    • This invention relates to hydroxyalkylated chitosan solution characterized in that a hydroxyalkylated chitosan and an organic acid or its derivative are contained in an aprotic polar solvent. This invention also relates to a coating process of a substrate, which is characterized by a step of causing the hydroxyalkylated chitosan solution to adhere onto a surface of the substrate, and another step of heating the substrate, which has been obtained in the first-mentioned step, at 100° C. or higher for 1 second or longer. This invention can provide a one-pack solution of a chitosan derivative, which is free from crosslinking and stable at room temperature, can form a chitosan coating excellent in waterproofness after heated and dried, and is suited for the coating of a hydrophobic or lipophilic surface. This invention also provides a coating process of a substrate, which makes use of the one-pack solution.
    • 本发明涉及羟烷基化壳聚糖溶液,其特征在于在非质子极性溶剂中含有羟烷基化的壳聚糖和有机酸或其衍生物。 本发明还涉及一种基材的涂布方法,其特征在于使羟烷基化的壳聚糖溶液粘附在基材的表面上,另一步是加热基材,该步骤已经在前述的 步骤,在100℃以上1秒以上。 本发明可提供壳聚糖衍生物的单组分溶液,其在室温下无交联和稳定,可形成加热干燥后防水性优异的壳聚糖涂层,适用于疏水或亲油表面的涂布 。 本发明还提供了使用单组分溶液的基材的涂布方法。
