    摘要: 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.
