ABSTRACT:
Disclosed are a novel (meth)acrylate having an alkenyl group, a novel epoxy(meth)acrylate, and processes for the preparation thereof. The (meth)acrylate having an alkenyl group of the present invention can be preferably used as resins for coatings, photo-curable resins, and adhesives by (co)polymerization thereof in the presence or absence of a variety of (meth)acrylic monomers, and the (meth)acrylate compound having an alkenyl group is useful as a silane coupling agent, a starting material for epoxy (meth)acrylates, a modifier for silicone resins, a modifier for unsaturated polyester resins, and a crosslinking agent for acrylic rubbers. The epoxy(meth)acrylate has a well-balanced excellent property between a pot life and reactivity in curing, and it does not contain chlorine, resulting in that a resin therefrom is excellent in an anti-corrosive property and an anti-yellowing property. Still further, the present invention relates to a (meth)acrylic resin having alkenyl groups as side chains, a (meth)acrylic resin having epoxy groups as side chains, and processes thereof. In addition, the present invention relates to a thermosetting resin composition, a coating composition and a powder coating composition which have anti-corrosive properties to substrates and anti-yellowing properties in coating layers.
