The instant invention pertains to a curable composition comprising(a) substance that generates free radicals under the action of ultraviolet radiation and(b) polymer molecule bearing functionality capable of polymerization under the action of said free radicals wherein (a) is a benzoin ether and makes up from 0.001 to 10 wt % of the total composition and (b) has the following formulain which R, R', and R'' are each H or C1 to C10 hydrocarbyl possibly containing a heteroatom and at least 10 % is, for example, a vinyl group, and a+b+c+d=1. The composition of the instant invention is a storage-stable UV-curable composition that does not suffer from cure inhibition by air or oxygen, that is very efficiently cured by low doses of UV radiation, and provides a highly heat-resistant cured pattern by heating after pattern formation.

The invention discloses a special anticorrosive powder coating for a high-decorativeness pure polyester aluminum section and a preparation method of the powder coating. The powder coating comprises the following raw materials: carboxyl-terminated polyester resin, triglycidyl isocyanurate, titanium dioxide, ultrafine barium sulfate, a charging additive, a dry flow additive, benzoin, a leveling agent and a brightening agent. The preparation method mainly comprises the following steps: firstly, uniformly premixing the raw materials; secondly, performing melt extrusion; finally, performing crushing and ultrafine grinding. The powder coating prepared by the method is strong in adaptability to different thickness of coatings, and has relatively good leveling effects on thick coating (not less than 120 microns) and thin coating (not more than 60 microns); especially, the phenomena of melt falling and non-uniform thickness of powder applied to a workpiece due to influence of gravity on the powder product sprayed by vertical spraying equipment at the construction site in baking and curing processes are greatly reduced, and a paint film is excellent in appearance and free of particle phenomenon during thin coating.
