The present invention provides a water-soluble silicone macromer. The water-soluble silicone macromer has a general formula: E−(M.sub.1).sub.x−(M.sub.2).sub.y, wherein M.sub.1 is a repeating unit which is derived from a silicone containing monomer, M.sub.2 is a repeating unit which is derived from a first hydrophilic monomer, and E is an ethylenically unsaturated group. The amount of M.sub.1 is in a range of 30-60 wt % based on the total weight of the water-soluble silicone macromer, and the amount of M.sub.2 is in a range of 40-70 wt % based on the total weight of the water-soluble silicone macromer. A silicone hydrogel composition containing the water-soluble silicone macromer and a silicone hydrogel lens made of the silicone hydrogel composition are also provided herein.

The present disclosure is directed to actinic radiation curable polymeric mixtures, cured polymeric mixtures, tires and tire components made from the foregoing, and related processes.

Provided are a resin having a graft structure represented by Formula (1); a curable composition and a cured product of the resin; a color filter including the cured product; a solid-state imaging element or an image display device including the color filter; and a novel polymer compound. In Formula (1), P.sup.1 represents a polymer chain, X.sup.1 represents an alkylene group having a length of 3 or more atoms, L represents a single bond or a divalent linking group, and * represents a connection position with a structure including a main chain.
