The present invention relates to an agent in particular for the surface epilamization of an article comprising one or more molecules having the general formula (1)
A-F(1)
wherein: A is an anchor group comprising a moiety selected from the group consisting of silane groups, hydroxyl groups, catechol groups, phosphate groups, phosphonate groups, carboxylic acid groups, amine groups, thiol groups and any combination of two or more of the aforementioned groups and F is a functionalizing group, wherein the functionalizing group com-prises a branched polymer having a backbone and at least two side groups, wherein at least one of the side groups is a C1-20 hydrocarbon group or a perhalogenated C1-20 hydrocarbon group. The invention pertains to the technical field of epilame for timepiece mechanical parts.

A lubricant for magnetic media is synthesized using click chemistry. In one aspect the lubricant is according to general formula (I):

##STR00001##

where Rc is a fluorinated or non-fluorinated divalent linking segment; where each Re.sup.1 and Re.sup.2 is a click linker moiety that can be triazole or sulfone; n is from 2 to 50; where each Rb.sup.1 and Rb.sup.2 is an optionally non-fluorinated divalent linking segment optionally comprising at least one least one first anchoring functional group engageable with a protective overcoat of a magnetic recording medium; and where each of Rv.sup.1 and Rv.sup.2, when present, independently comprises a moiety having at least one second anchoring functional group engageable with the protective overcoat of the magnetic recording medium. The click linker moiety may also functional as an anchoring functional group.
