The present invention relates to novel derivatives of (poly)alkoxylated (per)fluoropolyethers, also referred to as PFPE-PAGs, comprising unsaturated end groups bearing acrylate, allylic or vinylic moieties.

The present invention relates to the use of (per)fluoropolyether polymer derivatives comprising acrylate moieties as additive in solvent-based formulations for coating substrates, notably glass, metal and plastic. In addition, the present invention further relates to certain novel (per)fluoropolyether polymer derivatives comprising acrylate moieties.

A fluorinated compound represented by D.sup.1-R.sup.f1OCH.sub.2(C.sub.mF.sub.2mO).sub.n-A (wherein D.sup.1 is CF.sub.3 or CF.sub.3O, R.sup.f1 is a C.sub.1-20 fluoroalkylene group containing at least one hydrogen atom, a C.sub.2-20 fluoroalkylene group containing at least one hydrogen atom and having an etheric oxygen atom between carbon-carbon atoms, etc., m is an integer of from 1 to 6, n is an integer of from 1 to 200, and A is a monovalent organic group having at least one (meth)acryloyl group), which is capable of imparting excellent antifouling properties (oily ink repellency, fingerprint stain removability) and lubricity to e.g. a hard coat layer; a hard coat layer-forming composition which contains such a fluorinated compound; and an article having a hard coat layer formed from such a composition.

A novel polymer comprising a water soluble polymer backbone, at least one functional group attached to the polymer backbone and having an affinity for titanium dioxide, and at least one hydrophobic functional group attached to the polymer backbone and having an affinity for latex is provided. A titanium dioxide pigment composition including the novel polymer is also provided. Also provided is a method of manufacturing a titanium dioxide pigment composition that includes the novel polymer.
