[Problem] The purpose of the present invention is to obtain a multifunctional (meth)acrylate with good yield by an ester exchange reaction of a polyhydric alcohol such as pentaerythritol or dipentaerythritol with a monofunctional (meth)acrylate.
[Solution] A multifunctional (meth)acrylate manufacturing method characterized in that when manufacturing a multifunctional (meth)acrylate by an ester exchange reaction of a polyhydric alcohol with a monofunctional (meth)acrylate, catalyst (A) and catalyst (B) are used together. Catalyst (A): One or more kinds of compounds selected from a group consisting of cyclic tertiary amines with an azabicyclo structure or salts or complexes thereof, amidines or salts or complexes thereof, and compounds with a pyridine ring or salts or complexes thereof. Catalyst (B): One or more kinds of compounds selected from a group consisting of zinc-containing compounds.

Organic solvent soluble, acryloyloxy and methacryloyloxy group-containing, condensation polymers are crosslinkable and useful for providing chemical, solvent, and abrasion resistant articles. The condensation polymers are polyesters or polyurethanes having an acryloyloxy or methacryloyloxyalkanediol component that is uncontaminated by hydroxyl group-containing compounds having one, three, or more hydroxyl groups or compounds in which the acryloyloxy or methacryloyloxy group is attached to a secondary carbon atom.

A radiation curable liquid includes at least one free radical polymerizable monomer or oligomer, at least one diffusion hindered acetalysation catalyst, and at least one diffusion hindered hydroxyl containing compound. The radiation curable liquid applied to a substrate prevents migration of very low viscous monomers, such as vinyl ether acrylate monomers, into the substrate.
