First claim

What is claimed is:

1. An active energy ray curable composition, comprising:
an acrylamide compound A1 represented by the following Chemical formula 1 or the following Chemical formula 2;
a multi-functional polymerizable compound B1 having an SI value of 3 or less in a skin sensitivity test;
a polymerization initiator C1 having no maximum absorption peak in a wavelength range of from 365 to 405 nm; and
a hydrogen donor D,
CH 2 ═CH—CO—N(R 1 )—R 2 —CO—O—R 3   Chemical formula 1

where R 1 represents a hydrogen atom or an alkyl group comprising a linear or branched chain comprising one to four carbon atoms, R 2 and R 3 each independently represent an alkyl group comprising a linear or branched chain comprising one to four carbon atoms, and a total number of carbon atoms of R 1 , R 2 , and R 3 is from two to six,

where X represents a ring structure comprising a nitrogen atom and two to five carbon atoms, R 4 represents a single bond or an alkyl group comprising a linear or branched chain comprising one to three carbon atoms, R 5 represents a linear or branched chain comprising one to three carbon atoms, and a total number of carbon atoms of X, R 4 , and R 5 is from three to six.

2. The active energy ray curable composition of claim 1 , wherein the acrylamide compound A1 is represented by Chemical formula 1 and R 3 represents an alkyl group comprising one or two carbon atoms.

3. The active energy ray curable composition of claim 1 , wherein the multi-functional polymerizable compound B1 comprises at least one member selected from the group consisting of diethylene glycol dimethacrylate (2G), DCP, trimethylol propane trimethacrylate (TMPT), A-BPE-10, APG-700, 3-acetyl-1,2-dimethacryloyloxy propane, HX-620, DPEA-12, DPCA-60, and RP-1040.

4. The active energy ray curable composition of claim 1 , further comprising no organic solvent.

5. An active energy ray curable ink, comprising:
the active energy ray curable composition of claim 1 .

6. An inkjet method, comprising discharging the active energy ray curable ink of claim 5 .

7. A composition accommodating container, comprising:
the active energy ray curable ink of claim 5 ; and
a container comprising the active energy ray curable composition or an active energy ray curable ink comprising the active energy ray curable composition.

8. A two or three dimensional image forming apparatus, comprising:
the active energy ray curable ink of claim 5 ;
a container comprising the active energy ray curable composition or the active energy ray curable ink; and
an irradiator configured to emit active energy rays.

9. The two or three dimensional image forming apparatus of claim 8 , wherein the irradiator comprises an ultraviolet light emitting diode (UV-LED) that emits an ultraviolet ray having a peak in a wavelength range of from 365 to 405 nm.

10. A two or three dimensional image forming method, comprising:
applying the active energy ray curable ink of claim 5 ; and
irradiating the active energy ray curable ink with an active energy ray to form a two or three dimensional image.

11. The two or three dimensional image forming method of claim 10 , wherein the active energy ray is an ultraviolet ray having a peak in a wavelength range of from 365 to 405 nm emitted by an ultraviolet light emitting diode (UV-LED).

12. Cured matter, comprising:
the active energy ray curable composition of claim 1 or an active energy ray curable ink comprising the active energy ray curable composition.

13. Decorative matter, comprising:
a substrate: and
a surface decoration formed of the cured matter of claim 12 on the substrate.

14. An artificial nail composition, comprising:
the active energy ray curable composition of claim 1 .

15. A nail decorative material, comprising:
the artificial nail composition of claim 14 .

16. An artificial nail, comprising:
cured matter of the artificial nail composition of claim 14 .
