Composition having improved adherence with an addition-curable material and composite article incorporating the composition

A composition having improved adherence with an addition-curable material, said composition comprising:

• a resin component that is organic and polymeric and free of ethylenically unsaturated and silicon hydride functional groups;
• and
• an additive incorporated into said resin component and comprising an unsaturated carboxylic acid or carboxylic acid salt, wherein said additive comprises a hydrosilylation reactive group for reaction with the addition-curable material,
• wherein said hydrosilylation reactive group of said additive comprises a silicon hydride functional group for reaction with the addition-curable material.
