Abstract

Provided are: a (hydrolyzable) organosiloxane compound which is represented by general formula (1) and contains a lipophilic group capable of forming a cured film having excellent lipophilicity and wear resistance; and a surface treatment agent containing the compound.

(In the formula, A is any one among —CH 3 , —C(═O)OR 1 , —C(═O)NR 1 2 , —C(═O)SR 1 , and —P(═O)(OR 1 ) 2 ; R 1 is a hydrogen atom, a C1-30 alkyl group, a C6-30 aryl group, or a C7-30 aralkyl group; Y is independently a divalent organic group; W is independently a C1-4 alkyl group, a phenyl group, a hydroxyl group, or a hydrolyzable group; R is independently a C1-4 alkyl group or a phenyl group; X is independently a hydroxyl group or a hydrolyzable group; n is an integer of 1-3; and q is an integer of 1-3.)

First claim

The invention claimed is:

1. An organosiloxane compound having the general formula (1):

wherein A is —C(═O)OR 1 , —C(═O)NR 1 2 , —C(═O)SR 1 , or —P(═O)(OR 1 ) 2 , R 1 is hydrogen, a C 1 -C 30 alkyl group, C 6 -C 30 aryl group, or C 7 -C 30 aralkyl group, Y is independently a divalent organic group, W is independently a C 1 -C 4 alkyl group, phenyl group, hydroxyl group or hydrolyzable group, R is independently a C 1 -C 4 alkyl group or phenyl group, X is independently a hydroxyl group or hydrolyzable group, n is an integer of 1 to 3, and q is an integer of 1 to 3.

2. The organosiloxane compound of claim 1 , having the general formula (2):

wherein R 2 is a C 1 -C 20 alkyl group, C 6 -C 20 aryl group or C 7 -C 20 aralkyl group, Q is a single bond or a divalent group selected from among silalkylene, silarylene, and straight, branched or cyclic divalent organopolysiloxane residues of 2 to 10 silicon atoms, m is each independently an integer of 1 to 20, and X is independently a hydroxyl group or hydrolyzable group.

3. The organosiloxane compound of claim 1 wherein in formula (1), X is each independently selected from the group consisting of hydroxyl, C 1 -C 10 alkoxy, C 2 -C 10 alkoxy-substituted alkoxy, C 1 -C 10 acyloxy, C 2 -C 10 alkenyloxy, halogen, oxime, isocyanate, and cyanate.

4. A surface treating agent comprising the organosiloxane compound of claim 1 .

5. The organosiloxane compound of claim 2 wherein in formula (2), X is each independently selected from the group consisting of hydroxyl, C 1 -C 10 alkoxy, C 2 -C 10 alkoxy-substituted alkoxy, C 1 -C 10 acyloxy, C 2 -C 10 alkenyloxy, halogen, oxime, isocyanate, and cyanate.
