Thermosetting powder coating compositions and processes for making the thermosetting powder coating compositions and processes for coating an article with the thermosetting powder coating compositions are disclosed. Cured thermosetting powder coating compositions are obtained by curing of the thermosetting powder coating compositions of the invention. Articles are provided having coated thereon the thermosetting powder coating compositions as well as to articles having coated and cured thereon the thermosetting powder coating compositions. The thermosetting powder coating compositions exhibit a substantially lower T.sub.chalk-free, that is a ΔT.sub.chalk-free which is in the range of from and including 5 up to and not including 10° C., wherein ΔT.sub.chalk-free=T.sub.chalk-free.sup.REF−T.sub.chalk-free.sup.A where T.sub.chalk-free.sup.A is the T.sub.chalk-free of a thermosetting powder coating composition according to the invention (TPCC-A) and T.sub.chalk-free.sup.REF is the T.sub.chalk-free of a thermosetting powder coating composition not according to the invention (TPCC-REF) that is comparable to TPCC-A.

A nail sticker, a composition for the nail sticker and a method for preparing the composition are disclosed. Raw materials of the composition include a sizing material, which is made of the following raw materials in parts by weight: 45-85 parts of a UV thermosetting resin, 2-9 parts of a photoinitiator, 1.5-2 parts of a curing agent, 0.1-1 part of a thermal promoter, and 0.1-1 part of a leveling agent. The synchronization of the release of essential oil molecules with light/thermal curing promotes the essential oil molecules to be diffused to the interior of the sizing material more uniformly in a wider range, and during the curing and film forming of the nail sticker, an aroma spreads as tantalizing as that of baked food.

Provided is a prepreg containing a urethane (meth)acrylate (A), an ethylenically unsaturated monomer (B), a polymerization initiator (C), and reinforcement fibers (D), characterized in that the urethane (meth)acrylate (A) is a reaction product of a polyisocyanate (a1) and a polyol (a2) having an ethylenically unsaturated group and an aromatic skeleton, and/or a reaction product of a polyisocyanate (a1), a polyol (a3) not having an ethylenically unsaturated group but having an aromatic skeleton, and a hydroxyalkyl (meth)acrylate (a4), and that the ethylenically unsaturated monomer (B) has a molecular weight of 320 or more and a weight reduction rate (%) of less than 2 when heated under atmospheric pressure at 150° C. for 3 minutes. The prepreg has excellent moldability and enables to produce a molded article having excellent physical properties such as flexural strength and interlaminar shear strength, and therefore the prepreg can be suitably used in automobile components and the like.
