Title:
MIXED COMPOSITION
Document Type and Number:
WIPO Patent Application WO/2019/189790
Kind Code:
A1
Abstract:
The present invention addresses the problem of providing a mixed composition that is capable of realizing a film having excellent water repellency (in particular, droplet sliding properties), oil repellency, and sulfuric acid resistance.　The present invention pertains to a mixed composition of an organosilicon compound (A) in which at least one trialkylsilyl group–containing molecular chain and at least one hydrolyzable group are bonded to a silicon atom, a metal compound (B) represented by formula (b1), an acid (C) with a first dissociation pKa of 1 or higher, and water (D), wherein the amount of water (D) is more than 0 mass% to less than 2.20 mass%. In formula (b1), M represents Al, Fe, In, Ge, Hf, Si, Ti, Sn, Zr, or Ta, Rb10 represents a siloxane skeleton–containing group, a hydrocarbon chain–containing group, or a hydrogen atom, and r is 0 or 1. The plurality of Ab1 radicals each independently represent a hydrolyzable group, and m is an integer from 3 to 5 according to the metal atom M.　Formula (b1): M(Rb10)r(Ab1)m-r
