COATING SOLUTION FOR FORMATION OF LOW REFRACTIVE INDEX COATING FILM, METHOD FOR PRODUCTION OF THE SAME, AND ANTI-REFLECTION MATERIAL

摘要

Disclosed is a coating solution for forming a coating film, which can be cured at a low temperature even on a substrate having a high water contact angle, and can form a coating film having high light transmissivity, high hardness, excellent scratch resistance and a low refractive index. Also disclosed is a method for producing the coating solution. Further disclosed is an anti-reflection material utilizing the coating film. Specifically disclosed is a coating solution for forming a low refractive index coating film, which comprises: a polysiloxane (A) which has a silicon atom having a fluorinated organic group bound thereto; a linear alkylamine compound (B) having 20 or less carbon atoms; and an amine compound (C) which has 20 or less carbon atoms in total and has a cyclic group having 10 or less carbon atoms in its structure.
