Title:
TRANSPARENT COATING FILM
Document Type and Number:
WIPO Patent Application WO/2016/068138
Kind Code:
A1
Abstract:
The purpose of the present invention is to achieve a good balance among water repellency/oil repellency, heat resistance and light resistance. A transparent coating film according to the present invention contains a polysiloxane skeleton and a trialkylsilyl group-containing molecular chain that is bonded to some silicon atoms among the silicon atoms constituting the polysiloxane skeleton, and is characterized in that: an alkyl group in the trialkylsilyl group-containing molecular chain may be substituted by a fluoroalkyl group; and if A0 is the initial contact angle of a liquid drop on the transparent coating film, BH is the contact angle after being left to stand at 200°C for 24 hours, and BL is the contact angle after being irradiated with light of a xenon lamp having an intensity of 250W for 100 hours, A0, BH and BL satisfy at least one of (BH - A0)/A0 × 100 (%) ≥ -27 (%) and (BL - A0)/A0 × 100 (%) ≥ -15 (%).
