溶液の製造方法。【選択図】なし
