Title:
RESIN COMPOSITION FOR COATING AND METHOD FOR PRODUCING COATING FILM
Document Type and Number:
WIPO Patent Application WO/2021/200853
Kind Code:
A1
Abstract:
The present invention provides a resin composition for coating, said resin composition being able to be visualized immediately after the application, while being capable of suppressing functional deterioration of a coating film after the application due to the elimination of fluorescence function with time. A resin composition for coating, which contains a resin, a fluorescent agent and a solvent, and wherein: with respect to the fluorescent agent, the weight loss rate is from 3.0% to 11% as measured at 80°C for one hour by TG-DTA, the common logarithm of the molar extinction coefficient with respect to light having a wavelength of from 350 nm to 400 nm is 3 or more, and the fluorescence wavelength is from 400 nm to 800 nm; the solvent has a boiling point of from 35°C to 150°C; the Gardner color scale in accordance with JIS K 0071-2 is 9 or less; and the film formation temperature is 80°C or less.
