摘要

PROBLEM TO BE SOLVED: To provide a glass plate with a smoothness improvement film, where the film can be formed or removed by a simple operation, and which has a novel coating film which can effectively improve smoothness.;SOLUTION: Provided is a glass plate with a smoothness improvement film, which has a smoothness improvement film 3 on an end face of a glass plate 2, the smoothness improvement film comprising a cationic surfactant containing an ammonium salt or pyridinium salt having a hydrophobic group having 8 or more carbon atoms, or a cationic polymer having an average molecular weight of 200 to 1 million. The smoothness improvement film 3 can improve smoothness significantly while having a single layer structure and being simple to handle, and can be removed easily by washing.;SELECTED DRAWING: Figure 1A;COPYRIGHT: (C)2016,JPO&INPIT
