The polymerization stability and the chemical stability and the water resistance of resin films are improved. A surfactant composition according to an embodiment contains a surfactant (A) represented by general formula (1) and an anionic surfactant (B) having a hydrophobic group different from that of the surfactant (A). In the formula, Rrepresents one or two groups selected from groups below, Drepresents a polymerizable unsaturated group represented by chemical formula D-1 or D-2 below, Rrepresents a hydrogen atom or a methyl group, m1 and m2 represent 1 to 2, Arepresents an alkylene group with 2 to 4 carbon atoms, and m3 represents 1 to 100. 

Surfactant composition

The polymerization stability and the chemical stability and the water resistance of resin films are improved. A surfactant composition according to an embodiment contains a surfactant (A) represented by general formula (1) and an anionic surfactant (B) having a hydrophobic group different from that of the surfactant (A). Rrepresents an alkyl group with 8 to 14 carbon atoms, A represents an alkylene group with 2 to 4 carbon atoms, and n representing an average number of moles of an oxyalkylene group added represents 1 to 100. 

The present invention relates to an aqueous resin dispersion, obtained by subjecting a polymerizable compound (C) containing a compound (C1) having a carbon-carbon unsaturated bond to an emulsion polymerization in the presence of a surfactant (A) and a surfactant (B) free from a radical-polymerizable substituent.

Water-based resin dispersion and coating material

A gel composition having high adhesion, high whitening resistance, and high high-temperature stability is provided. The gel composition includes a polyoxyalkylene alkyl ether (A) represented by general formula (1) and water (B).R&#x2014;O&#x2014;(PO)-(EO)&#x2014;H&#x2003;&#x2003;(1) In the formula (1), R is a linear alkyl group having 12 to 22 carbon atoms, PO represents an oxypropylene group, EO represents an oxyethylene group, m and n each represent an average number of moles added, m is a number of 1 to 20, and n is a number of 1 to 80. PO and EO are added in a configuration of block addition.
