    摘要： A surface-treating agent comprising a perfluoro(poly)ether group-containing compound represented by the formula (A): Rf-(PFPE-Z 1 -Y-Z 2 ) n -R. In the formula; Rf represents an alkyl group having 1 to 16 carbon atoms and optionally substituted by one or more fluorine atoms; PFPE at each occurrence is independently a group represented by formula: - (OC 6 F 12 ) a -(OC 5 F 10 ) b -(OC 4 F 8 ) c -(OC 3 F 6 ) d -(OC 2 F 4 ) e -(OCF 2 ) f -; Z 1 and Z2 at each occurrence are independently a single bond or a divalent organic group; Y at each occurrence independently represents a group comprising at least one -O-; provided that at least one structure formed of two or more continuous oxygen atoms is present in formula (A); n is an integer of 1 to 400; R is a hydrogen atom, a fluorine atom, -CF 2 -Cl, -COF, -COOH, -PFPE-Rf' or Rf'; and Rf' has the same definition as that of Rf.

    摘要： The present invention provides a perfluoro(poly)ether group containing silane compound which is able to form a layer having water-repellency, oil-repellency and antifouling property as well as high friction durability, and represented by the formula (1a) or the formula (1b):

            A - Rf - X - SiQ k Y 3-k ▪▪▪     (1a)

            Y 3 - k Q k Si-X-Rf-X- SiQ k Y 3-k ▪▪▪     (1b)

    wherein A represents a C 1-16 alkyl which may be substituted by one or more fluorine atoms;
    Rf represents -(OC 9 F 8 ) a -(OC 3 F 6 ) b -(OC 2 F 4 ) c -(OCF 2 ) d -wherein a, b, c and d are each independently an integer of 0 or more and 200 or less, the sum of a, b, c and d is 1 or more and the occurrence order of the respective repeating units in parentheses with the subscript a, b, c or d is not limited in the formula;
    X represents a divalent organic group;
    Y represents, each independently at each occurrence, a hydroxyl group, a hydrolyzable group, or a hydrocarbon group;
    Q represents, each independently at each occurrence,-Z-SiR 1 n R 2 3 - n ;
    Z represents, each independently at each occurrence, a divalent organic group: with the proviso that Z is not a group which forms a siloxane bond together with a Si atom present in the end of a molecular backbone of the formula (1a) or the formula (1b),
    R 1 represents, each independently at each occurrence, a hydroxyl group or a hydrolyzable group;
    R 2 represents, each independently at each occurrence, a C 1-22 alkyl group or Q';
    Q' has the same definition as that of Q;
    n is, each independently in each Q and Q', an integer selected from 0-3, and the total sum of n one or more;
    in Q, the number of Si atoms which are straightly linked via the Z group is up to five;
    k is an integer each independently selected from 1-3.
