PCT No. PCT/JP96/02181 Sec. 371 Date Feb. 25, 1998 Sec. 102(e) Date Feb. 25, 1998 PCT Filed Aug. 2, 1996 PCT Pub. No. WO97/06193 PCT Pub. Date Feb. 20, 1997A room temperature curing composition of this invention comprises an emulsion obtained by multi-stage emulsion polymerization of monomers, the emulsion comprising emulsion particles, a core of which comprises (A) 1 to 30% by weight of silyl group-containing vinyl monomer, (B) 70 to 99% by weight of vinyl monomer copolymerizable with component (A), the outermost shell of which comprises (A) 0.1 to 30% by weight of silyl group-containing vinyl monomer and (B) 40 to 99.4% by weight of vinyl monomer copolymerizable with component (A), and (D) 0.5 to 30% by weight of hydrophilic vinyl monomer. The room temperature curing composition of this invention has a stable silyl group, and a much improved film-forming ability after long-term storage and it also shows excellent mechanical stability, water-resistance, durability and white enamel gloss.
