A surface active agent composition is prepared including: a polymerizable monomer surface active agent and a polymerizable dimer surface active agent represented by the following chemical formula. In the following chemical formula, R
1
s each are independently an alkyl group having 8 to 30 carbon atoms, R
2
s each are independently hydrogen or a methyl group, As each are independently an alkylene group having 2 to 4 carbon atoms or a substituted alkylene group, and ns each are independently an integer from 0 to 200. The surface active agent composition is capable of providing for an emulsion exhibiting excellent mechanical stability and polymerization stability, which in turn is capable of forming a film having sufficiently high adhesion and water resistance.

Conjugation agents of the formula:
are described, wherein S
x
is —S—, —SO— or —SO
2
—; R
s
is a carbon-containing substituent that does not include a cyano group; each R is a substituent, with at least one R having a reaction site that is not a carboxylic acid; n is 0-5; each A is carbon or nitrogen, with the proviso that no more than three A can be nitrogen; and S
x
—R
s
is a leaving group. The conjugation agents have good thiol reactivity and selectivity, and good stability with regard to hydrolysis.
