Title:
ガラス窓の視界を確保する方法
Document Type and Number:
Japanese Patent JP5018662
Kind Code:
B2
Abstract:
A glass window has a multiple glass structure in which a plurality of glass plates face each other, and a film is formed on the glass plate surface that is exposed to a cold environment when the glass window is closed. The film comprises a urethane resin prepared by a polymerization using at least a polyoxyalkylene-series polyol having an average molecular weight of 400-5000 and a hydrophobic polyol. There is used as the hydrophobic polyol an acrylic polyol having an average molecular weight of 500-5000 or a polyester polyol having an average molecular weight of 500-5000 and a hydroxy value of 10-200 mg KOH/g. Thereby, the film absorbs water that is in contact with the film when the glass window is open, and the film releases the water absorbed in the film when the opened door glass is closed, thereby having a condition that the film can absorb water.
