Abstract

According to the present invention, a surface treatment agent which contains an organosilane compound represented by formula (1) and / or a partial (hydrolysis) condensation product thereof is able to form a cured coating film that has excellent lipophilic properties and a refractive index that is close to the refractive index of the sebum, while exhibiting excellent wear durability. (In formula (1), A represents one of -C(=O)OR1, -C(=O)NR1 2, -C(=O)SR1 and -P(=O)(OR1)2; R1 represents a hydrogen atom, an alkyl group having 1-30 carbon atoms, an aryl group having 6-30 carbon atoms or an aralkyl group having 7-30 carbon atoms; Y represents a divalent organic group; R represents an alkyl group having 1-4 carbon atoms or a phenyl group; R' represents an alkyl group having 1-20 carbon atoms, an aryl group having 6-20 carbon atoms or an aralkyl group having 7-20 carbon atoms; p represents 2 or 3; X represents a hydroxyl group or a hydrolyzable group; and n represents a number of 1-3.

Description

technical field [0001] The present invention relates to organosilane compounds and the like containing hydroxyl groups or hydrolyzable groups and lipophilic groups in their molecules. The surface treatment agent comprising the (hydrolyzable) organosilane compound containing the lipophilic group and / or its partial (hydrolyzed) condensate, and the surface treated with the surface treatment agent (that is, having the surface treatment agent on the surface cured coated) items, etc. Background technique [0002] In recent years, touch panelization of screens has been accelerated, including displays for mobile phones. However, the touch panel is in a state where the screen is exposed, and there are many opportunities for direct contact with fingers, cheeks, etc., and dirt such as sebum tends to adhere to it, which has become a problem. Therefore, in order to improve the appearance and visibility, the technology of making it difficult for fingerprints to adhere to the surface of ...
