Document Type and Number:

WIPO Patent Application WO/2023/167206

Kind Code:

A1

Abstract:

An anti-fogging agent that contains silica particles and a solvent, wherein, when the contact angle is measured using a contact angle meter under the following condition A, the regression coefficient Δθ50-100 of the regression line obtained from the contact angle measured from 50 seconds to 100 seconds elapsed and the elapsed time is smaller than 0.　Condition A: In an environment at 25°C and 65% RH, 0.5 μL of the anti-fogging agent is dropped onto a PTFE substrate and the contact angle is measured every 5 seconds, by referring the time at which the anti-fogging agent comes into contact with the PTFE substrate as 0 seconds.
