Emulsion composition and production method thereof, and laminate and production method thereof

A production method of an emulsion composition comprising:

• mixing a dispersion medium comprising water as a principal component, a polymerizable compound comprising two or more (meth)acryloyl groups, and a reactive surfactant;
• and
• applying a stress to a mixture obtained by the mixing,
• wherein an oil droplet diameter D90 corresponding to a diameter at cumulative 90% by volume in oil droplet size distribution of oil droplets obtained by the applying, measured according to a laser diffraction and scattering measurement process is less than 1.8 μm, and
• wherein the oil droplets comprise, as the reactive surfactant, a compound represented by formula (1):
• wherein, in the formula (1), X represents a monovalent group that comprises an aromatic ring, an ethylenic double bond or a combination thereof;
• le represents an alkylene group having 2 to 4 carbon atoms;
• n is an integer of 5 to 150, wherein a plurality of R1s are identical or different;
• R2 represents a hydrogen atom, —PO(OM)2-SO3M or a monovalent ethylenic double bond-containing group, wherein each M independently represents a hydrogen atom, an ammonium group or a metal atom, and at least one of X and R2 represents a group comprising a monovalent ethylenic double bond.
