Abstract: PURPOSE:To provide a base material or an article, excellent in water repellency and used for transportation, equipment. CONSTITUTION:A base material is obtained by forming two layers of a lower layer prepared by treating the surface with a hydrolyzable silane compound or its partial hydrolyzate and further treating the surface of the resultant lower layer with a fluorinecontaining hydrolyzable silane compound or its partial hydrolyzate or an article, composed of a base material having the aforementioned surface-treated layers as a constituent element, thus the base material useful for transportation equipment is provided. Glass requiring excellent see- through visibility is suitable as the base material. Window glass or mirrors are exemplified as the article for the transportation equipment. Since the aforementioned article has excellent water repellency and abrasion, chemical and weather resistances together, its effects are semipermanently sustained. Therefore, the above-mentioned article is excellent as an article for the transportation equipment under severe use environments.

In the formula, R1 to R5 are each a monovalent organic group (desirably, R1 to R5 is a group of the formula: -Q2-Rf, R2 to R4 are each a monovalent hydrocarbon group, or all of R1 to R5 are CH3 groups); Rf is a monovalent polyfluorohydrocarbon group optionally containing an etheric oxygen atom; Q2 is a divalent organic group; X1 to X3 are each a hydrolyzable group or NCO; and Q1 is a divalent organic group, desirably, dimethylene; and (m) is 0 or greater. The hydrolyzable silane compound of formula I is exemplified by a compound of formula II (wherein (x) and (y) are each 0-3, provided that x+y=3). This agent is incorporated with an organic solvent (e.g. butyl acetate) to obtain a surface treating agent composition for treating the surface of glass.
