The present invention provides a resin composition comprising: (A) 100 parts by weight of epoxy resin; (B) from 10 to 80 parts by weight of benzoxazine resin; (C) from 10 to 50 parts by weight of dicyclopentadiene phenol resin; and (D) from 0.5 to 5 parts by weight of amine hardener; wherein the resin composition is free of diallyl bisphenol A (DABPA).

Shielding coatings are applied to polymer substrates for selective metallization of the substrates. The shielding coatings include a primer component and a hydrophobic top coat. The primer is first applied to the polymer substrate followed by application of the top coat component. The shielding coating is then selectively etched to form an outline of a desired current pattern. A catalyst is applied to the patterned polymer substrate followed by electroless metal plating in the etched portions. The portions of the polymer substrate which contain the shielding coating inhibit electroless metal plating. The primers contain polyamines and the top coat contains hydrophobic alky organic compounds.

Disclosed herein are aspects and embodiments of hydrophilic polymeric blend and polymeric membranes which may be formed from the hydrophilic polymeric blend. In one example, the polymeric blend includes a hydrophobic membrane forming polymer and a polyoxazoline as a blend compatible hydrophilizing additive.
