Title:
HYDROPHILIC GLIDING AGENT, SURFACE TREATMENT METHOD USING HYDROPHILIC GLIDING AGENT, AND BASE MATERIAL HAVING HYDROPHILIC GLIDING FILM FORMED THEREON
Document Type and Number:
WIPO Patent Application WO/2024/048468
Kind Code:
A1
Abstract:
A hydrophilic gliding agent (a) of the present invention contains an organosilicon compound (A) in which at least one hydrophilic chain-containing group and at least one hydrolysable group are bonded to at least one silicon atom, a metal alkoxide (B), and a silicone oil (C) having a hydrophilic chain-containing group having a molecular weight of 1000 or less. Alternatively, the hydrophilic gliding agent contains: an organosilicon compound (A2) in which three alkoxide groups, each having a hydrolysable group, are respectively bonded to silicon atoms at both ends; and the metal alkoxide (B). A process (2) of causing the hydrophilic gliding agent (a) to contact a base material surface makes it possible to achieve both high hydrophilic and gliding properties in comparison to the prior art and makes it possible to form a base material (c) having a hydrophilic gliding film having excellent hydrolytic stability. Furthermore, by subjecting the base material (c) to an alkali treatment or acid treatment (4), it is possible to further enhance the hydrophilic and/or gliding properties.
