First claim

Opening claim text (preview).

What is claimed is: 1. A composition, comprising: 49% to 86% by mass relative to the total amount of the composition of an acrylamide compound; urethane (meth)acrylate; and a polymerization initiator, wherein the composition has a Simulation Index (SI) value of 3 or less in a skin sensitization test, wherein the polymerization initiator is at least one selected from the group consisting of polyethylene glycol 200-di(β-4(4-(2-dimethylamino-2-benzyl)butanonylphenyl)piperazine), 1,3-di({α-[1-chloro-9-oxo-9H-thioxanthen-4-yl)oxy]acetyl poly[oxy(1-methylethylene)]}oxy)-2,2-bis({α-[1-chloro-9-oxo-9H-thioxanthen-4-yl)oxy]acetyl poly[oxy(1-methylethylene)]}oxymethyl)propane, a mixture of 1,3-di({α-4-(dimethylamino)benzoyl poly[oxy(1-methylethylene)]}oxy)-2,2-bis({α-4-(dimethylamino)benzoyl poly[oxy(1-methylethylene)]}oxymethyl)propane with {α-4-(dimethylamino)benzoyl poly(oxyethylene)-poly[oxy(1-methylethylene)]-poly(oxyethylene)}4-(dimethylamino) benzoate, polybutylene glycol bis(9-oxo-9H-thioxanthinyloxy) acetate, and oligomers of 2-hydroxy-1-(4-isopropenylphenyl)-2-methylpropane-1-one, wherein the acrylamide compound is selected from acrylamides A1-1 to A1-5 2. The composition according to claim 1 , wherein the acrylamide compound is A1-1. 3. The composition according to claim 1 , wherein a content of the urethane (meth)acrylate is 5% by mass to 40% by mass based on the total amount of the composition. 4. The composition according to claim 1 , wherein a content of the polymerization initiator is 1% by mass to 20% by mass based on the total amount of the composition. 5. The composition according to claim 1 , wherein the composition is an active-energy-ray-curable composition. 6. A stored container, comprising: the composition according to claim 1 ; and a container, wherein the composition is stored in the container. 7. A two-dimensional or three-dimensional image forming apparatus, comprising: a storing part which comprises a composition; an applying unit configured to apply the composition; and a curing unit configured to cure the composition, wherein the composition comprises a composition according to claim 1 . 8. A two-dimensional or three-dimensional image forming method, comprising: applying a composition; and curing the composition, wherein the composition comprises a composition according to claim 1 . 9. An artificial nail composition, comprising the composition according to claim 1 . 10. A nail decoration material, comprising the artificial nail composition according to claim 9 . 11. An artificial nail, comprising a cured product of the artificial nail composition according to claim 9 . 12. The composition according to claim 1 , wherein the polymerization initiator is at least one selected from the group consisting of polyethylene glycol 200-di(β-4(4-(2-dimethylamino-2-benzyl)butanonylphenyl)piperazine), 1,3-di({α-[1-chloro-9-oxo-9H-thioxanthen-4-yl)oxy]acetyl poly[oxy(1-methylethylene)]}oxy)-2,2-bis({α-[1-chloro-9-oxo-9H-thioxanthen-4-yl)oxy]acetyl poly[oxy(1-methylethylene)]}oxymethyl)propane, a mixture of 1,3-di({α-4-(dimethylamino)benzoyl poly[oxy(1-methylethylene)]}oxy)-2,2-bis({α-4-(dimethylamino)benzoyl poly[oxy(1-methylethylene)]}oxymethyl)propane with {α-4-(dimethylamino)benzoyl poly(oxyethylene)-poly[oxy(1-methylethylene)]-poly(oxyethylene)}4-(dimethylamino) benzoate, and polybutylene glycol bis(9-oxo-9H-thioxanthinyloxy) acetate. 13. The composition according to claim 1 , wherein the acrylamide compound is selected from acrylamides A1-2 to A1-5. 14. The composition according to claim 1 , wherein the composition comprises 10-40% of the urethane (meth)acrylate, and 5-10% of the initiator. 15. The composition according to claim 1 , which comprises 3-20% of the initiator, and 5-40% of the urethane (meth)acrylate. 16. The composition according to claim 1 , which consists essentially of the acrylamide, urethane (meth)acrylate, and initiator. 17. The composition according to claim 2 , wherein the composition comprises 10-40% of the urethane (meth)acrylate, and 5-10% of the initiator. 18. The composition according to claim 17 , which consists essentially of the acrylamide, urethane (meth)acrylate, and initiator. 19. An artificial nail comprising a cured product of the composition according to claim 18 .
