    摘要： The invention relates to thermosetting powder coating compositions as disclosed herein, said compositions comprising one or more unsaturated resins comprising ethylenic unsaturations, one or more curing agents, and one or more thermal radical initiators, wherein at least one of the initiators is a peroxydicarbonate-X. The invention further relates to a process for making said thermosetting powder coating compositions and processes for coating an article with said thermosetting powder coating compositions. The invention further relates to cured thermosetting powder coating compositions obtained by curing of the thermosetting powder coating compositions of the invention. The invention further relates to an article having coated thereon said thermosetting powder coating composition as well as to an article having coated and cured thereon said thermosetting powder coating composition. The invention further relates to the use of said thermosetting powder coating compositions, to the use of an article having coated thereon said thermosetting powder coating compositions and to the use of an article having coated and cured thereon said thermosetting powder coating compositions. The invention further relates to various uses of either the thermosetting powder coating compositions of the invention, or the cured thermosetting powder coating compositions of the invention or of articles having coated thereon the thermosetting powder coating composition of the invention, or of articles having coated and cured thereon the thermosetting powder coating composition of the invention. The invention further relates to a method for enabling the fast heat-curing of a thermosetting powder coating composition at low temperature. The invention further relates to a method for enhancing the chemical resistance of a powder coating obtained by heat curing of the thermosetting powder coating composition of the invention at low temperature.

    摘要： An active energy ray-curable resin composition which is excellently adhesive to a base material, an undercoat agent which is for a metal thin film and includes the resin composition, and a formed material obtained using the undercoat agent for a metal thin film are provided. The active energy ray-curable resin composition includes, as essential components, an alkyd resin (A), an unsaturated bond-containing polymerizable compound (B), a phenolic compound (C) represented by the following structural formula (1)

    wherein R 1 is a hydrogen atom or a hydrocarbon group), and a photopolymerization initiator (D) having a structural moiety represented by the following structural formula (2)

    wherein R 3 ' s are any of an aliphatic hydrocarbon group, an aryl group, an aralkyl group, an alkoxy group, a hydroxyl group and an amino group, wherein two or more of the R 3 's may form a ring structure.

    摘要： The invention relates to a thermosetting powder coating composition C (PCC C) comprising a physical mixture of a thermosetting powder coating composition A (PCC A) with a separate, distinct thermosetting powder coating composition B (PCC B). The invention further relates to a process for making said thermosetting powder coating composition C and processes for coating an article with said thermosetting powder coating composition C. The invention further relates to a cured thermosetting powder coating composition C (c-PCC C). The invention further relates to an article having coated thereon said thermosetting powder coating composition C as well as to an article having coated and cured thereon said thermosetting powder coating composition C. The invention further relates to the use of PCC C for heat-curing at low temperatures. The invention relates also to a use of PCC C for making a cured PCC C, preferably said cured PCC C is a powder coating having one or multiple of properties such as excellent resistance to swelling, good smoothness, good chemical resistance, low gloss, low yellowness, in any combination. The invention further relates to the use of said thermosetting powder coating composition C, to the use of an article having coated thereon said thermosetting powder coating composition C and to the use of an article having coated and cured thereon said thermosetting powder coating composition C.
