The invention concerns methods and compositions for modifying a surface of a material by anchoring a surface modifying additive to a polymer matrix using an anchor molecule, wherein the surface modifying additive and the anchor molecule are both added to a melt phase of the polymer matrix.

Provided is a coating agent which can be stably immobilized on metal surface, and which can give blood compatibility. Provided is a copolymer which is usable as the above-mentioned coating agent that comprises PEG segment and a segment which has a phosphoric acid residue (PO(OH).sub.2) and a cyclic nitroxideradical randomly as a side chain or a pendant group.

The present invention relates to a pre-treatment liquid providing improved spreading property when printing an ink-jet image, as well as an ink-jet printing method comprising applying the pre-treatment liquid of the invention on a recording medium prior to printing an ink-jet image and a method of pre-treating a recording medium, comprising pre-treating a recording medium with the pre-treatment liquid of the invention. With the present pre-treatment liquid a combination an improved spreading of the ink on the pre-treated recording medium can be achieved.

The present disclosure provides a primer composition. In an embodiment, the primer composition includes a functionalized polyolefin, a functionalized styrenic block copolymer containing greater than or equal to 20 wt % polymerized styrene, a solvent composition and an isocyanate component.
