    • PROBLEM TO BE SOLVED: To provide a hydrophilic coating material for glass for use in the window glass of a refrigeration showcase not becoming cloudy even under a low temperature atmosphere and to provide an outside mirror and a washing stand mirror excellent in anti-fogging properties, self-washing properties and abrasion resistance regardless of fine weather, rainy weather or day and night.
      SOLUTION: This hydrophilic resin coating material A is used so as to be applied to a glass base material 5 to form a silica-containing acrylic resin coating layer 4, which satisfies physical properties such that (1) the pencil hardness of the coating layer is 2H or above, (2) the coating layer has hydrophilicity wherein the contact angle of the coating layer with water is 10° or below and (3) the haze degree of the coating layer is 2% or below, on the surface of a cellulose triacetate film base material 3. Since the raindrop adhering to the silica-containing acrylic resin coating layer 4 spreads as a thin water film instantaneously, a visual field is not obstructed. Further, a mirror does not become cloudy by steam of exhalation or a hot spring.
