Fluoroacrylic compound, fluorine-containing actinic-ray-curable composition, and article

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 &#x2014;CH, &#x2014;C(&#x2550;O)OR, &#x2014;C(&#x2550;O)NR, &#x2014;C(&#x2550;O)SR, and &#x2014;P(&#x2550;O)(OR); Ris 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.)

Organosiloxane compound and surface treatment agent

According to the present invention, a surface treatment agent which contains a coating composition that contains (A) one or more compounds selected from among organosilane or siloxane compounds represented by formula (1) and partial (hydrolysis) condensation products of the compounds and (B) one or more compounds selected from among silane or siloxane compounds represented by formula (2) and partial (hydrolysis) condensation products of the compounds at a mass ratio of from 50:50 to 90:10 is able to form a cured coating film that has excellently low fingerprint visibility. (In formula (1), A represents &#x2014;C(&#x2550;O)OR, &#x2014;C(&#x2550;O)NR, &#x2014;C(&#x2550;O)SRor &#x2014;P(&#x2550;O)(OR); Rrepresents H, an alkyl group, an aryl group or an aralkyl group; Y represents a divalent organic group; R represents an alkyl group or a phenyl group; X represents a hydroxyl group or a hydrolyzable group; and n is 1-3.) (In formula (2), Rf represents a perfluoroalkylene group or a divalent perfluoropolyether group.)

Coating composition, surface treatment agent containing said composition, and article which is surface-treated with said surface treatment agent

By using this organosilane compound represented by formula (1), a surface treatment agent that contains said (hydrolyzable) organosilane compound and/or a partial (hydrolysis) condensate thereof can form a cured film which exhibits excellent lipophilic properties and has a refractive index similar to the refractive index of sebum. (A is any one of &#x2014;C(&#x2550;O)OR, &#x2014;C(&#x2550;O)NR, &#x2014;C(&#x2550;O)SRand &#x2014;P(&#x2550;O)(OR); Ris a hydrogen atom, an alkyl group, an aryl group or an aralkyl group; Y is a divalent organic group; R is an alkyl group or a phenyl group; X is a hydroxyl group or a hydrolyzable group; and n is 1-3.)
