Document Type and Number:

Japanese Patent JP5589386

Kind Code:

B2

Abstract:

Disclosed is a hydrophilic coating film having antifog properties due to high hydrophilicity in addition to hardness, water resistance and alkali resistance. Specifically disclosed is a hydrophilic coating agent characterized by containing a colloidal silica sol (A), an acrylic polymer (B) having an active hydrogen and a weight average molecular weight of 5,000-200,000, a reactive silane coupling agent (C), and a curing agent (D) for the acrylic polymer (B). This hydrophilic coating agent is also characterized in that the mass ratio between the component (A) and the component (B), namely (A)/(B) is within the range of from 5/95 to 95/5, and the mass ratio between the total of the component (A) and the component (B) and the component (C), namely (A + B)/(C) is within the range of from 30/70 to 95/5.
