Disclosed is a method for producing resin particles, which can impart a desired function to the surface of resin particles efficiently and simply. Also disclosed are resin particles produced by the method. The method produces resin particles by melting and mixing an acidic-group-containing thermoplastic resin or elastomer with filler particles and a water-soluble material to give a resin composition containing resin fine particles formed by the thermoplastic resin and the filler particles and dispersed in a matrix including the water-soluble material; and removing the matrix component from the resin composition, to give the resin particles. The resulting resin particles each include a core particle including the acidic-group-containing thermoplastic resin or elastomer, and the filler particles immobilized on the outside of the core particle. The acidic group is preferably carboxyl group or carboxylic anhydride group.

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.

Disclosed are a carbonate group-modified epoxy resin in which carbonate groups are introduced into an epoxy resin having secondary hydroxyl groups at terminals or lactone-modified epoxy resin having primary hydroxyl groups at terminals by the ring-opening reaction of a cyclic alkylene carbonate, a process for the preparation thereof, and a thermosetting resin composition containing the carbonate group-modified epoxy resin.

Carbonate group-modified epoxy resin, a process for the preparation

A hydroxy-terminated linear carbonate is produced by reacting a cyclic alkylene carbonate such as neopentyl glycol carbonate with a substance having at least one alcoholic hydroxyl group in the presence of a catalyst. Mono- or polyhydric alphatic alcohols, polycaprolactone polyols, hydroxyl group-containing acrylic monomers and polymers, and polyester polyols are modified by the reaction with the cyclic alkylene carbonate to have an enhanced reactivity and resistance to hydrolysis.
