Curable resin composition comprised from curable resin containing a polymerizable unsaturated group and an aprotic onium-containing group of the following general formula (I). [Wherein R ₁ means a hydrogen atom or a hydrocarbon group of 1 to 8 carbon atoms which may be optionally substituted by a hydroxyl group, an alkoxy group or an ester group or a halogen atom; (Wherein Z means a nitrogen atom or a phosphorus atom; Y means a sulfur atom; R ₂ , R ₃ and R ₄ are the same or different and each represents an organic group of 1 to 14 carbon atoms, R ₂ and R ₃ or R ₂ , R ₃ and R ₄ together may form a heterocycl group with adjacent nitrogen, phosphorus or sulfur atoms.] The composition of claim 1, wherein the resin has a peak molecular weight of about 250 to 100,000 as measured by gel permeation chromatography. The composition of claim 1 wherein said resin has at least one polymerizable unsaturated group per molecule. The composition of claim 1 wherein the polymerizable unsaturated group content per kg solid resin of the resin is from about 0.1 to 10 moles and the onium-containing group content is from about 0.01 to 5 moles. The polymerizable unsaturated group is at least acryloyl group, methacryloyl group, itaconoyl group, maleoyl group, fumaroyl group, crotonoyl group, acrylamido group, methacrylamido group, cinnamoyl group, vinyl Composition selected from the group consisting of a group and an allyl group. The composition of claim 1 wherein the resin is acrylic, polyester, urethane, alkyd, epoxy or phenolic. Curable resin composition comprised from (a) polymeric unsaturated group containing resin, and (b) curable resin containing the aprotic onium-containing group of following General formula (I). [Wherein R ₁ means a hydrogen atom or a hydrocarbon group of 1 to 8 carbon atoms which may be optionally substituted by a hydroxyl group, an alkoxy group or an ester group or a halogen atom; Wherein Z is a nitrogen atom or a phosphorus atom; Y is a sulfur atom; R ₂ , R ₃ and R ₄ are the same or different and each represents an organic group of 1 to 14 carbon atoms, R ₂ and R ₃ or R ₂ , R ₃ and R ₄ together may form a heterocycl group with adjacent nitrogen, phosphorus or sulfur atoms.] 8. The composition of claim 7, wherein the resin (a) is a resin containing a hydroxyl group. 8. The composition of claim 7, wherein the peak molecular weight of resin (a) is about 250 to 100,000 by gel permeation chromatography measurements. 8. The composition of claim 7, wherein said resin has at least one polymerizable unsaturated group per molecule. 8. The composition of claim 7, wherein the polymerizable unsaturated group content of resin (a) is from about 0.1 to 10 moles per kg of solid resin. 8. The polymerizable unsaturated group is at least an acryloyl group, methacryloyl group, itaconoyl group, maleoyl group, fumatoyl group, crotonoyl group, acrylamido group, methacryl amido group, cinnamoyl group. Composition selected from the group consisting of vinyl and allyl groups. 8. The resin of claim 7, wherein the resin (a) is acrylic, polyester, urethane, alkyd. Compositions that are epoxy or phenolic. 8. The composition of claim 7, wherein the resin (b) has a peak molecular weight of about 150 to 100,000 by gel permeation chromatography measurements. 8. The composition of claim 7, wherein the onium-containing content of resin (b) is about 0.01 to 5 moles per kg solid resin. 18. The composition of claim 17, wherein the resin (b) is acrylic, polyester urethane, alkyd, epoxy or phenolic. ※ Note: The disclosure is based on the initial application.
